Also known as Tsum Valley (Hidden Valley / Beyul Kyimolung) Trek.

Key facts

Region
Manaslu (Gorkha (Chum Nubri Rural Municipality))
Duration
10-13 days, 5-7 hours walking per day
Distance
130 km
Maximum altitude
3,700 m
Difficulty
Moderate — Lower maximum altitude than most Manaslu-region treks (3,700 m at Mu Gompa) and no high pass, but the valley is remote, days are long with big gorge climbs, and facilities are simple homestay/teahouse standard. Many operators grade it 3-4; side trips toward Ganesh Himal Base Camp push it toward 4.
Trek type
Homestay/Teahouse, out-and-back route
Best season
Autumn (Oct-Nov) and Spring (Mar-Apr)

Getting there
Kathmandu → Dhading Besi (paved, ~3h) → Arughat → Soti Khola → Machha Khola (rough track, ~4-6h); total 8-10h by bus, 7-9h by jeep. Return by the same road.
Altitude sickness
Moderate: the itinerary gains altitude gradually and sleeps no higher than 3,700 m, but trekkers pushing on to Ganesh Himal Base Camp (~4,200 m) or the passes toward Tibet can be affected.

Weather

Because the trek tops out at 3,700 m it stays feasible later into winter than the Manaslu Circuit, though upper-valley nights are very cold and some lodges close Dec-Feb. Monsoon (Jun-Sep) brings leeches and landslides in the lower Budhi Gandaki gorge. The valley sits in a partial rain shadow, so shoulder-season weather is relatively stable.
