Big Pine Trailhead (Centennial #89) the Forest Service's write-up

Big Pine Trailhead is located about 3 miles west of Mount Rushmore National Memorial on the north side of HWY-244 and about ¼ mile northwest of Horsethief Lake. Big Pine is part of the 111-mile Centennial Trail which marks the 100th anniversary of South Dakota statehood (1889-1989). Users on this section of the Centennial Trail are treated to beautiful scenery and relative seclusion. While this segment begins on the Black Hills National Forest, the Centennial Trail crosses multiple jurisdictions and was developed through combined efforts of the Forest Service, Bureau of Land Management, National Park Service, and South Dakota Department of Game, Fish and Parks for public enjoyment.

This trailhead has a large parking area to accommodate horse trailers, along with a bulletin board on site with information and maps available to the public.

About this trail's facts

The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the forest's own site before you go.
