During the high use season, many wilderness areas in Inyo National Forest have quotas that limit the number of people allowed to enter each day. This is to help protect the wilderness value of the area. Because quotas are based on the number of people starting on the trail each day, everyone in your group must start on the entry date and trail listed on your permit. Your group cannot have more people than indicated by your permit. Click here for a list of trails and quotas in Inyo National Forest. When quotas are in effect, additional space is saved for walk-in permit requests. All unused reservation space and 40% of the quota space is available on a walk-in basis starting at 11 a.m. one day before the trip entry date. Permit requests are high on weekends, holidays and during the months of July and August. Be prepared with ideas for alternate trails in case your first choice is full.
