Keystone trip planner

Fewer than 400 people call Keystone home year-round, but the population explodes in summer when crowds flock to nearby Mount Rushmore. Originally established as a mining town in 1883, the town now serves as a vacation spot for visitors to the Black Hills. The town presents itself as a relic of the Old West, although its log buildings have more recent origins. Some remnants of the town's frontier heritage still exist, such as a gold mine and a locomotive, and you'll find modern diversions, including miniature golf courses and museums, mixed in. Above all, though, Keystone serves as a base for seeing the area's monuments, hills-meet-prairie landscape, and wildlife. Keystone is in South Dakota (SD).
