About Horsethief Lake Campground
Overview
Located 10 miles south of Hill City, South Dakota, Horsethief Lake Campground is a delightful setting for visitors seeking recreation and relaxation in Black Hills National Forest. This campground is 2 miles from Mount Rushmore National Memorial and adjacent to Horsethief Lake. Sites are tucked into a forest of towering ponderosa and lodgepole pine.
Recreation
Black Hills National Forest offers visitors a multitude of recreational opportunites throughout all seasons. Hiking, fishing, horseback riding, mountain biking, and riding off-highway vehicles are popular in summer and early autumn. Winter landscapes are ideal for snowshoeing, skiing and snowmobiling. Hundreds of miles of trails and roads offer a variety of terrain for mountain bikers. Hikers and bikers can access the nearby George S. Mickelson Trail, which traverses over 100 miles through the heart of the Black Hills. The majority of the trail follows an abandoned railroad branch line and includes 4 tunnels, over 100 converted railroad bridges, and 15 established trailheads. The trail surface is packed gravel, traversing mountain, meadow, and forest terrain. The trail is named in honor of the former South Dakota governor who crusaded for the trail. For those seeking higher elevations, a day-long trek to the summit of nearby Black Elk Peak is worth the effort. Black Elk Peak is the highest natural point in the United States east of the Rocky Mountains. Most of the summit is bare granite and offers expansive views of the surrounding area. An old stone tower at the top(Harney Lookout Tower), once used as a fire lookout, is still open to hikers.

Natural Features
Located in western South Dakota and northeastern Wyoming, Black Hills National Forest encompasses nearly 1.25 million acres of rugged rock formations, canyons and gulches, open grassland parks, tumbling streams, deep blue lakes, and unique caves.
Derived from the Lakota language, the words "Paha Sapa," meaning "hills that are black," honor the dark, pine-covered hills rising several thousand feet above the surrounding prairie.
Wildlife in the area abounds. Bighorn sheep navigate mountainous terrain, while elk, deer and pronghorn gather in forests and prairies. Bald eagles, hawks, osprey, peregrine falcon, and hundreds of other bird species can be found in the forest, especially along streams, lakes and rivers.
