Bridger-Teton National Forest · Wyoming
Trailhead Sweetwater Trailhead Drive there
Sweetwater Trailhead is located approximately 70 miles from Pinedale and it the southernmost of Bridger Wilderness trailheads. This trailhead receives low use, is more primitive and has no facilities. It offers access to the Sweetwater Gap Trail and the Little Sandy Trail. Access is first by paved road then gravel.
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.
