There are more than 170 campsites spread between nine different campgrounds at Keyhole State Park. Many of the campsites have picnic tables and charcoal grills, and most will accommodate RVs or trailers.

This state park is located at Keyhole Reservoir in northeast Wyoming. The reservoir is popular with residents for fishing, but the park is located between the Black Hills and Bighorn Mountains which makes it popular with travelers as well. Devils Tower National Monument is only about 20 miles from the park.

The park and camping areas are clean and well maintained. Vault toilets and trash containers are available in each campground. The park is open throughout the year, but some services may not be available during the winter months.

A private marina at the park sells gasoline, fishing gear, groceries, and propane. Shower rentals are also available at the marina.

Overnight camping fees are currently $10 for Wyoming residents or $17 for non-residents. An annual camping pass is also available for state residents.


Take Interstate 90 to Exit 165, then head north on Pine Ridge Road. Continue to the right when Pine Ridge Road intersects with Highway 180. It is approximately five miles from Exit 165 to Keyhole State Park along paved roads.
