This Cabinet Mountains Wilderness trail follows the Middle Fork of the Bull River drainage into the widest and one of the most remote sections of the Cabinet Mountains Wilderness. The trail ends at a dispersed campsite approximately 6 miles from the trailhead. An old, unmaintained trail continues into the Ibex Creek drainage, and approximately 5 miles from the trailhead an old, unmaintained trail leads up to Little Ibex Lake. There are a couple small, dispersed campsites around the lake. Little Ibex Lake is very shallow and does not hold a population of fish.

There are two major stream crossings at about the one mile mark. These crossings can be challenging and dangerous during peak flows.

About this trail's facts

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.
