Thomes Gorge Trailhead the Forest Service's write-up

season January to

This trail starts from the Thomes Gorge trail head on Forest Road M4 and is named for the people indigenous to this locale. The trail begins in arid chaparral, with extensive views of the foothill country. Passing through gray pine and meandering around seasonal vernal pools, the trail drops into the spectacular geologic formations of Thomes Gorge, ending near the deep, sparkling pools of Thomes Creek. In summer it's a hot midday hike with little water along the way. Be sure to pack plenty to drink. The trail can also be accessed via the Mud Flat Road, Forest Road 23N35.

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.
