Visitors enjoy the area for its abundant trails, alpine lakes and scenic beauty. Recreation The Twin Lakes Campground area is located just outside the campground and across the road. It offers picnic areas, horse corrals and access to a variety of trails. Lake Cleveland is a two-mile drive from the campground, offering fishing, canoeing and trail opportunities. Several additional hiking, mountain biking, horse and off-road vehicle trails are on the mountain. Facilities The campground contains three group sites, which can accommodate from 40 to 64 people, respectively. All sites are equipped with large picnic tables and campfire rings with grills.

Accessible vault toilets are provided. A campground host is located on-site. Roads and parking spurs within the campground are gravel.
