The Hyolmo and their hidden valley
The Hyolmo trace their ancestry to the Kyirong region of southern Tibet, and their language belongs to the Kyirong branch of Tibetic languages, close to Tibetan but not the same. For centuries Tibetan Buddhists called this region Yolmo, and Hyolmo lamas established gompas in its villages. Some families were hereditary lamas, and the village temples, known locally as ghyang, gave villages such as Tarkeghyang and Melamchi Ghyang their names.
Helambu was never on a great trade road the way Kerung was, but it was close to Kathmandu, and that shaped its history. Hyolmo traders and workers went to the city, and city people came up for pilgrimage and later for trekking. Outsiders sometimes called the Hyolmo the Helambu Sherpa; the Hyolmo themselves prefer their own name. Today they are one of Nepal's officially recognised indigenous nationalities, with communities also in Kathmandu, Darjeeling, Sikkim and abroad.
Modern Helambu also carries water for Kathmandu. The Melamchi Water Supply Project takes water from the Melamchi river through a long tunnel to the capital, a scheme planned for decades and opened in 2021, then damaged by the flood that June. For trekkers, the region is a chain of Hyolmo villages where you can sleep in family lodges, visit gompas, and eat apples from trees planted by people who still farm the steep slopes.
