The Limi Valley Circuit is a classic loop in Humla, the most remote district of far-west Nepal, on the Tibetan border. Starting and finishing at Simikot airstrip (2,985 m), the route follows the Karnali River north via Dharapori, Kermi, Yalbang, Tumkot and Yari, crosses Nara La (4,560 m) to Hilsa, then heads east into the Limi Valley through Manepeme, Til, Halji and Jang. It returns over Nyalu La (5,001 m, the high point of the route) and descends via Salli and Kermi back to Simikot.
The circuit is well documented as a 15 to 20-day trek (Great Himalaya Trail, West Nepal) and is known for its preserved Tibetan Buddhist culture (Rinchenling Gompa in Halji), wildlife and high passes. Terrain is trail and old trade route, mostly between 3,000 and 5,000 m. There is no technical climbing, but there are several high-altitude passes and very limited rescue options.
Access: trekking in Humla requires a restricted area permit, arranged through a licensed Nepali trekking agency.
GPX: Simikot–Hilsa and Salli–Simikot from the Great Himalaya Trail GPX (2023). Limi section routed on OSM trails through GHT waypoints, with one short approximate section between Jang and Tholing.
