TRIP DETAILS

The Lumba Sumba Pass trek was only opened in 2012, so it is a relatively unknown trek. The trek connects the Kanchenjunga region and Makalu region via the Lumba Sumba pass, and runs through the Kanchenjunga Conservation Area and the Makalu Barun National Park in the eastern part of the country and can be done in one of two directions: starting in either Kanchenjunga or Makalu. 

The highlights of this 20-day Lumba Sumba Pass trek include the Lumba Sumba Peak (5,300m), spectacular Himalayan landscapes of the Makalu and Kanchenjunga ranges, different ethnic villages (Limbu, Sherpa, Rai, Gurung, Tamang), endangered wildlife such as the snow leopard and red panda, the base camps of Mount Kanchenjunga and Mount Makalu, and natural beauty. Due to its rugged terrain, harsh weather conditions, and remote trails, this is a strenuous trek recommended only for trekkers with prior high-altitude and wilderness experience.

Lumba Sumba Pass Trekking takes you high and beyond the massive mountain range of Mt. Kanchenjunga, listed as the world’s 3rd highest and Nepal’s second highest mountains, where originally pronounced as Kanchendzonga means five jewels, which relates to its five main peaks of Kanchenjunga mountain range located Nepal Far North Eastern belt of Himalaya close to the border Sikkim (North-East state of India) and Tibet beyond further north directions, guiding adventurers into a hidden land rarely visited by outsiders, around Holung, Walungchung, and Olangchung Gola.

As the trek progresses, crossing the Lumba Sumba Pass (above 5,160m) is the pinnacle of the journey, rewarding trekkers with awe-inspiring views of sacred peaks, vast glaciers, and untouched alpine landscapes, an experience that truly defines a Himalaya Sacred Trek and Expedition. 

This epic traverse reveals not only the raw beauty of eastern Nepal but also a profound spiritual connection to the sacred Himalayas, making the Lumba Sumba Pass Trek a once-in-a-lifetime adventure.

The walk on the sixth day is pleasing as it passes through Ulnus and Rhododendron forest for about an hour until we reach a suspension bridge. After crossing the suspension bridge, the trek passes through dense bamboo groves. The place is popular among trekkers as the habitat of red pandas. If you are lucky, we might catch sight of the red panda from the trail itself.

Day 08Trek from Olangchung Gola to Upper Langmale (3,893m, 6 hours)

Day 11Trek from Chauri Kharka to Thudam (3,500m, 7 hours)

Overnight at a tented camp. 

Day 13Trek from Yak Kharka to Chyamthang (2,229m, 6 hours)

On this day, the walk passes through a dense rhododendron forest. As there are no villages on the way, there are numerous side trails.

Arun River, Ridha Village and the road that leads to Kimathanka. After lunch, the trek is all downhill for about three hours until we reach the Arun River.

Day 14Trek from Chyamthang to Hatiya (1,595m, 7 hours)

The trail on the day passes through a rhododendron forest. The walk is easy, as the chirping of birds makes you feel refreshed.

Day 16Trek from Gola to Hedangna Gadhi (1,179m, 5 hours)

The trek passes through paddy fields on the 16th day, a sign that we are now in the lowlands. The walk is pleasing as the trail makes a short descent, but again makes a short climb.
