RV Rentals in Keyhole State Park



Keyhole State Park is located off I-90 on a scenic location between the towns of Sundance and Moorcroft, on the western end of the Black Hills around Keyhole Reservoir. If you are visiting during the winter, seasonal road closures due to black ice and rock falls may force you to find alternative routes. The authorities may restrict driving RVs on the roads during winters.

The park is massive mainly because the Keyhole Resorvor is massive, encompassing 13,700 acres. You're going to have to drive greater distances to get from one side of the park to the other. The roads are generally wide, but a few roads are a little narrow for big rigs. Dust is also problematic on the roads. There is sufficient parking in the park at campgrounds, park entrance, and visitors centers. Overflow parking is facilitated, and towed parking is also available.
