The open Mechuka valley floor along the Siyom River is why most travelers overnight here. Meadows, wooden houses, and snow peaks form a wide amphitheatre that changes with light through the day. Short walks from town and riverside camps give the best sense of the place without long treks. Clear autumn and winter mornings show the peaks; monsoon cloud can hide them for days.
