Everest Three High Passes Trek Overview
The Everest Three High Passes Trek is the most complete and adventurous journey in the Everest (Khumbu) region. Instead of following a single valley in and out, the route loops across the region, linking three high Himalayan passes, Kongma La (5,535 m), Cho La (5,420 m) and Renjo La (5,360 m), with the iconic highlights of Everest Base Camp, Kala Patthar and the Gokyo Lakes. Over about three weeks, you'll cross glaciers, climb rocky passes, stay in remote Sherpa settlements and enjoy close-up views of Everest, Lhotse, Makalu, Cho Oyu, Ama Dablam and dozens of other peaks. It's a demanding trek for fit, experienced trekkers, and one of the most rewarding adventures in the Himalayas. With Nepal Trip Services, you'll have expert guidance, well-planned acclimatization and full support from start to finish.

The Three High Passes
Kongma La (5,535 m): The highest and toughest of the three passes connects Chhukung with Lobuche. A long, rocky climb leads to a remote summit marked with prayer flags, with views of Makalu, Lhotse and the Khumbu Glacier.
Cho La (5,420 m): This dramatic pass links the Everest Base Camp valley with the Gokyo valley. The crossing includes a short glacier walk on the far side and gives striking views of Cholatse and Ama Dablam.
Renjo La (5,360 m): Known for one of the finest Everest panoramas in the Khumbu, Renjo La looks back over the Gokyo Lakes and the Ngozumpa Glacier to Everest, Lhotse and Makalu. It's the last and most scenic of the three.
The Classic Route
The trek starts with a scenic flight to Lukla, followed by the trail through pine forests and suspension bridges to Namche Bazaar (3,440 m), where you'll spend an acclimatization day. From there, the route passes Tengboche Monastery and Dingboche to the quiet valley of Chhukung, then crosses Kongma La to Lobuche. Next comes the highlight many trekkers dream of: Everest Base Camp (5,364 m) and the sunrise from Kala Patthar. You'll then cross Cho La into the Gokyo valley, explore the turquoise Gokyo Lakes, climb Gokyo Ri (5,357 m), and finish with Renjo La before descending through the peaceful Bhote Koshi Valley and historic Thame back to Namche and Lukla.
Sherpa Culture & Natural Beauty
Beyond the passes, this trek offers a deep cultural experience. Visit Tengboche, the largest monastery in the Khumbu, along with the ancient Thame Monastery and the villages of Khumjung and Pangboche, where Sherpa traditions and Buddhist faith shape everyday life. The entire route lies within Sagarmatha National Park, a UNESCO World Heritage Site that's home to the Himalayan tahr, musk deer, Danphe pheasant and the elusive snow leopard.
Difficulty & Acclimatization
The Three Passes Trek is graded strenuous. It involves long walking days of 6–9 hours, several nights above 4,500 m and steep, rocky or icy sections on the passes. Previous high-altitude trekking experience and excellent fitness are strongly recommended. To reduce the risk of altitude sickness, the itinerary includes acclimatization days in Namche Bazaar and Dingboche, and the anticlockwise route builds altitude gradually before the highest pass.

Everest Three High Passes Trek Preparation & Training
Good preparation is the key to a safe and enjoyable Everest Three High Passes Trek. We recommend starting your training 8–12 weeks before departure. Build cardiovascular endurance with running, cycling, swimming or brisk uphill walking 4–5 times a week, and add strength training such as squats, lunges, step-ups and core exercises to prepare your legs and back for steep climbs and long descents over Kongma La, Cho La and Renjo La. The most effective training is hiking with a daypack of 6–8 kg on hilly terrain or stairs, gradually building up to back-to-back long hikes of 6–8 hours, much like real trekking days in the Khumbu. If you can, gain some experience at altitude beforehand, and get a medical check-up, especially if you have heart, lung or blood pressure conditions. Practical preparation matters too: break in your trekking boots, get used to using trekking poles, and pack the right gear, including warm layers and microspikes for icy pass crossings. Mental preparation is just as important, as the trek takes patience, a steady pace and a positive attitude on cold mornings and long days. For a complete week-by-week plan, fitness tests and expert tips, read our Everest Three High Passes Trek Training & Fitness Guide. Before your trip, Nepal Trip Services will share a detailed packing list and training guidance, so you arrive in Kathmandu confident and ready.
Is the Everest Three High Passes Trek Suitable for Beginners?
In most cases, the Everest Three High Passes Trek is not recommended for complete beginners. It's one of the toughest teahouse treks in Nepal, with long days of 6–9 hours, three passes above 5,300 m, several nights above 4,500 m and rough, rocky or icy trail sections. These demand excellent fitness, mental stamina and ideally previous high-altitude trekking experience. That said, a very fit and determined beginner who has done regular hiking or endurance training can complete it with 2–3 months of focused preparation, a well-paced itinerary with extra acclimatization days and the support of an experienced guide. Many first-time Himalayan trekkers find it more rewarding, and safer, to start with the Classic Everest Base Camp Trek or the Gokyo Lakes Trek to build altitude experience, or to try a gentler route like the Poon Hill Trek or the Everest View Trek. Not sure if you're ready? Read our complete guide, Can Beginners Do the Everest Three High Passes Trek?, or let Nepal Trip Services look at your fitness and trekking background and help you choose the right Himalayan adventure, or customize the Three Passes route with extra rest days to suit you.

Everest Three High Passes Trek: Additional Information
Best Time for the Everest Three High Passes Trek
The best time for the Everest Three High Passes Trek is mid-October to November and April to May. During these months, the weather is stable, the skies are clear and the three passes, Kongma La, Cho La and Renjo La, are usually free of heavy snow. Choosing the right season matters more on this route than on almost any other Everest trek, because conditions on the passes can make the difference between a safe crossing and a turned-back day.

How Difficult Is the Everest Three High Passes Trek?
The Everest Three High Passes Trek is graded strenuous, and it's one of the most demanding teahouse treks in Nepal. You don't need any technical climbing skills, but you do need excellent fitness, stamina and ideally previous high-altitude trekking experience. The challenge comes from the combination of long days, high altitude and three tough pass crossings above 5,300 m.

- EBC or Gokyo trekkers looking for a bigger challenge
- Determined, well-trained hikers willing to prepare for 2–3 months
- Not ideal for complete beginners or anyone with heart or lung conditions
How to Make It Easier
- Train for 8–12 weeks with cardio, strength work and long hikes carrying a pack.
- Follow the anticlockwise route for better acclimatization.
- Walk slowly and drink 3–4 litres of water a day.
- Use microspikes and trekking poles on icy, steep sections.
- Start pass days early (around 4–5 AM) to avoid afternoon wind and cloud.
- Hire a porter, so you only carry a light daypack.
With Nepal Trip Services' experienced guides, gradual acclimatization and daily health checks, the Everest Three High Passes Trek is a demanding but achievable Himalayan adventure.
Altitude Sickness & Acclimatization
On the Everest Three High Passes Trek, you'll spend 8–10 nights above 4,500 m and cross three passes above 5,300 m, so altitude sickness (AMS) is the biggest health risk. It can affect anyone, whatever their age or fitness. The good news is that it's preventable and manageable with a gradual ascent, proper acclimatization days and close monitoring by an experienced guide.

How We Prevent Altitude Sickness
- Gradual ascent: No big jumps in sleeping altitude above 3,000 m
- Acclimatization days in Namche Bazaar and Dingboche/Chhukung
- "Climb high, sleep low" after each pass and viewpoint
- Daily oxygen and pulse checks with a pulse oximeter
- Flexible itinerary with options to rest, skip Kongma La or descend if needed
Your Part
- Walk slowly, at a pace where you can still talk comfortably.
- Drink 3–4 litres of water a day, and avoid alcohol and smoking.
- Eat well, especially carbohydrates such as dal bhat.
- Speak up early and tell your guide about any symptoms.
- Ask your doctor before the trip about altitude medication such as Diamox.
If Symptoms Get Worse
Descending is the most effective treatment. In serious cases, Nepal Trip Services coordinates helicopter evacuation with your insurer. This is why insurance covering trekking up to 6,000 m and helicopter rescue is mandatory for this trek.
Go slow, listen to your body and trust your guide. With Nepal Trip Services, every stage of your Everest Three High Passes Trek is planned with your safety in mind.
Kongma La, Cho La & Renjo La Crossing Guide
The three high passes are the heart of the Everest Three High Passes Trek. Each one has its own character: Kongma La is the highest and most remote, Cho La is the most technical with its glacier crossing, and Renjo La has the finest Everest views. Here's what to expect on each crossing (anticlockwise route).

Kongma La (5,535 m): The Highest Pass
- Route: A long, steady climb from Chhukung past small frozen lakes to the prayer-flag-covered summit.
- Views: Makalu, Lhotse, Ama Dablam and the Imja Valley.
- Descent: A steep, rocky drop, then a 1–1.5 hour crossing of the Khumbu Glacier to Lobuche.
- Tip: It's the most remote pass, with no teahouses between Chhukung and Lobuche, so carry enough water and snacks.
Cho La (5,420 m): The Glacier Pass
- Route: A climb from Dzongla across boulders, steep scree and a short glacier section near the top.
- Views: Cholatse, Ama Dablam and the dramatic glacier landscape.
- Descent: A steep, rocky path down to Thagnak, at the edge of the Ngozumpa Glacier.
- Tip: Microspikes are essential. The glacier can be icy, especially early in the morning or after snowfall.
Renjo La (5,360 m): The Best Views
- Route: A climb on stone steps from Gokyo, past the shore of Gokyo Lake.
- Views: One of the finest panoramas in the Khumbu: Everest, Lhotse, Makalu, Cho Oyu and the turquoise lake below.
- Descent: Long and steep on loose rock to the quiet Bhote Koshi Valley and Lungden.
- Tip: Take your time at the top. It's the last pass, and the view is unforgettable.
Pass-Day Essentials
- Microspikes and trekking poles
- Down jacket, windproof shell, warm gloves and a hat
- 2–3 litres of water (in an insulated bottle), plus energy snacks and a packed lunch
- Headlamp for the pre-dawn start
- Sunglasses (Category 3–4) and SPF 50+ sunscreen for snow glare
Crossing Tips
- Start early. Weather is clearest in the morning, and wind picks up in the afternoon.
- Walk slowly and steadily, taking short, regular breaks.
- Follow your guide closely on glacier and scree sections.
- Be ready to turn back. If weather or health conditions are poor, safety comes first.
- Use the alternative route: Kongma La can be skipped via Dingboche and Lobuche if needed.
With Nepal Trip Services' experienced guides leading every crossing, you can take on Kongma La, Cho La and Renjo La safely and confidently on your Everest Three High Passes Trek.
Clockwise vs Anticlockwise Route
The Everest Three High Passes Trek is a loop, so you can do it in either direction. Most trekkers, and Nepal Trip Services, choose the anticlockwise route (Kongma La → Cho La → Renjo La) because it builds altitude more gradually and reaches Everest Base Camp mid-trek. The clockwise route (Renjo La → Cho La → Kongma La) is quieter and saves Everest Base Camp for the end, but it needs extra acclimatization at the start.

Why We Recommend Anticlockwise
- Safer acclimatization, with rest days before going above 5,000 m
- The gentler side of each pass is climbed, through Chhukung, Dzongla and Gokyo
- Easy backup plan: If Kongma La isn't possible, the route continues via Dingboche to Lobuche
- Everest Base Camp in the middle of the trek, with time left to explore Gokyo afterwards
Choosing Your Direction
- First time crossing high passes? Go anticlockwise.
- Want quieter trails and Everest as the grand finale? Go clockwise, with an extra acclimatization day.
- Short on time? Anticlockwise is easier to adjust if the weather or your health changes.

Lukla Flights & Ramechhap Airport Guide
Every Everest Three High Passes Trek begins and ends with a flight to Tenzing–Hillary Airport in Lukla (2,860 m), one of the world's most famous mountain airstrips. Its short, sloping runway sits on the edge of a mountainside, and the flight in gives you your first views of the high Himalayas. In the busy spring and autumn seasons, most Lukla flights depart from Manthali Airport in Ramechhap instead of Kathmandu, so it helps to know what to expect.

Teahouse Accommodation & Facilities
On the Everest Three High Passes Trek, you'll stay in teahouses: family-run mountain lodges run by Sherpa families who offer warm hospitality, hearty meals and a cozy place to rest. Standards vary a lot along the circuit. Namche Bazaar and Lukla have comfortable lodges with modern facilities, while remote stops such as Dzongla, Thagnak and Lungden are simple and basic. Every night, though, ends in a warm dining hall with mountain views.

Food, Drinking Water & Hygiene
Eating well, staying hydrated and keeping clean are some of the most important ways to stay healthy and strong on the Everest Three High Passes Trek. The teahouses along the route serve fresh, hearty meals made for trekkers, and safe drinking water is easy to get with a little planning. Basic hygiene habits go a long way toward avoiding stomach upsets at high altitude.

Smart Eating Tips
- Eat plenty of carbohydrates. They help your body work better at altitude.
- Choose vegetarian meals above Namche. Meat is carried up by porters and may not be fresh.
- Eat even when you're not hungry. Appetite loss is common at altitude.
- Expect food prices to rise the higher you go, as all supplies are carried in.

Hygiene on the Trek
- Wash or sanitize your hands before every meal and after using the toilet.
- Carry toilet paper, wet wipes and biodegradable soap.
- Expect limited showers above 4,500 m; wet wipes are a trekker's best friend.
- Use toilets at teahouses whenever you can, and pack out all your waste.
- Avoid sharing water bottles to prevent illness spreading in the group.
If Your Stomach Gets Upset
- Drink oral rehydration salts (ORS) and rest.
- Stick to plain foods such as rice, toast, soup or boiled potatoes.
- Tell your guide if symptoms last more than a day.
Our Nepal Trip Services guides choose clean, trusted teahouses and help you eat and drink well, so you have the energy you need for every pass on the Everest Three High Passes Trek.
Wi-Fi, Mobile Network & Charging
Staying connected on the Everest Three High Passes Trek is possible in most villages, thanks to Everest Link Wi-Fi, mobile networks and teahouse charging points. Connectivity becomes limited or unavailable on the passes and at remote stops such as Dzongla, Thagnak and Lungden, so plan to be offline for a day or two at a time.

Everest Link Wi-Fi
- The most reliable internet in the Khumbu, available in most villages
- Prepaid cards are sold at teahouses, with packages by data amount or number of days
- Speeds are slow and shared: fine for messages and photos, but not for video calls
Mobile SIM Cards
- Buy a local SIM in Kathmandu (NTC or Ncell) with your passport and a photo.
- NTC usually has better coverage at higher altitudes than Ncell.
- Check that your phone is unlocked before you travel.
Charging Your Devices
- Teahouses charge per device or per hour, and the price rises with altitude.
- Power comes from solar or micro-hydro at high stops and may be limited on cloudy days.
- Charging is usually in the dining hall, not your room, above Namche.
- Nepal uses Type C, D and M sockets (230V), so bring a universal adapter.
Connectivity Tips
- Carry a 20,000 mAh power bank to keep your phone and camera going.
- Keep batteries warm inside your sleeping bag at night, as cold drains them quickly.
- Download offline maps and entertainment before leaving Kathmandu.
- Use airplane mode when there's no signal to save battery.
- Let family know you'll be offline on pass days.
- Your guide carries a phone for safety updates and emergencies.
Enjoy the chance to unplug and take in the Himalayas. When you need to stay in touch, Nepal Trip Services keeps you connected and supported throughout your Everest Three High Passes Trek.

Money-Saving Tips
- Carry enough NPR cash from Kathmandu. ATMs are only in Lukla and Namche and don't always work.
- Use refill stations and purification tablets instead of buying bottled water.
- Bring snacks from Kathmandu, where they're much cheaper.
- Use a power bank to cut down on charging costs.
- Rent bulky gear (down jacket, sleeping bag) in Thamel rather than buying it.
- Join a small group to lower the per-person package cost.
With clear, honest pricing and no hidden fees, Nepal Trip Services makes it easy to budget for your Everest Three High Passes Trek.
Packing List & Microspikes Guide
Packing the right gear is essential for the Everest Three High Passes Trek, where temperatures can drop below -20°C and the pass crossings can be icy. Keep your load light, layer your clothing well, and don't forget the most important piece of pass-day kit: microspikes.
Essential Packing Checklist
| Category |
Must-Have Items |
| Clothing |
Thermal base layers, fleece, down jacket (-20°C), waterproof shell jacket & trousers, trekking trousers |

Weight limit: Porters carry up to 12–15 kg per trekker. Leave extra luggage at your Kathmandu hotel.
Microspikes Guide
What are microspikes?
Microspikes are lightweight traction devices with small steel spikes and chains that stretch over your trekking boots. They give you a firm grip on ice, hard snow and frozen trails, and unlike crampons, you don't need any technical skills to use them.
| Detail |
Information |
| Why You Need Them |
Icy sections on Cho La glacier, frozen trails on Kongma La, and snow on Renjo La early or late in the season |
| Microspikes vs Crampons |
Microspikes are enough for the Three Passes; crampons aren't usually needed unless there's heavy snow |
| Where to Get Them |
Buy or rent in Thamel (Kathmandu), or rent in Namche Bazaar |
| Fit |
Choose the right size for your boots and test them before the trek |
| Weight |
About 300–400 g per pair, easy to carry in your daypack |
How to Use Microspikes
- Put them on before you reach icy sections, not halfway across them.
- Walk with flat feet and short steps to keep all the spikes in contact with the ice.
- Use your trekking poles for extra balance.
- Take them off on rocky ground to avoid wear and slipping on bare rock.
- Dry them after use and check the chains and rubber for damage.
Smart Packing Tips
- Layer, don't bulk up. Several thin layers are warmer and more flexible than one thick jacket.
- Keep pass-day essentials in your daypack: microspikes, a down jacket, gloves, water and snacks.
- Rent bulky items such as down jackets and sleeping bags in Thamel to save luggage space.
- Pack electronics and documents in dry bags.
- Do a full gear check in Kathmandu with your guide before flying to Lukla.
Before you fly to Lukla, Nepal Trip Services checks your gear and helps you rent or buy anything missing, including microspikes, so you're fully prepared for every pass on the Everest Three High Passes Trek.
Travel Insurance & Helicopter Rescue
Travel insurance is mandatory for the Everest Three High Passes Trek with Nepal Trip Services. The route crosses three passes above 5,300 m and reaches 5,644 m at Kala Patthar, in remote areas several days' walk from the nearest road or hospital. In a serious emergency, a helicopter evacuation is often the only fast way out, and it's very expensive without proper insurance.
What Your Policy Must Cover
| Coverage |
Requirement |
| High-Altitude Trekking |
Up to 6,000 m (the passes and Kala Patthar are above 5,300 m) |
| Helicopter Rescue & Evacuation |

Before You Travel
- Send us a copy of your policy and the insurer's 24-hour emergency number.
- Make sure the name on your policy matches your passport.

- Tell your guide about symptoms early. Quick action can prevent the need for a rescue.
Your safety comes first. With the right insurance and Nepal Trip Services' 24/7 emergency support, you can take on the Everest Three High Passes Trek with complete peace of mind.

Frequently Asked Questions (FAQs)
1. What is the Everest Three High Passes Trek?
The Everest Three High Passes Trek is a full circuit of the Khumbu region that crosses three high Himalayan passes: Kongma La (5,535 m), Cho La (5,420 m) and Renjo La (5,360 m). It combines Everest Base Camp, Kala Patthar, the Gokyo Lakes and Gokyo Ri in one journey, which makes it the most complete trek in the Everest region.
2. How long is the Everest Three High Passes Trek?
The standard itinerary is 19 days, including arrival and departure in Kathmandu, with about 16–17 days of trekking. Fit trekkers can do it in 18 days, but we recommend 20–21 days for safer acclimatization and buffer time for Lukla flight delays.
3. What is the maximum altitude of the trek?
The highest point is Kala Patthar (5,644 m / 18,519 ft), the famous Everest viewpoint above Gorak Shep. The highest of the three passes is Kongma La (5,535 m).
4. How many kilometres is the Three Passes Trek?
The total trekking distance is about 160–170 km, starting and ending in Lukla. Daily distances range from 8 to 15 km, depending on terrain and altitude.
5. Which direction is best: clockwise or anticlockwise?
Most trekkers go anticlockwise (Kongma La → Cho La → Renjo La). This direction lets you acclimatize gradually through Namche, Dingboche and Chhukung, and the steeper sides of the passes become climbs rather than descents, which is generally safer. Clockwise is possible but needs extra acclimatization at the start.
6. How difficult is the Everest Three High Passes Trek?
It's graded strenuous. You'll walk 6–9 hours a day, spend many nights above 4,500 m, and cross steep, rocky and sometimes icy passes. No technical climbing is needed, but excellent fitness and stamina are essential.
7. Can beginners do the Three Passes Trek?
It isn't ideal for complete beginners. Previous high-altitude trekking experience, such as the Classic Everest Base Camp Trek or the Gokyo Lakes Trek, is strongly recommended. Very fit beginners may manage it with thorough training and extra rest days.
8. Which is the hardest pass?
Kongma La (5,535 m) is usually considered the hardest, because it's the highest and involves a long, steep climb and a rocky descent onto the Khumbu Glacier. Cho La is technically the trickiest, with a short glacier crossing that can be icy.
9. How should I train for the trek?
Start training 8–12 weeks before departure, with cardio (running, cycling, swimming), strength training for your legs and core, and long hikes carrying a 6–8 kg daypack on hills or stairs. Back-to-back training hikes of 6–8 hours are the best preparation.
10. Is altitude sickness a risk on this trek?
Yes. With several nights above 4,500 m, Acute Mountain Sickness (AMS) is the biggest risk. Our itinerary includes acclimatization days in Namche Bazaar and Dingboche, a gradual ascent, and daily oxygen checks with a pulse oximeter to keep you safe.
11. What are the symptoms of altitude sickness?
Common symptoms include headache, nausea, dizziness, fatigue, loss of appetite and trouble sleeping. Serious signs, such as breathlessness at rest, confusion or loss of coordination, need immediate descent and medical attention.
12. What happens if I can't cross a pass?
Your guide will always put safety first. If weather, fitness or altitude make a pass unsafe, there are alternative routes: Kongma La can be skipped by going via Dingboche and Lobuche, for example. Your guide may also adjust the itinerary or add rest days.
13. Is the Three Passes Trek safe?
Yes, with the right preparation and support. Trekking with an experienced licensed guide, following a well-paced itinerary, carrying proper gear such as microspikes, and having insurance with helicopter rescue make the trek safe and manageable.
14. When is the best time for the Everest Three High Passes Trek?
The best seasons are autumn (late September–November) and spring (March–May), when the weather is stable, the skies are clear and the passes are usually free of heavy snow.
15. Can I do the trek in winter or the monsoon?
Winter (December–February) brings heavy snow and extreme cold on the passes, and some high teahouses close. Monsoon (June–August) means rain, clouds, slippery trails and frequent Lukla flight delays. Neither season is recommended for the full Three Passes route.
16. How cold does it get on the passes?
In peak season, daytime temperatures at high altitude are around 0°C to 10°C, while nights can drop to -10°C to -20°C. Strong winds on the passes make it feel even colder, so good layers and a warm sleeping bag are essential.
17. Which permits do I need for the Three Passes Trek?
You need two permits: the Sagarmatha National Park entry permit (about NPR 3,000) and the Khumbu Pasang Lhamu Rural Municipality permit (about NPR 3,000). Nepal Trip Services arranges both for you.
18. How do I get to Lukla?
You'll take a short domestic flight to Lukla (2,860 m). It's about 35–40 minutes from Kathmandu, or 20 minutes from Ramechhap (Manthali) Airport during peak seasons, when many flights are moved there. We handle all your flight bookings and transfers.
19. What if my Lukla flight is delayed or cancelled?
Lukla flights depend on the weather and can be delayed. We recommend adding 1–2 buffer days to your schedule. If you're short on time, an optional helicopter flight can be arranged at extra cost.
20. What kind of accommodation is available?
You'll stay in 3★ hotels in Kathmandu and teahouses on the trek. Lower villages offer comfortable rooms, some with attached bathrooms. Remote stops such as Dzongla, Thagnak and Lungden have basic twin rooms with shared toilets.
21. What food is available on the trail?
Teahouses serve dal bhat, noodles, soups, pasta, potatoes, momos, eggs, porridge and Tibetan bread. Dal bhat is the best energy meal, with free refills. Vegetarian meals are easy to find, and we recommend avoiding meat at higher altitudes.
22. Is drinking water safe on the trek?
Don't drink untreated tap or stream water. Use water purification tablets, a filter, or buy boiled water from teahouses. Many villages have safe drinking-water refill stations, a cheaper and greener choice than bottled water.
23. Is there Wi-Fi and phone signal on the trek?
Yes, in most villages. Everest Link Wi-Fi cards work across much of the region, and NTC and Ncell have coverage in places. Signal is limited or unavailable on the passes and in remote spots like Dzongla and Lungden.
24. Can I charge my devices on the trail?
Yes. Most teahouses offer charging for a small fee, and the cost rises with altitude. Carry a power bank and keep batteries warm, as the cold drains them quickly.
25. Do I need special equipment for the passes?
You don't need technical climbing gear, but microspikes or crampons are highly recommended for the icy sections, especially on Cho La. You'll also need trekking poles, a down jacket, a sleeping bag rated to -15°C to -20°C and good waterproof boots.
26. Do I need a guide for the Three Passes Trek?
A licensed guide is strongly recommended, and trekking rules in Nepal increasingly require one. The passes involve route-finding, changing weather and glacier sections, so an experienced guide greatly improves both your safety and your chances of success.
27. How much weight can a porter carry?
Our porters carry up to 25 kg in total, shared between two trekkers (about 12–15 kg each). Carry only a light daypack with water, snacks, warm layers and essentials.
28. Is travel insurance required?
Yes. Travel insurance is mandatory and must cover high-altitude trekking up to 6,000 m, emergency helicopter evacuation and medical treatment. Please send us a copy of your policy before the trek.
29. How much money should I carry on the trek?
Budget about US$20–30 per day for extras such as Wi-Fi, charging, hot showers, snacks, drinks and tips. Carry Nepali Rupees in cash, as ATMs are only available in Lukla and Namche Bazaar and may not always work.
30. How do I book the Everest Three High Passes Trek?
You can book online or contact Nepal Trip Services by email or WhatsApp. A deposit confirms your trek, and you pay the balance on arrival in Kathmandu. For spring and autumn, we recommend booking 2–3 months in advance to secure flights and teahouses.
