Permits Are Limited
To protect the wilderness and visitors’ experiences, the number of permits issued for each area is limited. Popular areas such as around Cascade Pass, along Ross Lake, on Copper Ridge, and at Thornton and Monogram Lakes can be very busy during the height of summer, and permits can fill quickly. The busiest climbing areas are: Sulphide Glacier, Boston Basin, and Eldorado cross-country zones. To maximize your chance of obtaining a permit and finding solitude, visit these areas midweek or after Labor Day, and have a backup itinerary or climb in mind if your first-choice area is already full. Ask a ranger for less busy alternative areas to visit. There is always somewhere to go.
Why do I need a permit?
Backcountry permits protect your wilderness experience by preventing overcrowding at camps or climbing routes, and protecting natural resources so that all visitors, including future generations, can enjoy them. Permits also serve an important safety function in the event of an emergency or wildfire, and allow managers to gather data important for decision making.
