Escape for a Weekend to Keyhole State Park

Between Sundance and Moorcroft at the western rim of the coveted Black Hills sits Keyhole State Park, a family-friendly destination boasting numerous amenity options and activities. Weather permitting, tourists and locals are invited to enjoy the grounds year-round, with vacationers enjoying all the area has to offer from May through September, when pleasant weather abounds and restrooms and drinking water systems are fully operational.

Around the Area

Campbell County Rockpile Museum
Visitors to the museum enjoy collections of rifles, saddles, Native American artifacts, fossils, quilts and other memorabilia. Along with a popular “dress-up” area for kids, there are many hands-on activities for children to engage in while touring the museum. Free admission! Donations appreciated.

Devils Tower National Monument
America’s first national monument hosts a full schedule of activities between mid-June and late August. Junior ranger programs, ranger tower walks and evening entertainment at the amphitheater make the easy 20-minute drive to the tower well worth your time and travel.

Vore Buffalo Jump
The Vore Buffalo Jump is immediately adjacent to Interstate Highway 90 in northeastern Wyoming. The Vore site is a natural sinkhole that was used as a bison trap from about 1500 to 1800 A.D when buffalo were driven over the edge of the sink hole as a method for the Native American tribes to capture the large quantities of meat and hides needed to survive the harsh prairie winters. The site is open from June 1 through Labor Day. Entrance fee is $5 with a $10 maximum per family.
