Overview
The Spirit Mound State Historic Prairie is a rare and culturally significant landscape that preserves a site visited by the Lewis and Clark Expedition in 1804. Rising above the surrounding plains, the mound was once believed by Indigenous tribes to be inhabited by "little people" with supernatural powers. Today, the site is a restored tallgrass prairie, offering a 1.5-mile round-trip trail that leads to the summit, where visitors can enjoy sweeping views of the Missouri River Valley and imagine the historic journey of the Corps of Discovery.
Managed by South Dakota Game, Fish and Parks, the area is a haven for native grasses, wildflowers, and prairie wildlife. Interpretive signs along the trail provide insight into the mound’s natural and historical significance. With no admission fee and a peaceful, open setting, Spirit Mound offers a contemplative experience that connects visitors to both the ecological richness and the storied past of the Northern Plains.
