About

Cougar Rock Campground is situated in a steep river valley on the southwest side of Mount Rainier National Park, about 2 miles uphill from Longmire Historic District. At 3,180 feet elevation, the campground is surrounded by majestic old-growth forest that provides privacy for campsites while offering access to some of the park's premier destinations. The Nisqually River runs across the main road from the campground, and the facility includes 179 total sites organized into loops A through E and R, with 133 sites available for reservation and 46 first-come, first-served. The location is ideal for exploring the park, with Paradise less than 15 minutes away, where visitors can experience spectacular wildflower displays through July and August, along with miles of hiking trails and commanding views of Mount Rainier. The Wonderland Trail, a strenuous 93-mile route that encircles the mountain, is accessible directly from the campground. Nearby waterfalls including Carter Falls, Madcap Falls, and Comet Falls are within moderate hiking distance. The campground features an amphitheater where interpretive programs are held seasonally, helping visitors learn about the park's natural and cultural history. Due to the steep valley location and winding roads, RV access is limited to vehicles 35 feet or less, with only a limited number of pull-through sites available.

Directions

Located 14 miles east of Ashford, Washington, on State Route 706/Paradise Road, about 2 miles uphill from Longmire. Enter Mount Rainier National Park through the Nisqually Entrance in the southwest corner of the park.
