The best season for the Manaslu Tsum Valley trek is October to November, with clear skies, 5 to 15 C daytime temperatures at 3,500 m, stable Larkya La pass conditions at 5,106 m, and 80 to 90 percent mountain view probability. April to May is the second best window with rhododendron blooms, warmer nights at 0 to 5 C, and 70 to 80 percent view probability. Avoid June to September monsoon with 70 percent cloud cover and December to March winter with 1 to 2 m of snow at Larkya La.
Detaillierte Aufschlüsselung
The Manaslu Tsum Valley trek combines the Manaslu Circuit with a side trip into the Tsum Valley, the sacred Buddhist valley branching east at Philim at 1,570 m. The full route covers 200 km over 16 to 21 days, reaching 5,106 m at Larkya La and 3,700 m at Mu Gompa.
October brings stable weather with dust free air, crisp 5 to 15 C days, and 80 to 90 percent view probability. Night temperatures drop to minus 5 C at 4,000 m, but teahouses have wood stoves in dining halls.
April and May bring warmer conditions with daytime highs of 10 to 18 C at 3,500 m and rhododendron forests blooming at 2,500 to 3,500 m from late March to mid April. Mountain views run 70 to 80 percent in April, dropping to 60 to 70 percent in May as pre-monsoon cloud builds.

Was beeinflusst die Antwort
Larkya La pass crossing is the biggest constraint. The 5,106 m pass has 1 to 2 m of snow from December to March, blocking 80 percent of departures. October and April to May have reliable crossings with 85 to 95 percent success. June to September has 40 to 55 percent success.
Permit quotas shape the choice. The Manaslu restricted area permit caps October departures at 300 trekkers per week, filling 8 to 10 weeks ahead. April and May have 40 to 60 percent availability 4 weeks ahead. December to February has no quota pressure.
Tsum Valley access matters. The side valley branches at Philim and reaches 3,700 m at Mu Gompa, with crossing viable year round except for January to February when snow blocks the upper valley trails. Combine Tsum with the main circuit in October or April for the best weather.
Buchungstipps
Book October departures 10 to 12 weeks ahead to secure the Manaslu restricted area permit quota and Dharmasala teahouse bookings at 4,460 m. Confirm the permit is issued under your name 7 days before departure.
Book April departures 6 to 8 weeks ahead for moderate availability and warmer conditions. Pack a four season sleeping bag rated to minus 10 C since April nights still drop below freezing at 4,000 m.
For December to February departures, book only with operators offering Larkya La weather monitoring and a backup Annapurna Circuit itinerary. Carry crampons since ice covers the pass approach from late November.
Vergleich mit Alternativen
The Manaslu Circuit without Tsum Valley costs $1,300 to $1,900 for 14 to 16 days and follows the same October and April to May windows. The Annapurna Circuit costs $1,200 to $1,800 for 12 to 16 days and offers more teahouse backup, with November as its peak month.
Choose October Manaslu Tsum for the best views and stable Larkya La. Choose April to May for warmer conditions and rhododendron blooms. Choose Annapurna Circuit for a similar altitude route with more flexible season windows.
Häufige Fehler zu vermeiden
Do not book a September departure in the first two weeks. Monsoon tail clouds persist through September 15 to 20, dropping view probability to 50 to 60 percent and increasing landslide risk on the Soti Khola road approach.
Do not attempt Larkya La in winter without crampons and a guide. The marked trail disappears under snow from December, and 3 to 5 trekkers per season require rescue.
