Keyhole State Park

A wide, beautiful lake, greenery, and plenty of outdoor thrills await visitors to Keyhole State Park. Located in Moorcroft, Wyoming, Keyhole State Park is a public recreation area surrounding Keyhole Reservoir. At the western side of Black Hills, the state park offers ten campgrounds to choose from and numerous other outdoor activities. Keyhole State Park is also only a couple of hours from Mount Rushmore and is convenient to several other nearby areas.

Dogs are permitted in campgrounds, but must be kept on a leash. Pets are restricted from some of the beaches, where posted. Be aware of areas where pets are allowed, but always be mindful of other visitors, keep your pet on a leash of no longer than six feet, and always come prepared to pick up after yourself and your pet. Also be respectful of quiet times in campgrounds, generally from 10 PM until 6 AM and keep your dog from barking excessively.

Open year-round, Keyhole State Park offers a variety of features and activities for outdoor enthusiasts. Swimming, boating, water skiing, fishing, hiking, and even bird-watching are some of the popular activity options visitors can engage in. There is also a privately owned marina and cabins available for rental. There are also group shelters that can be reserved for group events, including weddings, and other family or company events.
