Overview

Pasighat to Mechuka — Siang Frontier to the Hidden Valley.

The ultimate Arunachal frontier traverse: three days from Pasighat on the Siang, up the Siyom to Aalo, then along the rough ATMYL road over Tato to Mechuka — a hidden Buddhist valley of Memba villages and gompas within sight of the Tibetan frontier. Broken tarmac gives way to landslide-prone track; carry spares, fuel and an Inner Line Permit. One of India's great border rides.
