For various important reason the Upper Manaslu remains as Restricted Areas in Nepal. The first is due to close border with Tibet / China, where some trekkers might wander and enter the frontier. The next is to preserve its natural beauty of flora and fauna, allowing only limited trekkers in the best seasons of the year.The other reason is to make Upper Manaslu from Jagat village onwards, as a special area. So only trekkers in group can visit with proper guide and booking with authorized local trekking agencies.
