The Manaslu Tsum Valley Trek is an amazing 19-day trekking journey in Nepal. It combines two incredible areas: the peaceful, hidden Tsum Valley, often known as the “Hidden Valley of Happiness”, and the wild trails of the Manaslu Circuit. This long-distance trek lets you see traditional Tibetan-Buddhist villages, ancient monasteries, and giant snowy mountains. The entire trip takes place beneath Mount Manaslu, which is the eighth-highest mountain in the world at 8,163 meters.
This is a strenuous high-altitude trek. You will hike 5 to 7 hours on most days on steep, rocky trails, with shorter days as you gain altitude and a long 8-9 hour day over Larkya La. The hardest part of the trip is climbing over the famous Larkya La Pass, which sits at a freezing 5,106 meters above sea level. To keep you safe from altitude sickness, our itinerary includes a rest and acclimatization day in the village of Samagaun (3,530 m) so your body can adjust to the thin air. Along the way, you will eat and sleep in local mountain lodges called teahouses.
Because the trail lies near the Tibet border, Nepal has strict trekking regulations. Since March 22, 2026, Nepal no longer requires a minimum of two trekkers to issue a restricted-area permit, so a single traveler can now apply. All other rules still apply: independent trekking is not allowed, and you must book through a registered Nepali agency like HC Treks and travel with a licensed guide.
