The Black Hills cover an area that is 65 miles wide and 125 miles long. Most of the area is in western South Dakota, with a small part in northeastern Wyoming. There are 11 reservoirs, 30 campgrounds, 32 picnic areas, two scenic byways, two scenic overlooks, and 353 miles of trails within the forest. Both the Norbeck Wildlife Preserve and the Black Elk Wilderness are also part of the forest. Hiking, bicycling, fishing and horseback riding are among the many opportunities for outdoor recreation.
