Since Manaslu trek falls within the restricted area, special restricted area permit along with the regular permits are required for this trek. In addition, there is a requirement from the trekking authorities of Nepal that Manaslu trek will be allowed access only if there are at least two travelers on a tour accompanied by a trekking guide or a porter provided that the trekker books his or her trip through a registered trekking agency. However, the average group size varies depending on the agencies, anywhere between 4 and 12.
