Harney Area Trailheads

Harney Range Trails

Hiking

Within Custer State Park, there are two trailheads to mark the beginning of trails leading to Harney Peak and into the Harney Range Trail System.

Although these trails begin in Custer State Park, they enter the Black Hills National Forest and Black Elk Wilderness on their way to the summit. Trail maps can be obtained at the Peter Norbeck Visitor Center or from the U.S. Forest Service. While most people travel these trails to get to Harney Peak, the entire system offers many more hiking opportunities for those seeking solitude.
