Bridger-Teton National Forest · Wyoming
Trailhead Trail Creek Trailhead - Greys River Drive there
A short north-side spur just a mile above the Greys/ Little Greys junction offers parking at a dispersed site before becoming a two-track; or if you have a horse trailer, park just on the north side of the road before the spur and start your trail day there. The Elk Mountain Lookout Spur travels east along the ridgetop.
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.
