The Helambu Sherpa of Nepal, numbering approximately 11,000 people, are Engaged yet Unreached. They are a Tibetan-descended people who migrated from Kyirong to Helambu 4-5 centuries ago, settling mid-altitude ridges between 2,000 and 3,500 meters rather than the high valleys favored by Sherpas, practicing Nyingma Buddhism blended with ancestral animism. They mostly adhere to Tibetan Buddhism and Hyolmo is their primary language.
