Lumba Sumba Pass Trek is part of the Great Himalayan Trail (GHT) which connects two trekking regions of Kanchenjunga and Makalu in eastern Nepal. This trek is a less-visited trek in Nepal because of the extreme remoteness and it is possible only with a camping trek. Himalayan Wander Walkers organize Lumba Sumba Trek by providing a veteran camping trek crew to make your dream trek a real Himalayan trip.  This trek needs really good preparation. The best time to do Lumba Sumba pass Trek is from April to May in spring and from late September to mid-November in autumn. Every year during November, the Futuk festival is celebrated in Olangchung Gola.

Although this trek is challenging the rewards are incomparable with other treks. This trek offers you the breathtaking vistas of giant mountains including the 8000s meters Kanchenjunga (8,586m) in the east and Makalu (8,463m) in the north. Besides mountain views, you will also get in touch with the Buddhist monasteries, the authentic culture of highland people, and the traditional villages of Olangchung Gola. This area is also home to snow leopards and rare red pandas. The pass Lumba Sumba (5177m) itself is a scenic viewpoint from where you will view the Makalu range and Kanchenjunga range extending from eastward to westward. 

Route of Lumba Sumba Pass Trek:

Lumba Sumba trek route starts by taking a flight to Bhadrapur and drive to Taplethok. Your trek starts from the Taplethok, a deep valley where the Ghunsa River flows, and heads toward the west via villages like Lelep and Olangchung Gola (one of the highlights of the trek). After spending a full day in Olangchung Gola, the route gets rough and wild where you will traverse the high pass of Lumba Sumba (5117m). Then the descending trek will enter the Makalu Barun National Park. You will pass through some cultural monuments like Chortens, monasteries, and Mani walls on the trekking route which are built to accumulate merits. Then slowly the altitude drops down and you will finish your trek at Num and drive to Tumlingtar. The next morning take a flight to Kathmandu.
