Keyhole Marina

Keyhole Marina is the primary developed access point on Keyhole Reservoir, offering a full-service boat launch with dock facilities for both wet and dry slip storage. Located just 6 miles off I-90 near Moorcroft, the marina provides fuel, groceries, beverages, and boating supplies, making it convenient for day trips or extended outings. The facility features a boat ramp with a dock system designed to assist with launching and retrieval—note that fishing from the dock is prohibited.

Keyhole Reservoir offers 14,720 acres of navigable water suitable for kayaking, canoeing, and motorboating. **Ramps are open seasonally according to lake conditions**, so check current water levels before visiting. All boats must be properly registered and inspected for aquatic invasive species before launching. Ensure your vessel has required safety equipment including life jackets and fire extinguishers. If this ramp is at capacity or closed, additional boat ramps with docks are available at Wind Creek Campground, Coulter Bay Area, and Pat's Point Campground.
