Everest Three Passes Trek - 21 Days

The Everest Three Passes Trek takes you through the spectacular scenery of the Khumbu region and gives you the opportunity to experience the history, traditions and culture of the Sherpa people. The Sherpa community have been living in the Khumbu region for generations. They originally came from eastern Tibet and settled into the high Himalayan valleys with their Tibetan Buddhist traditions, language, customs and mountain way of life. They have grown up in the region and over the years have developed a very strong relationship with the mountains, learning to live in the high altitude environment whilst maintaining their cultural identity.

Tibetan Buddhism is the bedrock of Sherpa culture and is very much a part of everyday life. As you make your way along the Everest Three Passes route you'll come across monasteries, traditional villages, prayer walls, mani stones and of course the ubiquitous prayer flags. Tengboche and Thame are two of the most significant places in terms of both their religious and cultural importance. Tengboche Monastery is one of the most important Buddhist monasteries in the Khumbu and it has a very peaceful, meditative atmosphere with absolutely stunning views across the Himalayas. Mani Rimdu is the major festival in the region and it's a time when the whole community comes together with masked dances, Buddhist rituals, prayers and all the other associated festivities.

The history of the Everest region is also inextricably linked to the rise of Himalayan mountaineering. It was when Hillary and Tenzing Norgay reached the summit of Everest in 1953 that the Khumbu region became world famous as a premier mountaineering destination. The Sherpas have always been at the heart of Himalayan exploration, providing the expeditions with support in all forms (expeditions, trekking, mountain rescue etc). Their intimate knowledge of the mountains, their high altitude skills and their very welcoming nature have made them an absolutely integral part of the story of trekking and mountaineering in Nepal.

On the Everest Three Passes Trek you experience the rich heritage as you cross Kongma La, Cho La and Renjo La and visit the Sherpa villages of Namche Bazaar, Thame and Gokyo. You'll see the traditional stone houses, the local farming, the yak herding, the Buddhist buildings and of course the very warm welcome from the local families. It's more than just a trek in the Himalayas really, it's a real cultural experience and you get a real insight into Sherpa life and the heritage of the Everest region.

The Everest Three Passes Trek is a very tough and very rewarding trek and is one of the top treks in the Khumbu region of Nepal. You do the Kongma La (5,535m), the Cho La (5,420m) and the Renjo La (5,360m). Each of the passes gives you a very different flavour of the Himalayas with the dramatic mountain scenery, the glacial valleys, the remote trails and the views of some of the highest peaks in the world (Everest, Lhotse, Makalu and Cho Oyu to name but a few).

Kongma La Pass (5,535m) is the highest of the three and one of the most difficult sections of the trek. It's situated between Chhukung and Lobuche and provides superb views of the surrounding Himalayan peaks (Lhotse, Nuptse and the Khumbu Glacier in particular). The route is very steep, very rocky and at high altitude so you do need to be well acclimatized and in good physical condition.

Cho La Pass (5,420m) takes you from the Gokyo Valley to the Everest Base Camp area. It's a very rugged pass with a lot of rock and a number of glacier crossings. There will be snow and ice in places at various times of the year. From the top you get one of the most spectacular views of the Himalayas. Cho La is a tough pass but it's one of the most rewarding sections of the trek.

Renjo La Pass (5,360m) is frequently touted as one of the very best viewpoints in the Everest region. It links the Gokyo and Thame valleys and provides absolutely spectacular views of Everest, Lhotse, Makalu and the strikingly blue Gokyo Lakes. As you descend into the Gokyo Valley the scenery is simply stunning. Doing all three passes is a major achievement and allows you to explore some of the most remote valleys, Sherpa villages, Buddhist monasteries and the sheer beauty of the Everest region.

The Everest Three Passes Trek – 21 Days is an extraordinary Himalayan adventure that combines challenging high-altitude trekking with the rich Buddhist culture and spiritual heritage of the Khumbu region. Along the way, trekkers can explore traditional Sherpa villages, visit ancient Buddhist monasteries, and experience the peaceful atmosphere of the Himalayan mountains. Monasteries such as Tengboche, Pangboche, and Thame offer a fascinating insight into Tibetan Buddhism, local traditions, prayer rituals, and the spiritual lifestyle of the Sherpa people.

A cultural highlight of this journey is visiting Tengboche Monastery, one of the most important Buddhist monasteries in the Everest region. Surrounded by spectacular Himalayan scenery, it provides a peaceful setting for meditation, prayer, and cultural exploration. Trekkers can also discover traditional monasteries, mani walls, prayer wheels, chortens, and colorful prayer flags along the trails. These sacred places reflect the deep connection between Buddhism, nature, and everyday life in the Khumbu region.

Beyond its cultural attractions, the trek offers an unforgettable adventure across three spectacular high mountain passes: Kongma La (5,535m), Cho La (5,420m), and Renjo La (5,360m). The 21-day itinerary allows time for proper acclimatization, exploration of traditional Sherpa settlements, and visits to iconic destinations such as Everest Base Camp, Kala Patthar, Gokyo Lakes, and the beautiful Gokyo Valley. With breathtaking mountain panoramas, ancient monasteries, and authentic Himalayan hospitality, this trek is ideal for adventurous travelers seeking both physical challenge and meaningful cultural experiences in the heart of the Everest region.

Sagarmatha National Park is one of Nepal's most spectacular natural sites and a UNESCO World Heritage Site in the NE Himalayas. Established in 1976 it has an area of some 1,148 sq km and includes Mount Everest (8,848.86m), the world's highest mountain, as well as a number of other Himalayan peaks. The park is a classic Himalayan landscape of deep valleys, alpine forests, rugged mountains, glaciers and high altitude ecosystems and is a premier destination for trekking, mountaineering and the general exploration of the natural world.

The park is renowned for its biological diversity and its very particular Himalayan setting. It's home to a number of rare and endangered species including the snow leopard, Himalayan tahr, musk deer, red panda and a variety of Himalayan birds. The lower areas are forested with pine, fir, birch and rhododendron, the upper areas being alpine plants, rock and permanent snow and ice. The Sherpa are resident here too and their way of life, with the monasteries, prayer flags and the mountain villages, give the park a very strong cultural and spiritual dimension.

The glacial lakes in the Himalayas are one of the most spectacular features of Sagarmatha National Park. The Gokyo Lakes (at approx 4,700- 5,000 m) are a group of very beautiful turquoise and emerald coloured freshwater lakes, set in a stunning valley flanked by the towering Himalayan peaks and glaciers. They are fed by glacial meltwater and are very sacred to both the Hindu and Buddhist communities. The Gokyo Valley also provides some of the most spectacular views of the Ngozumpa Glacier, one of the largest glaciers in the Himalayas, and the sheer scale of the glacial landscape is truly impressive.

Beyond their aesthetic value the glaciers and glacial lakes in Sagarmatha National Park are a key component of the Himalayan freshwater system, feeding the rivers that in turn support both people and the wider ecosystem downstream. Climate change, with its warmer temperatures and retreating glaciers, is creating problems in the form of larger glacial lakes and an increased risk of glacial lake outburst floods (GLOF). That's why conservation, responsible tourism and environmental awareness are so critical in order to protect these fragile mountain environments for the future. A visit to Sagarmatha National Park and its glacial lakes is a once in a lifetime opportunity to experience the natural beauty of Nepal, the mountain culture and the unique high altitude wilderness.

Everest Three Passes Trek Records and Highlights

The Everest Three Passes Trek takes you into the very heart of the world's highest mountain range, combining legendary viewpoints, high mountain passes, and rich Sherpa culture in one connected loop.

The Three High Passes

•       Kongma La – 5,535 m (18,159 ft), the highest pass of the circuit, with views over the Khumbu Glacier and Makalu.

•       Cho La – 5,420 m (17,782 ft), a glaciated pass connecting the Khumbu and Gokyo valleys.

Everest Base Camp and Kala Patthar

The circuit includes the classic visit to Everest Base Camp at approximately 5,364 meters, the starting point for Everest climbing expeditions, and a pre-dawn ascent of Kala Patthar (5,545 m), the highest point of the entire trek and the finest viewpoint for a close-up sunrise over Mount Everest, Lhotse, Nuptse, and Pumori.

A Once-in-a-Lifetime Himalayan Adventure

From ancient monasteries and traditional Sherpa villages to towering glaciers, turquoise lakes, and three demanding high passes, every step of the Three Passes Trek offers a unique adventure. Reaching all three passes, standing at Everest Base Camp, and watching sunrise from Kala Patthar are unforgettable moments that make this one of the most rewarding treks in the world.

To do the Everest Three Passes in the Khumbu area of Nepal you'll need a number of permits. For all the major trekking routes and high passes you'll need the Khumbu Pasang Lhamu Rural Municipality permit and the Sagarmatha National Park entry permit. This applies to all the passes including Kongma La (5,535m), Cho La (5,420m) and Renjo La (5,360m).

The Khumbu Pasang Lhamu Rural Municipality permit is a local entry permit which in effect funds the infrastructure, tourism, trail maintenance and community services in the Everest area. You can obtain this at the checkpoint in Lukla or Monjo (depending on your route and the current arrangements).

You need the Sagarmatha National Park Entry Permit to enter Sagarmatha National Park (a UNESCO World Heritage Site renowned for its Himalayan scenery, wildlife and Mount Everest). You can obtain this permit in Kathmandu or at the park entry point in Monjo. The fees are used to fund conservation, environmental protection and park management. You must have all your required permits and keep them safe as they may be checked at various checkpoints along the way. Fees and regulations are subject to change so it is essential to check the current requirements prior to departure. It is possible to book the permit via a registered trekking agency such as Nature Heaven Treks & Expedition which will take care of the permit process and ensure that all the correct documentation is in place prior to the trek.

Food & Beverages on the Everest Three Passes Trek

Nutritious and energy-rich meals are available throughout the trek, with teahouses offering a variety of local and international dishes to keep trekkers fueled for long days in the mountains. Menus are widest in Namche and Gokyo and become simpler at higher and more remote villages.

Popular Food Options

•       Dal Bhat (the most common and highly recommended trekking meal, often with free refills)

•       Fried rice and noodles (vegetable, chicken, or egg)

•       Soups (garlic soup is especially popular at high altitude)

•       Pasta and potatoes (boiled, fried, or mashed)

•       Momos, pancakes, oatmeal, and eggs

Popular Beverages

•       Tea (black, milk, and herbal varieties)

•       Coffee and hot chocolate

•       Hot lemon and ginger tea (great for altitude and digestion)

Drinking Water

Safe drinking water is available throughout the route. Trekkers are encouraged to use purified, boiled, or filtered water, supported by purification tablets, and to stay well-hydrated, which is essential for acclimatization at high altitude. A vegetarian diet is recommended at higher elevations.

Health & Risk Prevention on the Everest Three Passes Trek

Because the Three Passes Trek spends many days above 4,000 meters and crosses three passes over 5,300 meters, altitude-related illness — especially Acute Mountain Sickness (AMS) — is the main health challenge. AMS occurs when the body struggles to adapt to reduced oxygen levels at high elevation.

Common Symptoms of AMS

•       Headache

•       Nausea or vomiting

•       Dizziness

•       Fatigue or weakness

•       Loss of appetite

•       Difficulty sleeping

These symptoms should never be ignored, as they can worsen quickly at the altitudes reached on this trek.

Prevention and Safety Measures

•       Gradual Ascent – the anti-clockwise itinerary is designed for a steady, safe rise in altitude.

•       Proper Hydration – drink plenty of water throughout the day to support acclimatization.

•       Adequate Rest – avoid overexertion and maintain a steady pace, especially on the long pass days.

•       Acclimatization Days – scheduled rest days at Namche, Dingboche, and Gokyo help the body adapt.

With correct preparation, responsible trekking habits, and attention to early symptoms, most trekkers complete this demanding journey safely while fully enjoying the incredible Himalayan experience.

Guidelines for Safe Travel on the Everest Three Passes Trek

Safety is a top priority while crossing the high passes of the Khumbu, and following proper guidelines ensures a smoother and more enjoyable journey.

Essential Safety Guidelines

•       Trek with licensed guides – always travel with experienced, certified guides for safety, navigation, and pass-crossing support.

•       Stay hydrated – drink plenty of water to help your body adjust to high altitude.

•       Maintain a steady pace – walk slowly and consistently to conserve energy and reduce the risk of altitude sickness.

•       Follow acclimatization schedules – respect planned rest days to allow proper adaptation.

•       Start pass days early – cross Kongma La, Cho La, and Renjo La in the morning to avoid afternoon wind and weather.

•       Avoid alcohol at high altitude – alcohol increases dehydration and worsens altitude symptoms.

•       Report symptoms immediately – tell your guide right away if you feel headache, nausea, dizziness, or unusual discomfort.

Altitude Acclimatization Rules on the Everest Three Passes Trek

Proper acclimatization is essential for this trek, as the risk of altitude-related illness increases significantly above 3,000 meters and the route repeatedly climbs above 5,300 meters.

Key Acclimatization Stops

Namche Bazaar (3,440m)

Known as the gateway to the Everest region, Namche is the first major acclimatization stop, where trekkers spend an extra day adjusting to altitude while exploring nearby viewpoints and villages.

Dingboche (4,410m)

Dingboche provides a second essential rest day with an acclimatization hike up Nangkartshang Hill before the route heads into the higher Imja Valley and the first pass.

Gokyo (4,790m)

The day at Gokyo, including the climb of Gokyo Ri, serves as a third acclimatization point before crossing the final Renjo La pass.

The Golden Rule of Acclimatization

The trek follows the internationally recommended principle: “Climb high, sleep low.” This means trekking to a higher altitude during the day and returning to a lower elevation to sleep, helping the body gradually adjust to thinner air and reducing the risk of Acute Mountain Sickness.

Safety & Accommodation on the Everest Three Passes Trek

The Everest region has well-established trails, strong trekking infrastructure, and experienced local support systems. Throughout the journey, trekkers are supported by knowledgeable guides, marked routes, and a dependable network of teahouses that provide food, lodging, and assistance, even on the remote pass sections.

Facilities Available in Most Villages

•       Lodges and Teahouses – comfortable accommodation with basic amenities for resting and recovering after each day.

•       Health Posts – basic medical facilities in key villages for first aid and altitude-related health checks.

•       Communication Services – mobile networks and satellite options for emergency contact in many areas.

•       Helicopter Evacuation Services – emergency helicopter evacuation can be arranged from higher altitudes when necessary.

With proper preparation, guided support, and responsible trekking practices, the Three Passes Trek remains a well-managed adventure, allowing trekkers to focus on the breathtaking landscapes and cultural richness of the Himalayas.

How Transportation Works

Kathmandu to Lukla Flight

If you're travelling in the off-peak trekking months (January, February, June, July, August and December) you take a direct flight from Kathmandu to Lukla. The flight is about 35-40 minutes and you get excellent views of the Himalayas.

Manthali to Lukla Flight

During the busy trekking months (March, April, May, September, October and November), the flights to Lukla gedepartly depart from Manthali Airport in Ramechhap because Kathmandu Airport gets extremely busy. You'll leave Kathmandu at approximately 12:30am for a 4-5 hour drive to Manthali and then take a rather scenic 20-minute flight to Lukla.

Optional Helicopter Flight to Lukla

If you want a more comfortable and quicker trip you can take a direct helicopter from Kathmandu to Lukla. The helicopter will generally carry 3 to 5 people and is about USD 550 per person if you're sharing.

Essential Gear

Bringing the right gear helps you stay comfortable and safe on this challenging high-altitude trek:

• Sturdy trekking boots that are already broken in and work well on rocky, uneven, or icy trails

• A warm down jacket to keep you insulated at high altitudes

• A sleeping bag rated for cold, ideally around -15°C, but -20°C is better for the coldest nights

• Thermal base layers to keep you warm and help manage moisture

• Trekking poles to help reduce knee strain and give you better stability on steep sections

• Waterproof jacket and pants to keep you dry and shielded from wind, rain, or snow

• Crampons or microspikes for crossing the icy Cho La Pass

• UV sunglasses, sunscreen, gloves, and a warm hat

The Everest Three Passes Trek is widely regarded as one of the most difficult and rewarding treks in the Khumbu region of Nepal. It takes you over three very high mountain passes: Kongma La Pass (5,535m), Cho La Pass (5,420m) and Renjo La Pass (5,360m). You'll also pass through the well known Everest Base Camp (5,364m), Kala Patthar (5,545m) and the Gokyo Lakes (4,790m). Given the altitude, you have to plan for the huge altitude changes and allow yourself sufficient time to acclimatise.

The Everest Three Passes Trek is classed as a tough to strenuous trek. It's a long trek with lots of steep ascents and descents, rocky paths, glacier crossings and at times snow (particularly around the high passes). To actually get across Kongma La, Cho La and Renjo La you need to be in good fitness, have good stamina and be confident on the mountain paths. On some days you could be walking for 7-9 hours depending on the weather, the condition of the trail and your own pace.

One of the major problems on this trek is altitude sickness as the majority of the route is above 3,000m and quite a bit of it is above 5,000m. The key to avoiding AMS is proper acclimatisation. Your itinerary should include ample rest and acclimatisation days, gradual climbs, lots of water and a sensible walking pace. You need to be familiar with the symptoms of AMS and of course you need to heed your guide's advice during the trek.

The Everest Three Passes Trek is a tough trek but one that is very definitely achievable for the right person. You need to be fit, you need some hiking experience and you need to prepare well. A good bit of cardio, some hill and stair climbing (up and down) and some strength training prior to the trek will go a long way to building up your endurance. Having an experienced local guide and sticking to a good itinerary will go a long way to making the trek not only safer but also more enjoyable. With the right amount of preparation, acclimatisation and sheer determination you can absolutely enjoy the spectacular Himalayan scenery and the incredible mountain views that the Everest region has to offer.

Weather & Climate of the Everest Region

The high altitude of the Everest region brings massive seasonal variations. The pass conditions can change very rapidly so you do need to be well prepared.

Spring (March–May)

•       Clear mountain views

•       Blooming rhododendron forests along the trail

•       Moderate and comfortable daytime temperatures

•       One of the best seasons for crossing the passes

Autumn (September–November)

•       Stable and dry weather conditions

•       Excellent visibility of Himalayan peaks

•       Ideal trekking temperatures

•       Peak season for the Three Passes Trek

Winter (December–February)

•       Very cold temperatures, especially at higher altitudes

•       Some lodges may have limited services

Monsoon (June–August)

•       Heavy rainfall in lower elevations

•       Lush green hills and vibrant landscapes

•       Cloudy conditions with limited mountain views

•       Occasional flight delays and trail disruptions

Spring and autumns are the best times to do the three passes. The weather is more settled and the high passes are considerably safer.

Currency & Payment Information

Nepal's official currency is the Nepalese Rupee (NPR) and that's what you'll be using for all your local transactions in the Everest region.

Useful Payment Tips

•   Take enough cash from Kathmandu. It's best to withdraw and exchange it prior to your trek as ATMs are very difficult to find at high altitude.

•   There are ATMs in Kathmandu and Namche Bazaar but they are not always reliable and don't always have cash.

•   Card payments are accepted at the major hotels and agencies in Kathmandu, but you'll very rarely be able to use them in the mountain lodges.

• Remote villages are almost entirely cash based. You'll always need to have enough NPR for your food, your accommodation and your little purchases.

Nepal Arrival & Visa Information

The vast majority of international visitors can in fact get a tourist visa on arrival at Tribhuvan International Airport. It's very easy and straightforward to get into Nepal.

Available Tourist Visa Options

• 15 Days Tourist Visa: best for short trips

• 30 Days Tourist Visa: commonly chosen for the 21-day Three Passes itinerary

• 90 Days Tourist Visa: great for longer stays in Nepal

Visa Requirements

• A passport that is valid for at least 6 months from your entry date

• Recent passport-sized photos
