Since Norgay Tenzing became the first Sherpa to reach the top of Everest in 1953 with Sir Edmund Hillary, Sherpa men have been involved in many of the record-breaking expeditions to scale the world's highest peaks.
Sherpa women, on the other hand, have been expected to stick to their more traditional roles, looking after the family, fields and livestock. But in 1993 Pasang Lhamu Sherpa became the first Sherpa woman to climb Everest.
Pemba Doma Sherpa climbed Everest in 2000 and now runs a tourist lodge in the Khumbu Valley. Hemlata Rai went to hear Pemba speak about her achievements – and also caught up with a group of British trekkers about to set out on a trek in the Himalayas.
