Helambu is a Buddhist highland circuit east of the Kathmandu Valley, home to the Hyolmo Sherpa people, a distinct ethnic group with Tibetan roots who have lived in villages like Tarkeghyang (2,560 m) and Melamchi Gaon (2,550 m) for centuries. Tarkeghyang, the largest Hyolmo settlement on the circuit, has a working gompa, colourful prayer flags, carved stone chortens and a traditional weaving industry. Melamchi Gaon, a short walk farther, is smaller and quieter, with views down the Melamchi Khola valley.
The circuit connects Helambu to the Langtang region via the Tharepati ridge (3,600 m), which gives a clear view west to the Langtang Lirung massif (7,227 m) on a fair day. This is the cultural counterpoint to the pilgrimage approach to the lakes: Buddhist gompa architecture, mani walls and a community that has changed slowly. Ask your guide before entering gompas, and walk clockwise around mani walls.
