Fourth Of July Trailhead the Forest Service's write-up
No Fee. · reservation required
Home to yet another one of our glorious wooden suspension pack bridges, at the junction of FS Road 250 and the Fourth of July packbridge, the Fourth of July Trailhead offers a few dispersed campsites and many breathtaking views. Visitors traveling the Windy Ridge Trail will experience beautiful scenery and views into the 1910 Great Burn areas and the Lolo Motorway. The Idaho Centennial Trail also shares a portion of the trail between trails 531 and 634.
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.
