Grace Coolidge Campground is a small, well-maintained campground in Custer State Park with approximately 27 sites situated along Grace Coolidge Creek, offering excellent access for trout fishing directly adjacent to campsites.

The campground features clean facilities including flush toilets and hot showers, potable water, picnic tables, and both tent-only (north side) and RV-friendly sites (south side) with electric hookups available.

Located a half-mile west of the Custer State Park office on US Highway 16A, it serves as a convenient base for accessing nearby hiking trails and the park's Wildlife Loop while enjoying a quiet, shaded camping experience.
