The Basics

To experience the whimsical, disorienting, and downright strange Cosmos Mystery Area without first waiting in line, it's best to prebook tickets. To find your way through the crooked cabin (aka the Mystery House), plan to join for a 40-minute guided tour—included with admission—and take advantage of the live demonstrations and optical illusions. To round out your Black Hills itinerary, pair your visit with a stop at Custer State Park and the iconic Mount Rushmore.

Visiting Mt. Rushmore National Memorial

One of the best features of Cosmos Mystery Area is its proximity to South Dakota's must-see attraction: Mt. Rushmore. At this historic landmark, you find the faces of four presidents carved into the granite hillside. Tours to Mt. Rushmore National Memorial often depart from nearby Rapid City and typically include a ride along Custer State Park Scenic Drive, so you can see more without the hassles of driving yourself.
