Which is the Peak Season for the Manaslu Circuit Tsum Valley Trek?
The peak trekking season for the Manaslu Circuit with Tsum Valley Trek is Autumn (September to November). During this period, the monsoon rains have receded, leaving behind clear skies, stable weather, and breathtaking mountain views. Spring (March–May) is also popular, thanks to blooming rhododendrons, moderate temperatures, and quieter trails.
Peak season brings the advantage of well-established tea houses, available guides, and safe trail conditions, making it ideal for first-time trekkers. However, this also means more trekkers on the trails and slightly higher accommodation costs.
Is Winter Recommended for the Manaslu Circuit with Tsum Valley Trek?
Winter trekking in the Manaslu region (December to February) offers a completely different experience compared to other seasons, quiet trails, crisp air, and stunning snow-covered landscapes. But the big question is: Is winter a recommended time for the Manaslu Circuit with Tsum Valley Trek?
Winter is not recommended for most trekkers, especially beginners.
However, it can be recommended for highly experienced trekkers who are prepared for extreme cold and challenging trail conditions.
Why Winter Is Not Ideal for Most Trekkers?
Winter in the Manaslu region is harsh, especially above 3,500m. Places like Samagaun, Samdo, Dharmasala, and Larkya La Pass (5,160m) get extremely cold, often dropping to –15°C to –20°C at night.
Some of the key challenges include:
- Heavy snowfall that can block or hide trails
- Larkya La Pass often becomes impassable due to ice and snow
- Limited tea house availability in higher villages
- Shorter daylight hours, making the trek slower and riskier
- Increased chance of frostbite and altitude sickness
- Difficulty navigating, as snow often covers trail signs
Because of these conditions, guides and local authorities often discourage winter attempts, especially for trekkers with little high-altitude experience.
When Can Winter Be Recommended?
Despite the challenges, winter can be rewarding if you meet certain conditions:
- You have previous experience above 4,500m in winter conditions
- You hire an experienced Manaslu-certified guide
- You are well-prepared with winter gear (down jacket, crampons, thermal layers, proper boots)
- You enjoy solitude and snow-covered Himalayan landscapes
- You understand the risks and have a flexible itinerary
Weather and Trail Conditions

The weather on the Manaslu Circuit with Tsum Valley Trek changes a lot as you go higher. You start in warm villages at 700–900m and climb up to the snowy Larkya La Pass at 5,160m. Along the way, you’ll pass through different climates, so knowing the seasons helps you stay safe and enjoy the trek.
Seasonal Temperatures and Precipitation
- Spring (March–May) brings gradually warming temperatures and stable weather. Mornings are usually crisp, afternoons pleasant, and evenings chilly. Rainfall is low in early spring but becomes more frequent from late April onward. Higher sections may still have snow from winter.
- Autumn (September–November) is the most reliable season with minimal rainfall, clear skies, and mild daytime temperatures. This is the period when visibility is at its best, offering panoramic views of mount Manaslu, Himalchuli, Ganesh Himal, and the surrounding peaks.
- Monsoon (June–August) has the heaviest rainfall. Lower sections such as Soti Khola, Jagat, and Philim receive frequent showers, and trails become muddy and slippery. Rising river levels make crossings more challenging. Cloud cover also reduces visibility in Tsum Valley and around Samagaun.
- Winter (December–February) sees freezing temperatures, especially above 3,500m. Snowfall is common at Samdo, Dharmasala, and Larkya La Pass, making the high route more technical. Daylight hours are shorter, and conditions can change quickly.
River Crossings and Water Levels
Many sections of the Manaslu trail run alongside the Budhi Gandaki River. In monsoon, water levels rise significantly, making suspension bridges essential and sometimes risky due to heavy winds and overflowing streams. Small side streams from melting snow in spring may also require careful crossing.
In winter, riverbanks can become icy, increasing the risk of slips when approaching bridges.
Challenges at Larkya La Pass
The situation at Larkya La Pass, the trek's highest and most difficult point, are largely seasonal:
- In Spring and Autumn: The pass is usually clear, with well-defined trails and manageable wind conditions. These are the most recommended times for crossing.
- In Winter: Snow accumulation can hide trail markers, and ice makes the ascent and descent extremely slippery. Strong winds also make the crossing dangerous.
- In Monsoon: Rain, fog, and unstable ground conditions significantly increase risk, and visibility is usually poor.
Because of these challenges, trekkers often begin the ascent to Larkya La before sunrise, allowing enough time to cross safely before afternoon winds pick up.
