Gatherings nuts, berries, mushrooms, etc. Backcountry Permits A backcountry permit is required for overnight backcountry trips in Yellowstone. They are free of charge and available at ranger stations and visitor centers. For the best information, try to get your permit from the ranger station or visitor center closest to where you begin your trip. Permits are available in advance for a reservation fee.
Camping is permitted in designated sites only.
All sites have group size limits which must be followed. This will greatly assist rangers if your party becomes lost and a search is required. Orange makers on trees and posts are used to distinguish maintained trails from game trails. Distance and directional signs are at most trail junctions. Certain trails may be hard to follow due to light use or downed markers.
