Coal Ridge Trailhead the Forest Service's write-up
Coal Ridge Trailhead is located approximately 35 miles southwest of Custer, SD and it provides access to the Coal Ridge trail system, which is comprised of 2.5 miles of scenic loop trail open to vehicles 62” or less in width. A trail permit is required to use these trails. A bulletin board is on site with information and maps available to the public.
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.
