Keystone
Keystone travel guide
The closest town to Mount Rushmore, in the heart of the Black Hills.
Keystone is the nearest town to Mount Rushmore, with Custer State Park, the Crazy Horse Memorial and scenic drives like Iron Mountain Road close by. Visit from late May to September and allow 2 to 3 days. Rapid City airport is about 45 minutes away by road.
Keystone is a small former gold-mining town in the Black Hills of western South Dakota, about 3 km from Mount Rushmore National Memorial. Founded in the 1880s, it now lives mainly from tourism, with a main street of motels, restaurants and shops that fills with visitors in summer.
The town is a convenient base for the Black Hills: Iron Mountain Road and Custer State Park lie to the south, the Crazy Horse Memorial is a short drive away, and the 1880 Train runs from Keystone to Hill City. Most businesses open from about May to September, which is also the best time to visit.

Mount Rushmore, Custer State Park and Crazy Horse in two days
Keystone sits at the centre of the Black Hills' main sights, so two or three days are enough to see the highlights without long drives. A car is essential, and summer mornings are the quietest time at the big sites.
- Day one: visit Mount Rushmore in the morning and walk the Presidential Trail below the carving. Return for the evening lighting ceremony, held in summer.
- Day two: drive Iron Mountain Road south, with its pigtail bridges and tunnels, into Custer State Park. Follow the Wildlife Loop Road for bison and pronghorn, then return via Needles Highway and Sylvan Lake.
- Day three: see the Crazy Horse Memorial and its museum, ride the 1880 Train from Keystone to Hill City, or go underground at Wind Cave or Jewel Cave.
With another day, Badlands National Park is about 1.5 hours east.
