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. Keyhole State Park has 10 campgrounds, all of which are reservation only.
Parkwide Asphalt Rehabilitation Project to Begin at Keyhole State Park
MOORCROFT, Wyo. – Oct. 30, 2026 – A parkwide asphalt rehabilitation project will begin at Keyhole State Park on Nov. 2, 2026. This project encompasses asphalt repairs on Marina Road, Pat’s Point Road, and sections of Brandenburg Loop. Work will continue through the end of 2026, with additional work expected in June 2027 when temperatures allow.
Keyhole State Park staff ask visitors to use caution when entering the park through either the Marina Road or Coulter Bay entrances and to follow any temporary traffic direction changes.
Electric sites at the Coulter Bay campground will remain closed until Dec. 1, 2026, to accommodate heavy equipment, trucks, and construction materials.
