Black Elk Peak

Black Elk Peak is the granite high point of South Dakota, set in the Black Elk Wilderness with a stone fire lookout on its summit. It lies just outside Custer State Park, but the popular way up starts at Sylvan Lake inside the park. You’re hiking for a bare-rock summit, the old lookout and a broad view over the Black Hills that can reach four states. Save this for a day when you want a real climb: the shortest approach is a 6.6-mile round trip, not a quick stop.

Trail 9 starts by the footbridge at Sylvan Lake’s swimming beach and climbs 3.3 miles each way. The park map calls it moderate, but a rocky final stretch and nearly seven miles on foot make it a substantial outing; hikers often find it strenuous. Trail 4 starts at the southeast side of the day-use parking area and reaches the peak in 3.5 miles one way via connecting trails. It’s a longer alternative, and adding Little Devil’s Tower makes for a still bigger day. Trail junctions in the wilderness can be easy to miss on the return, so keep your map handy. Trail 9 gets heavy use in peak season; an early start can mean a quieter summit and easier parking.

The Sylvan Lake trailheads are inside Custer State Park, where an entrance license is required; the routes then cross into federal wilderness. This is a hike-only summit, with no road or short accessible path to the top. The area map warns there are no restrooms along the trails, so plan around the day-use area before setting out. There’s no reliable water on the climb; carry what you’ll need for the full outing. The summit is cooler and windier than the lake, and summer storms can bring hail and strong winds, so take an extra layer.

The lookout is part of a larger summit compound with a stairway, pump house and small dam. From the exposed granite, the view sweeps over the Black Hills and can reach South Dakota, Nebraska, Wyoming and Montana. For a photo that feels like this place, include the stone tower or stairway with some of the pale granite in the frame; a horizon-only shot misses the summit’s scale and character.

A wooden lookout was first put on the summit in 1911. The Civilian Conservation Corps built the present stone tower from 1938 to 1940; a 1935 dam held water for the site, and a pump house followed. The tower was last staffed in 1967. It’s now a historic landmark rather than an operating fire lookout, and the summit structures make the climb more interesting than a view alone.

The peak was renamed in 2016 to honor Nicholas Black Elk, an Oglala Lakota spiritual leader. Older maps may still call it Harney Peak, and the historic structure is still known as Harney Fire Lookout. That distinction helps make sense of the old and new names you’ll see for the same summit.

The pale ledges underfoot are part of a huge granite dome built from hundreds of separate igneous intrusions. Metamorphic rock around the dome dips away from it, so the summit’s bare slabs are a small, walkable glimpse of how the Black Hills were formed.
