Trekkers in Nepal are allowed to trek as FIT (Free Individual Trekker) or in a group of various sizes. However, there are certain trekking regions known as 'Restricted Areas' that are highly regulated by the Government of Nepal, and hence FITs are strictly forbidden. Trekking in these areas is allowed only upon acquiring a permit from the Department of Immigration.
Interested trekkers should contact the authorized trekking agencies who then can apply for permits (on behalf of trekkers) at the Department of Immigration fulfilling all the necessary formalities. Trekkers should be trekking in a group (of a minimum of two persons) accompanied by a licensed trekking guide. Individual trekkers cannot apply for the permit.
There are different rates (trekking Permit fees) applicable for different routes to acquire the Permits. Visit the link for detail. Permit fees are quoted in US dollars but payable in Nepali Rupees. A trekking permit is not issued beyond the visa expiration date. Hence, trekkers must have valid visas for a sufficient number of days covering their trekking schedule.
