Boise National Forest · Idaho
Trailhead Jennie Lake Trailhead Drive there
The Jennie Lake Trailhead includes a hitching rack and information kiosk.
A second trailhead for Jennie Lake is on FS Road 348 on Crooked River, 1.5 miles before the Forest Service (FS) Road 372 trailhead.
The Crooked River Trailhead is intended to handle vehicles with horse trailers, as FS Road 372 trailhead has limited parking and turn around for larger vehicles.
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.
