Lumba Samba which means New place in Sherpa native language and also it is a new trek route for Nepal trekking introduced by Trekking Agencies’ Association of Nepal (TAAN) in 2012. Lumba Sumba Peak (5200m) is the major attraction of this route and is in The Great Himalayan Trail. It is also popular as route of Bhotkhola or Upper Arun river and inhabited by Bhote which offers some of the most spectacular Himalayan landscapes.

The Following Is Designed to be a Rough Guide to help you select the trek that suits you best.


More remote country, often camping in the wild, the occasional 7 or 8 hour day (camp to camp) but not more than 5 days consecutive walking. Altitude gains of up to 600m. a day.


Up to 9 days consecutive walking including high passes up to 4500m. (With snow covering), but more typically on passes of 3650-4300m. Again, occasionally a 7 or 8 hour day, but usually 5 or 6 hours. A long way from any road!

Challenging / Strenuous

Only one of our treks, "A Himalayan Summit" fully merits this grade. This is purely on account of its altitude, 6000m. Given the time for acclimatization, this is well within the grasp of the fit and healthy.
