San Juan National Forest · Colorado
Trailhead West Fork Trailhead Drive there
West Fork Trailhead gives access to the West Fork Trail (561) which leads to the Rainbow Hot Springs and into the Weminuche Wilderness. However, the Forest Service urges the public to use extreme caution visiting the area because of significant impacts from the West Fork Fire of 2013 and an ongoing spruce bark beetle epidemic.
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.
