Adams Gulch Trailhead the Forest Service's write-up
Adams Gulch Trailhead is the most popular trailhead on the Ketchum Ranger District. Located just outside of Ketchum, it provides a jumping off point for a quick hike on Sunnyside Trail, a bike ride down Forbiden Fruit, or a backcounty adventure to Fox Peak. Trailhead amenities include vault toilets and an interpretive sign. All trails in Adams Gulch are closed to motor vehicles, including e-bikes, except for Old Adams Gulch Road - Eves Gulch Tr. No. 146. Overnight camping is not permitted in at the trailhead.
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.
