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.

Keyhole State Park Partners With Audubon Society for Bird Banding Events


Join the Audubon Society and aid in the banding of birds at Keyhole State Park, June 6, 15, and 27 just below the dam adjacent to the Rocky Point Campground. The operation begins at 6 a.m. and continues until approximately noon, or whenever the temperature rises to a level that may stress the birds. Volunteers are asked to help remove birds from nets, band birds, record information and help release them safely back into the wild. All ages are welcome. Volunteers are encouraged to come prepared for the weather including sunscreen and drinking water. For more information, please call Keyhole State Park at 307-756-3596. Other bird banding events are scheduled for July 4, 18, 25 and August 8.
