Lumba Sumba Pass Trek – Remote Eastern Nepal Adventure

The 19-day Lumba Sumba Pass Trek connects the Kanchenjunga and Makalu regions of eastern Nepal. Cross the 5,177-meter Lumba Sumba Pass, explore remote villages like Olangchung Gola and Thudam, and enjoy spectacular Himalayan views, pristine wilderness, and authentic local cultures. Ideal for experienced trekkers seeking a challenging off-the-beaten-path adventure.

  • Cross Lumba Sumba Pass at 5,177 m, where altitude sickness and reduced oxygen levels are major concerns.
  • rek through isolated areas with limited facilities, few settlements, and restricted access to emergency services.
  • Encounter snow, ice, and unpredictable Himalayan weather, particularly around the pass.
  • Stay in tents in remote locations with limited access to electricity, communication, and modern amenities.

Overview


The Lumba Sumba Pass Trek is one of the most adventurous and remote trekking routes in Nepal, connecting the Kanchenjunga region with the Makalu region through the spectacular Lumba Sumba Pass at 5,177 meters (16,985 feet). This challenging Himalayan trek takes you through untouched mountain landscapes, traditional villages, dense forests, alpine valleys, and the pristine wilderness of eastern Nepal. It is an excellent choice for experienced trekkers seeking an off-the-beaten-path adventure away from Nepal's busy trekking trails.

The highlight of the Lumba Sumba Pass Trek is crossing the high-altitude Lumba Sumba Pass, surrounded by magnificent Himalayan scenery and spectacular views of peaks in the Kanchenjunga and Makalu regions. Along the route, you will explore remote settlements such as Olangchung Gola and Thudam, experience the traditional lifestyles of eastern Nepal's ethnic communities, and discover the cultural heritage of the Limbu, Sherpa, Rai, Tamang, and other local groups.

This remote trek offers an incredible diversity of natural landscapes, from subtropical forests and pristine rivers to alpine meadows and rugged Himalayan terrain. The region is also rich in biodiversity, providing habitat for rare wildlife, including the elusive snow leopard. With limited infrastructure, challenging trails, river crossings, and long stretches through isolated wilderness, the Lumba Sumba Pass Trek requires good physical fitness, proper preparation, and previous trekking experience.

Trip Information

Your Guide and Team

Your guide, from your arrival in Kathmandu until your departure, is responsible for the success of your trip and oversees your team. Do not hesitate to ask him questions, respect his position as the team leader, and above all, follow his advice! Often, your guide is the only English-speaking member of the team. In the mountains, especially during high-altitude travels, your guide is responsible for the safety of the group. The instructions he gives and the remarks he makes to all participants must be carefully followed. The interest and safety of the trekking group must be preserved, even when it may be to the detriment of an individual member of the group.

Your Nepalese team may consist of several people, each with different responsibilities. They are:

  • The Guide Leader (Sirdar) is responsible for and the leader of the whole team and is treated with respect by all. Often, he has earned his position by starting as a porter and rising through the ranks.
  • The Assistant Guide actively helps clients under the leader’s direction and sets up camp. 
  • The Porter is the load carrier for the trekking group. As Nepal is a mountain country with few roads, porters are employed to carry loads. Compliance with regulations and common courtesy dictates the maximum weight carried and the minimum wage paid. Porters are provided with gear based on the routes they follow and with insurance for alpine treks.

Each trekker is allotted the following maximum weights per person: Lodge (tea house) Accommodations: 15 kg maximum; Tent Camping: 22 kg maximum; Expeditions/summit ascents: 20 kg maximum. The porters are given a premium wage for carrying loads over 30 kg. 

In addition, the Nepal Alpinist Club takes care to take out insurance for the Guide and porters. Specific equipment is allocated to them for crossing passes at altitude (even if wearers often refuse to put on shoes due to lack of habit).

Accommodations in Kathmandu

In Kathmandu, you will stay in a hotel. We use different hotels depending on availability. The two preferred hotels are:

  • Hotel Ramoda: Located in the heart of Thamel, this hotel is ideal for walking the bustling streets of Kathmandu. The spacious rooms all have a bathroom, air conditioning, and Wi-Fi. A fully equipped and active dining room is available for all meals, and the breakfast buffet offers a wide choice of foods. The hotel offers currency exchange, laundry services, and luggage storage.
  • Sampada Garden: Located just 20 minutes on foot from Thamel and  Durbar Square, this hotel is convenient for exploring Kathmandu. The rooms have all the necessary comforts for your stay: air conditioning, a bathroom, and Wi-Fi. Breakfasts are served as a generous buffet. The hotel provides currency exchange, laundry services, and luggage storage.

Accommodation during the Lumba Sumba Pass Trek 

For lodge accommodation, meals are prepared by the cooks of the lodge and are taken from the lodge's dining room. 

Here is a typical one-day menu: 

  • Breakfast: eggs, toast or chapati, Tibetan bread or pancakes, butter/jam, tea or coffee
  • Lunch: a main course, tea or coffee
  • Dinner: soup, main course, fruit (fresh or canned), tea or coffee
  • During the trek, tea or coffee is served with meals. Two cups per person are included.Apart from these included menus, other drinks and foodstuffs will be at your expense.
  • Water: provide tablets (Hydrochlorothiazide, Micropur, or another type) to disinfect the water you put in your water bottle, depending on the source and on the advice of your guide. It is sometimes possible to buy purified water and refill your water bottle without having to buy bottled water. You can also buy mineral water in the cities (not included in the price), but its ecological balance is poor, as you know. Also, we do not recommend it.

Preparation for the Trek

Preparing for the trek requires several months of preparation with 4- to 6-hour walks every weekend for stamina and participation in a sport that requires short periods of high exertion.

Medical check-up

Being in good health is essential to fully enjoying your Alpinist Club trip. If your last medical visit was more than four years ago, please get another general physical exam and tell your doctor the nature of your trip (climate, altitude, difficulty, etc.). The altitude also has the effect of reviving dental problems or other chronic pain, so getting a dental checkup is also prudent. If you are undertaking a high-altitude expedition, we advise you to consult a mountain medicine specialist.

Acute Mountain Sickness

This trip takes place at high altitudes, so some people may experience altitude-related discomforts like headaches, loss of appetite, and swelling of limbs. Most of these symptoms usually go away within a few days, but sometimes they can develop into a serious illness: pulmonary or cerebral edema. There are no preventive drugs for AMS. The diuretic is often effective for symptomatic relief, but you should first check with your doctor to verify that it is not contraindicated for you. Think about it before you go.

Frequently Asked Questions

In eastern Nepal, the Lumba Sumba Pass Trek is a less traveled and relatively new hiking route. It leads you through isolated and pristine areas with breathtaking Himalayan views, a variety of plants and animals, and a chance to learn about the rich local cultures.

Your safety is our top priority. We never sacrifice your safety while trekking, and all of our guides are adequately qualified and prepared to look out for our clients' safety, especially on high-adventure routes.

The Lumba Sumba Pass Trek is considered a challenging trek. Long walking days, hard climbs and descents, and traversing high mountain passes are all part of it. It is advised to have prior hiking experience and to be in good physical condition. We do not recommend this trek for beginners.

Depending on the schedule and the group's speed, the Lumba Sumba Pass Trek often takes 19 to 25 days to finish.

Trekking in the Lumba Sumba region requires a special permit known as the Kanchenjunga Conservation Area Permit (KCAP). Additionally, you must get the Trekkers' Information Management System (TIMS) card as well.

As the Lumba Sumba Pass trek is an underdeveloped route, there are limited options for tea houses and lodges.  We recommend you carry your camping gear and food. 

Spring (March to May) and fall (September to November) are the ideal seasons to complete the Lumba Sumba Pass Trek. Clear skies, consistent weather, and excellent mountain visibility during these months give you the best trekking experience. 

Since the Lumba Sumba Pass Trek will take you to high elevations, there is a chance that you could get altitude sickness. Drink lots of water, pay attention to your body's cues, and acclimate yourself appropriately. A doctor's advice is also advised before starting the trek.

While there are luxurious restrooms in the city, the Lumba Sumba Trekking area does not have the same conveniences. Typically, there are basic facilities that must be shared with other tourists.

In the more rural Lumba Sumba Trekking zone, communication services are unpredictable and heavily impacted by both climatic and topographical factors. As a result, maintaining flexibility is still necessary.
