Stack Rock Trailhead the Forest Service's write-up
The Stack Rock trail is an awesome intermediate-level day hike with lots of shade. Beginning from the trailhead about 13 miles up Bogus Basin Road (look for a gravel pull-out on your left), the Stack Rock trail winds through the beautiful pine trees. The trail leads to Stack Rock, an imposing granite tower with amazing 360 degree views of the Treasure Valley, Horseshoe Bend, and beyond.
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.
