About Roughlock Falls

Roughlock Falls is a picturesque cascade tucked into Spearfish Canyon in the northern Black Hills. The waterfall and its immediate surroundings lie within the Black Hills National Forest and are managed by the U.S. Forest Service, making the area a well-loved stop for photographers, day hikers, and anyone wanting a quick dose of canyon scenery. Framed by the steep walls of Spearfish Canyon, the falls offer an inviting blend of rushing water and wooded outlooks that reward a short outing. Getting to the falls involves a moderate out-and-back walk that delivers big scenery in a compact package. The route uses a combination of native-surface tread and a USFS-designated spur—Rimrock Spur B (Trail #79B)—which provides a slightly steeper approach. At about 2.4 miles round-trip with roughly 350 feet of elevation gain, the hike is approachable for most hikers who are comfortable on natural single-track and modest grades.

The Setting

Roughlock Falls sits at 5,131 feet within Black Hills National Forest, fed by the Little Spearfish Creek, in the high mountains of South Dakota.

Spearfish Falls, the tallest waterfall in South Dakota at 47 feet, lies 0.7 miles to the east.
