Eastside Campground is located on the shores of scenic Sagehen Reservoir at an elevation of 4,956 feet. Visitors enjoy boating, fishing and exploring the non-motorized Sagehen Reservoir Trail.

Recreation

Sagehen Reservoir offers great boating, canoeing, and rainbow trout fishing. Boat ramps and docks are located nearby at both Antelope and Sagehen Creek Campgrounds. There is a 15 mph speed limit on the reservoir. Hiking, biking, horse, and ATV trails are abundant in the area. The non-motorized Sagehen Reservoir Trail, a 4-mile loop around the lake, offers great fishing spots, beautiful viewpoints, and wildlife watching opportunities for hikers, mountain bikers and horseback riders. The Sagehen and KYAOTT ATV Trail Systems can be accessed near the reservoir, offering more than 35 miles of trails for ATVs and motorcycles, but hikers, mountain bikers and horseback riders can enjoy these trails as well.

Facilities

The campground is made up of several single sites or serves as one reservable, accessible group site that can accommodate up to 50 people and 10 vehicles. Most of the campsites afford partial lake views. Picnic tables, campfire rings, a vault toilet, and hand-pumped drinking water are provided. A campground host is located at nearby Antelope Campground, where firewood can be purchased.

Natural Features

The campground is situated in a forest of towering Ponderosa pine, Engelmann spruce, Douglas fir, and grand fir. Most sites have plentiful shade. Summer temperatures range from 80 to 90-degree days to cooler nights. A variety of berries and mushrooms can be found throughout the area. Local wildlife includes deer, elk, black bear, goshawk, woodpeckers, and boreal owls.
