Humla–Hilsa corridor and the Limi valleyहुम्ला–हिल्सा र लिमी उपत्यका

The Humla corridor is where trade and pilgrimage have always been the same road. Purang — Taklakot in Nepali usage, from the Tibetan Taklakhar — sits below Mt Kailash and Lake Manasarovar at the junction of Nepal, India and Tibet, and was western Tibet's great mart: Indian Bhotias from Kinnaur, Garhwal and Kumaon, Humli and Muguli traders, and the Limi villagers all converged there to load salt and wool, paying Lhasa's salt tax for the Ngari-lake routes on the spot at Rutok or Purang. From the border village of Hilsa, where the Humla Karnali leaves Tibet — Taklakot is only about 35 km away — the trail to Simikot, Nepal's highest district headquarters at 2,900 m, was the historic artery. The salt then dispersed down half a dozen Karnali valleys: from Taklakot over Lapcha La in upper Humla to Bajura and Achham, through the Nankhang valley to Jumla, from Marim toward Rukum and Jajarkot, and via Dailekh through Mugu's “Karan belt”.

The Limi valley — the villages of Til, Halji and Jang, anchored by Halji's Rinchenling monastery — preserved the old economy longest and shows both its logic and its fragility. Sealed behind the 4,940 m Nyalu La, snowbound about six months a year, its people lived from transhumant pastoralism and trade: herds grazed the Karnali and Limi grasslands in summer and Tibetan pastures in winter under customary rights that predated the border, while salt, wool and — per some accounts — gold moved south and grain moved north. Limi is famed for furu (phuru), maplewood bowls highly valued by Tibetans, carved over winter and sold in Purang along with handicrafts. The 1962 border closure ended the winter grazing rights and trade fairs, and early-1990s restrictions cut the residual cross-border grazing — amputating each limb of the old economy in turn.

The same trails carried, and still carry, Hindu and Buddhist pilgrims to Kailash and Manasarovar. Hilsa is the main Nepal-side gateway for the Kailash-Mansarovar Yatra, and when the 2015 earthquake severed the Kodari route, Indian pilgrims crossing here tripled to about 10,000 in 2016, helicopters shuttling between Simikot and the border. ICIMOD's 31,000 km² transboundary Kailash Sacred Landscape programme includes Humla.

What replaced the old complementarity is starker: people now move where salt once did. The border reopened in April 2025 after a four-year pandemic closure, and 10,955 border passes have been issued since (8,237 new, 2,718 renewals) — free year-long documents allowing 30 km of access into China, with 15–50 people applying daily. Roughly 70% of young people from Namkha and Simkot rural municipalities work seasonally in Taklakot from March–April to mid-December at about 300 yuan (≈Rs 5,800) a day, saving up to Rs 400,000 a season, while yarsagumba fetches Rs 2–2.4 million per kilogram across the line. Humla was long the last district unconnected to Nepal's road network — which is why, in practical terms, Nepal's remotest district still orbits a Chinese county town that remains closer than Kathmandu.
