The Willamette National Forest stretches for 110 miles with varied landscapes of high mountains, narrow canyons, cascading streams, and wooded slopes. Native wildlife includes Roosevelt elk, black bear, bald eagles, black tail deer and bobcats. Cougar Reservoir sits at 1,700 feet in elevation and is an estimated 1,280 acres. Some campsites have views of Cougar Reservoir and all sites are an easy walk to the swimming area.
Recreation: Activities on the reservoir include water skiing, swimming, fishing and canoeing. Anglers might catch some quality rainbow trout. The campground is close to a large network of hiking trails in the Olallie Trail Area. Half of the trails are open to biking as well.
