Manaslu

The Manaslu Circuit Trek is rated moderate to strenuous/difficult, challenging trekkers with its high altitude (peaking at Larkya La Pass 5,106m), varied rugged terrain (river valleys, scree slopes, glacier crossings), long daily walking hours (6-8 hrs), remote wilderness, and unpredictable weather, demanding good physical fitness, mental resilience, and proper acclimatization for the risk of AMS. It's considered harder than EBC or Annapurna due to its remoteness, technical sections, and harsher conditions, but rewarding for experienced adventurers.
