Manaslu, located in the Province 4 of Nepal, is a popular trekking destination offering stunning mountain scenery and challenging trails. Accessibility is limited, requiring a multi-day trek and acclimatization to high altitudes. Guided treks are highly recommended due to the remote location and potential for altitude sickness. The best time to visit is during the pre-monsoon (March-May) and post-monsoon (September-November) seasons, as weather conditions are more favorable. Expect to spend approximately 12-20 days on the Manaslu Circuit Trek, with costs varying widely based on the level of service, permits, and gear, typically ranging from $1,000 to $3,000+. Solo trekking is possible with the necessary permits and experience, but not advised, especially for inexperienced trekkers.
