The Lumba Sumba pass trek is one of Nepal's best-kept secrets. This trek explores the remote Kanchenjunga and Makalu regions in the eastern Himalayas of Nepal. It is a camping trek, so the trekkers have to be self-sufficient. This 21-day long trek is an ideal package for anyone looking for an untouched and unheard trekking route in the Himalayas. 

We, Nepal Nirvana Trails provide full support during the Lumba Sumba Pass camping trek in Nepal. Our expert on-field team will make sure you are traveling safely and enjoying every moment in the mountains. We will take care of all the accommodation and meals during the trek, allowing you to fully immerse in the journey. 

The Lumba Sumba pass trek was opened in 2012. The trail follows a section of the Great Himalayan Trail (GHT). The Lumba Sumba pass connects Kanchenjunga Conservation Area with Makalu Barun National Park. Because of no tourist infrastructure and offbeat terrain, only a handful of trekkers have explored this adventurous route. 

Trekking from sub-tropical forests, the trail ascends to high grasslands and alpine zones. You will rarely see any fellow trekkers on the way. The highest point of the trek, Lumba Sumba Pass, is located at 5,177 meters (16,985 ft). Likewise, the Tamor and Arun river system is another highlight of Lumba Sumba pass trekking. As you trek from one zone to another, you will get to witness many different landscapes. 

During the trek, you will pass via verdant valleys, rocky gorges, and beautiful villages. Limbus, Sherpas, Rais, Gurungs, Magars, and Tamangs are the major inhabitants along the Lumba Sumba pass trail. The locals are quite friendly and welcoming, like any other Himalayan trail. The Lumba Sumba Pass trek is equally rich in cultural heritage. There are many chortens, stupas, and prayer flags on the way. Likewise, the interactions with locals are one of the precious parts of the trek. 

Mountain views and wildlife during the Lumba Sumba pass trek in Nepal

During the Lumba Sumba pass trek, you will get to see stunning views of the third-highest mountain in the world- Mount Kanchenjunga (8586m.|28169ft.) & the fifth-highest mountain in the world- Mount Makalu (8481m.|27825ft.). Similarly, you will see many other mountains like Sarphu Himal (6433m.|21105ft.), Sarphu II (6328m.|20761ft.), Sarphu III (6158m.|20203ft.), Nangma (5201m.|17063ft.), Marson (6220m.|20406ft.), Senup (6265m.|20554ft.), Ghanlung Himal (5757m.|18888ft.), etc. Likewise, around Olangchung Gola village (3208m.|10524ft.), there are many alpine lakes where you can unwind and rejuvenate. 

As the Lumba Sumba pass trail winds through two highly protected areas in Nepal, you will get to see diverse species of flora and fauna. The rhododendron and pine forests, rushing rivers, and cascading waterfalls make the lower part of the trail bloom with various vegetation. The region is home to many wildlife and birds, including the exotic snow leopard and red panda. 

Extend the Lumba Sumba pass trek to Kanchenjunga Base Camp and/or Makalu Base Camp

Usually, trekkers embarking on the Kanchenjunga Circuit Trek have the opportunity to discover the Kanchenjunga Base Camp, while those undertaking the Makalu Base Camp Trek can explore the Makalu Base Camp. As you are already touching these two regions on Lumba Sumba pass trek for 21 days, you can extend the trek to either or both base camps if you have a few extra days to travel.

Lumba Sumba pass trek difficulty

The Lumba Sumba pass trek is one of the most strenuous treks in Nepal. The off-the-beaten-path, unpredictable weather, long walking hours, and high altitude make this trek quite challenging. The path of the Lumba Sumba pass trek takes adventurers through the distant and secluded areas of the Kanchenjunga and Makalu regions. The trekking route involves long steep ascents and descents. The trail is mostly rugged and uneven.

Each day, you will cover 9 to 11 kilometers (5 to 7 miles), which means a minimum of 6 hours of walking. Similarly, the challenges are compounded by the remote nature of the area and the absence of tourist infrastructure. You will be exploring the rural communities, so you cannot expect any modern facilities. You not only have to be well prepared for this trek physically and mentally, but proper packing is also important. 

Altitude sickness during the Lumba Sumba Pass trek

The Lumba Sumba Pass trek starts from Sekathum (1650m.|5413ft.) and ascends to the top of the Lumba Sumba Pass at 5,177 meters (16,985ft.). Due to the significant gain in altitude, the trek carries the potential for altitude sickness. However, this trek does not see any sudden drastic change in elevation, and you will get ample time to adjust to the elevation before trekking beyond 5,000 meters (1,6404ft.). 

By adopting preventive measures and being aware of altitude sickness symptoms, you can avoid altitude sickness altogether on this trek. These are a few symptoms of altitude sickness- headache, difficulty in breathing, insomnia, vomiting, loss of appetite, etc. Keep yourself hydrated while trekking & take proper rest and have plenty of food to avoid altitude sickness. 

Our Lumba Sumba pass trek itinerary has adequate acclimatization days to let you rest and recover as your trek further. In case you observe any of these symptoms, make sure to inform your guide right away. Our guides have received proper training to manage medical emergencies in mountainous settings, ensuring that you are in capable and secure hands.

Can I do the Lumba Sumba Pass trek as a beginner trekker?

We do not recommend Lumba Sumba pass trek of 21 days to individuals who are trekking for the first time. This trek is very demanding in all manners.

Useful Info

Best time to do Lumba Sumba pass trek

The best time to do the Lumba Sumba Pass camping trek in Nepal is from March to May (spring) and September to November (autumn). These months see less instability in weather along with lower chances of precipitation, which makes trekking smooth. Likewise, the pleasant climate and long daytime make trekking fantastic. The trail bloomed with seasonal flowers and plants. And the birds and wildlife also thrive. 

Winter (December to February) and summer/monsoon (June to August) are also favorable times for Lumba Sumba pass trek. The trail condition is not good, and the weather is very unpredictable, making trekking tougher than it already is. However, we may arrange the trek at the start or end of the offseason. So, if you wish to do the Lumba Sumba Pass trek in the off seasons, contact us.

Accommodation and meals during the trek

Lumba Sumba Pass is a camping trek, so you will spend the nights in sturdy alpine tents provided by our company. At the start and end of the trek, we may spend a few days in tea houses (as per availability). Our company will provide sleeping, dining, kitchen, and toilet tents. The team will take care of setting up the tent at all overnight places. For additional comfort, get a nice sleeping bag. One sleeping tent will be shared between two trekkers. 

The meals as well are cooked by our team. You will be trekking with a cook and kitchen staff who will take care of your meals during the trek. We will make the menu as per your liking and make sure all the ingredients are hygienic and well-sourced. Dal bhat, thukpa, momos, burgers, pasta, noodles, soups, porridge, etc will be our staple. Likewise, we provide toast, eggs, sausages, oats, etc for breakfast with a range of beverages. 

Travel Insurance

The Lumba Sumba Pass trek takes you to a very secluded part of the Himalayas that is not connected to any town or city. You either have to walk to take a helicopter flight because there are no roadways. Trekking in a region like this requires travel insurance to protect you during medical or any kind of emergency. 

We ask our guests to get travel insurance with emergency air evacuation (up to 5,000 meters) and medical bills for the Lumba Sumba Pass trek of 21 days. You are also free to cover international flights and your luggage in the travel insurance. 

Airport pickup & drop off

Airport pick-up and drop-off is a complimentary service in our Lumba Sumba Pass trek package. Our team members will be present at the Tribhuvan International Airport according to your flight's arrival schedule to greet you. They will assist you with luggage and any questions you may have before we meet during our welcome dinner. Similarly, when the trek concludes, our team will accompany you to the airport and offer you a final farewell.

Charging & Communication

To keep your electronic device charged during the trek, we recommend you carry solar chargers, power banks, and spare batteries for backup. In some villages, you may get charging facilities for a few dollars, but it's better to not rely on this.  

Similarly, to stay connected with your loved ones, get a tourist sim in Kathmandu and use data. The network may fluctuate as you trek, but you will get ample opportunities to share your journey with your friends and family. 

Personal expenses

Our Lumba Sumba Pass trek cost covers all your accommodation and meals during the trek along with expenses of our crew, permits, overnight stay in Kathmandu, and taxes. However, you have to budget additional money to buy extra food and beverages, souvenirs, etc. Likewise, you should also budget money to tip our guides, porters, and drivers. 


Each trekker has a 10 kg weight limit, along with that, you can carry an additional 5 kg day pack on yourself. If you think your luggage is going to be heavy, you can extend your luggage limit by paying extra money. If you are left with any suitcase after packing, you can store it in your hotel's locker room or at our office for the trek duration.
