Cougar Rock Campground is located on the south side of the park, on the road between Longmire and Paradise. It is in a steep valley with the Nisqually River across the main road. Thick forest extends through the whole campground providing privacy for campsites. Access to the Wonderland trail is across the road with waterfalls a moderate hike away. Less than 15 minutes of driving can take you to the trails and facilities at Longmire or Paradise.
Cougar Rock is only open for camping during the summer season which runs from late May to early October. Opening and closing dates vary depending on the highly variable mountain weather and snow conditions. The number of sites available in the early season can also be affected by this. During the summer season, campground is open 24 hours a day with a noon checkout time.
This campground is in a mountain river valley, about 3,180 feet above sea level. During the summer, it typically has comfortable day time temperatures, but expect those to fall quickly near sunset. Mountain weather can change rapidly. Most summer days are dry, but rain, thunderstorms and even snow have occurred in July and August. This area is subject to sudden and severe geological hazards such as flooding, landslides and rock fall.
