About Our Site - Keyhole State Park


Keyhole State Park offers swimming, hiking, boating, water skiing, bird-watching and fishing. Some of the state’s largest fish have been caught at Keyhole. You can also reserve one of our 3 group shelters to host weddings, family get togethers, and company picnics. Keyhole State Park is located on the western edge of the Black Hills, between Sundance and Moorcroft, and is easily accessed off I-90 at exit 165. Travel north 6 miles and the entrance to Park Headquarters will be on your left. Once here, you can select your campsite from one of our ten campgrounds. The Tatanka campground was made to order for those of you who want to reserve your site in advance.
