Permits & Formalities
A trek to a restricted area must be arranged as a fully equipped organised trek through a trekking agency. The trekking agency arranges the permit through a series of applications, guarantees and letters, a process that requires about two weeks and can be started only 21 days before the arrival of the group. You may not trek alone; there must be at least two trekkers in each group. For some areas there is a limit to the number of trekkers per season. There is no system of advance reservation, and no clear indication of what will happen if the quota is reached the day before you make an application.
Each group is assigned an "environmental officer" who will accompany it during the trek. Despite the fancy name, what you will get is a Nepalese policeman who you must equip, insure and take on the trek. The liaison officer is supposed to handle all the formalities with police and government offices en route.
