Cougar Island — Ross Lake National Recreation Area

Cougar Island Campground offers basic backcountry amenities. Most sites feature fire rings for campfires, and there are primitive toilet facilities available. The campground does not provide potable water, so visitors must bring their own water or have a filtration system for lake water. There are no garbage services, so pack-out all trash. Sites are situated to provide privacy, with some directly on the lakeshore while others are tucked slightly inland among the trees. The natural setting is the primary amenity, with beautiful lake views and surrounding wilderness.

Cougar Island Campground is a backcountry site located on Ross Lake in the Ross Lake National Recreation Area. Access is primarily by boat, either by bringing your own watercraft to Ross Lake or arranging water taxi service. The main access points are via Hozomeen from the north (accessible from Canada) or from Ross Lake Resort on the south end, which can be reached from North Cascades Highway. Many visitors use the Ross Lake water taxi service to reach the island. Since this is a backcountry destination, plan your water transportation in advance.

Yes, a permit is required for camping on Cougar Island. The campground operates under the Ross Lake National Recreation Area's backcountry permitting system. This system ensures you'll have a reserved spot and helps manage visitor numbers to protect the wilderness experience. Permits can be obtained through the National Park Service, specifically the North Cascades National Park Complex which administers Ross Lake. It's advisable to secure permits well in advance, especially for summer weekends and holidays when demand is highest. Contact the Wilderness Information Center for current permit information and reservation procedures.

The optimal time to camp at Cougar Island is during the summer months (late June through early September) when weather conditions are most favorable and access is reliable. Peak season typically runs from July through August when temperatures are warmest. During this period, the campground can get busy, so securing permits well in advance is recommended. Late spring and early fall can offer more solitude but may bring cooler temperatures and increased precipitation. Winter camping is not advised due to difficult access and harsh conditions.
