Yes – Manaslu is a restricted area. You must trek with at least one licensed guide and a minimum of two trekkers in a group. You’ll need three permits: Manaslu Restricted Permit, Annapurna Conservation Area Permit (ACAP), and Manaslu Conservation Area Permit (MCAP).

The Larkya La Pass (5,160 m / 16,930 ft) is the highest and most challenging point. The climb is long and steep, and weather/snow conditions at the pass can be unpredictable, especially in early or late season.

The best seasons are autumn (September–November) for clear skies and stable weather, and spring (March–May) for rhododendron blooms and warmer temperatures. Winter is possible but very cold and snowy at the pass; monsoon (June–August) is not recommended due to heavy rain and landslide risk.

It is considered moderately strenuous to strenuous. It’s similar in difficulty to the Three Passes Trek in Everest region but slightly harder than the classic Everest Base Camp or Annapurna Circuit routes because of the higher pass, longer continuous climbing days, and more remote teahouses with basic facilities. Previous high-altitude trekking experience is strongly recommended.
