Black Elk Peak is the summit of the Black Elk Wilderness and the highest point in the Black Hills, at roughly 7,200 feet. It is commonly described as the highest point east of the Rockies. The mountain was long known as Harney Peak and was renamed in honor of the Oglala Lakota holy man Black Elk, and the area is sacred to many American Indians. The most popular route is Trail 9 from Sylvan Lake in Custer State Park, a loop of around six and a half miles with an elevation gain of roughly 1,450 feet, according to one trail guide. The hike passes granite formations, forests and views of the Needles, and it ends at a historic stone lookout tower at the top. Allow four to six hours for the round trip, bring plenty of water and check the weather before you go, since afternoon thunderstorms are common in summer. There is no charge for the wilderness itself, but you need the park entrance license to park at Sylvan Lake. Follow the wilderness rules, which cover group size, camping and fires.
The hike's reputation is for good reason. The trail starts at the lake, passes through pine forest and climbs over granite slabs, with views opening up as you gain elevation. A side trail leads to Little Devils Tower, a scenic detour for those with energy. The final approach is a series of stone steps to the tower, and the summit offers sweeping views over the Hills and across the plains.
It is a demanding hike for beginners but accessible to most reasonably fit visitors who take their time. Children who are used to walking can manage it, though shorter legs may need breaks.
Respect matters on this mountain. The area is sacred to the Lakota and other nations, and visitors are asked to stay on the trail, avoid leaving offerings or objects, and treat the summit with care. The name change reflects that significance, and signs along the route explain some of the context. The wilderness has rules that cover camping, fires and group size, and it is subject to heavy use, particularly on Trail 9. Pack out everything you bring, stay on marked paths and keep dogs under control if they are permitted where you are walking.
Plan carefully. Start early, ideally before nine in the morning, to avoid the heat and the summer afternoon storms, and carry more water than you think you need. Wear sturdy shoes, bring layers and a rain jacket, and have a map or a downloaded route, since cell service is unreliable. The trailhead parking at Sylvan Lake fills quickly in summer, and the road to the lake may be closed in winter, which changes access.
Combine the hike with a lakeside lunch or a drive along Needles Highway. Shorter alternatives, such as Cathedral Spires, offer similar scenery with less commitment for visitors who are not ready for a full day on the trail.
