Manaslu Circuit with Tsum Valley Trek: 24 Days

Overview

If you’ve already looked into the standard Manaslu Circuit and thought “I want more of this, not less,” this is the trek. It adds Tsum Valley, a side valley that remained closed to outsiders until the early 2000s, to the start of the regular Manaslu route. You’ll spend close to two weeks in Tsum before you even join the main Manaslu trail, then finish the same way the standard circuit does: climbing to Larke-La Pass and dropping down the other side toward the Annapurna region.

Tibetan Buddhists call Tsum a beyul, a hidden valley set aside as a place of spiritual refuge. That’s not just branding — the valley was genuinely isolated by geography and closed to trekkers until relatively recently, and it still receives far fewer visitors than the Manaslu Circuit itself. Combined with the circuit, this becomes one of the longest, most remote, and culturally richest treks Nepal has to offer: 24 days, two river valleys, several monasteries, a base camp hike, and one high pass at the end.

Main Highlights

• Manaslu Circuit Trek — journey around Mount Manaslu, the world’s eighth-highest mountain at 8,163m.
• Tsum Valley — explore the remote “Hidden Valley of Happiness,” with its strong Tibetan Buddhist heritage.
• Traditional Himalayan villages — experience communities such as Chumling, Chhokangparo, Nile, Sama Gaun, and Samdo.
• Mu Gompa & Gumba Lungdang — visit remote monasteries that remain central to local Buddhist life.
• Ganesh Himal Base Camp — undertake a demanding side hike reaching around 4,900m, surrounded by glaciers and high peaks.
• Larke-La Pass — cross the trek’s highest point at approximately 5,106–5,160m.
• Manaslu Himalayan panorama — enjoy views of Manaslu, Himlung Himal, Cheo Himal, Kang Guru, Annapurna II, and surrounding peaks.
• Budhi Gandaki Valley — follow the river through deep gorges, forests, villages, and suspension bridges.
• Tibetan Buddhist culture — encounter mani walls, chortens, prayer flags, monasteries, and traditional mountain communities.
• Remote Himalayan landscapes — experience two distinct trekking regions with far fewer visitors than Nepal’s busiest routes.
• Spiritual Himalayan experience — combine mountain adventure with monasteries, Buddhist traditions, and culturally preserved villages.
• Exceptional photography opportunities — capture mountain landscapes, monasteries, villages, glaciers, prayer flags, and high-altitude scenery.
• 24-day immersive journey — experience Tsum Valley and the Manaslu Circuit as one continuous expedition rather than two separate treks.

Who Is This Trek Best For?

This is a serious commitment, and it suits a specific kind of trekker:

• Trekkers with previous multi-day hiking experience. You shouldn’t be learning what altitude feels like for the first time on this route.
• Travelers who want a longer, more immersive Himalayan journey, rather than ticking off one trail as fast as possible.
• People genuinely interested in Tibetan Buddhist culture and Himalayan monasteries — this is arguably the trek’s biggest draw.
• Adventure seekers looking for routes away from Nepal’s busiest trails. Both Tsum and Manaslu see a fraction of Everest or Annapurna’s foot traffic.
• Photographers, since few routes in Nepal offer this much variety in mountains, villages, monasteries, and landscape in one trip.
• Trekkers who’d rather combine Tsum Valley and Manaslu Circuit into one trip than do them separately later.
• Experienced hikers ready for a demanding high-altitude pass crossing at the end of an already long trek.

Who Should Think Twice About This Trek?

This is a 24-day, high-altitude trek with several long walking days and multiple sections above 4,000 meters. It’s not the trek to pick if you want something easy, want to keep daily walking to a minimum, or expect well-developed tourist infrastructure at every stop. Both Tsum Valley and the Manaslu region are restricted areas, so you’ll also need a licensed guide and a minimum group size of two — solo, independent trekking isn’t an option here.

Trek Difficulty & What to Expect

This is a genuinely demanding trek, and it’s worth being honest about that upfront. You’re looking at 24 days total, most of them walking, with several days running 6–9 hours. Three separate acclimatization points are built into the route — at Nile, Samagaon, and Samdo — because the trail spends a lot of time above 3,500 meters before it even gets near the final pass.

Terrain-wise, expect river gorges, forested switchbacks, suspension bridges that sway when you cross them, and rocky, sometimes icy trail near the top. None of it requires technical climbing skills or gear like ropes or crampons on a normal crossing, but it does require solid fitness, mental stamina for a long trip, and a willingness to keep going on tired legs. Nights are spent in teahouses — simple, family-run lodges with basic rooms and shared bathrooms — except in Kathmandu, where you’ll stay in a proper hotel.

Why Tsum Valley Is Special

Tsum Valley is what sets this trip apart from a standard Manaslu Circuit, and it deserves more than a passing mention. The valley sits north of the main Budhi Gandaki route, tucked against the Tibetan border and boxed in by the Ganesh Himal, Sringi Himal, and Boudha Himal ranges. Because of that isolation, it stayed largely closed to outside visitors until the early 2000s, and it still feels like it.

As the trail climbs deeper into the valley, the landscape gets steadily more alpine and the Tibetan Buddhist character of the villages gets steadily stronger. Chumling, Chhokangparo, and Nile — the villages you’ll pass through — are lived-in, working communities rather than tourist stops, with mani walls, chortens, and prayer flags marking the trail the whole way. From Nile, you’ll hike up to Mu Gompa, one of the valley’s oldest monasteries, sitting near 3,700 meters with sweeping views back down the valley. Later, from Chhokangparo, the trail climbs to Gumba Lungdang, a monastery set apart on its own hillside, before a full-day hike up to Ganesh Himal Base Camp at around 4,900 meters, where glaciers and the Ganesh Himal massif dominate the skyline.

None of this is a short detour tacked onto the Manaslu Circuit. It’s close to two weeks of trekking in its own right, and for a lot of people who do this combined trip, it ends up being the part they talk about most.

Why Combine Tsum Valley with the Manaslu Circuit?

A standard Manaslu Circuit already delivers dramatic mountain scenery, Tibetan-influenced villages in the upper valley, and the Larke-La crossing. Adding Tsum Valley on the front makes the trip considerably longer, but also considerably more varied — you get two distinct regions instead of one.

If your goal is simply to complete the Manaslu Circuit, you don’t need Tsum Valley. But if you want the fuller picture of this corner of Nepal — more culture, more monasteries, more variety in landscape — combining the two is worth the extra time.

Crossing Larke-La Pass

Larke-La is the trek’s final and biggest physical test. Sources put its elevation at around 5,106 to 5,160 meters depending on survey — either way, it’s the highest point of the journey by a wide margin, and it comes near the very end of a 24-day trip, when you’ll already have a lot of walking in your legs.

The crossing runs from Dharmasala toward the pass itself before a long descent to Bimthang, and it’s a full day out on the trail — typically 7–8 hours, starting early to beat the afternoon weather that tends to roll in at altitude. Conditions can shift quickly up there: cold temperatures, wind, occasional snow underfoot, and noticeably thinner air all make this day harder than anything lower on the route. It’s not technical, but it is demanding.

The payoff is a wide Himalayan panorama from the top, with Himlung Himal, Cheo Himal, Kang Guru, and Annapurna II all visible on a clear day. Because this is one of the longest and highest days of the whole trek, the itinerary builds in real acclimatization time beforehand — pacing, hydration, and rest in the days leading up to it matter more here than almost anywhere else on the route.

Best Time to Trek

Spring (March–May) and autumn (September–November) are the two recommended windows. Skies tend to be clear, temperatures are moderate rather than extreme, and visibility for the mountain views is at its best.

Winter (December–February) is cold, and snow on the higher sections — including around Larke-La — makes the trek harder and sometimes forces route changes. It’s doable for well-prepared, cold-tolerant trekkers, but it’s not the easy option.

Monsoon season (June–August) brings heavy rain, muddy trails, and leeches at lower elevations, along with a higher chance of flight delays into and out of Kathmandu. Most operators, including us, don’t recommend this window for this particular trek.

Altitude & Safety

This trek spends significant time above 3,500 meters, and the route above 4,000 meters isn’t brief — you’ll be up there for several days in a row before the pass. Three acclimatization points are built into the itinerary for exactly this reason: a rest hike to Mu Gompa from Nile, a rest day in Samagaon (with the option of a hike toward Manaslu Base Camp or Birendra Lake), and a side hike to Rui La near Samdo.

Standard high-altitude precautions apply throughout: drink plenty of water, ascend gradually, and tell your guide immediately if you notice headaches, dizziness, nausea, or unusual fatigue. Guides on this route carry basic medical kits and are trained to recognize altitude sickness early, but the acclimatization schedule itself is your best protection — skipping or rushing it is the most common reason treks like this run into trouble.

Permits Required

Because both Tsum Valley and the Manaslu region are restricted areas, you’ll need several permits, all of which we arrange as part of your booking:

• Tsum Valley Restricted Area Permit — required for the Tsum section, separate from the Manaslu permit below.
• Manaslu Restricted Area Permit (RAP) — covers the controlled section of the Manaslu Circuit itself.
• Manaslu Conservation Area Permit (MCAP) — for the protected zone around the Manaslu massif.
• Annapurna Conservation Area Permit (ACAP) — required once the trail exits into Annapurna Conservation Area territory near Dharapani, at the end of the trek.

A TIMS card isn’t required on this route, since the restricted area permits cover that function. Permit costs and rules change from year to year, so we confirm current pricing with you directly at the time of booking.

A Day in the Life

Days on the Manaslu and Tsum Valley trek change dramatically as you move from lower river valleys into high Himalayan terrain. In Tsum Valley, mornings often begin quietly in a simple teahouse before you head out through villages surrounded by mani walls, prayer flags, forests, and mountain scenery. The pace is steady rather than rushed, with time to stop at monasteries, talk with local people, and take in the landscape around you.

As you move deeper into Tsum, the environment becomes increasingly alpine. A day might involve climbing toward Mu Gompa, following narrow mountain trails, or making the demanding hike toward Ganesh Himal Base Camp, where glaciers and the surrounding peaks dominate the view. By evening, you’ll return to a basic teahouse, enjoy a warm meal, and settle into the quiet rhythm of life in one of Nepal’s most remote valleys.

Once you join the Manaslu Circuit, the days become more focused on altitude and mountain scenery. You’ll walk beside the Budhi Gandaki River, cross suspension bridges, pass through Tibetan-influenced villages, and gradually climb toward Sama Gaun and Samdo. Acclimatization days aren’t wasted time here — they’re an important part of preparing for the higher sections ahead.
