Mendocino National Forest · California
Trailhead Lantz Ridge Trailhead 3,727 ft Drive there
Starting from an old logging deck with great parking, the trail drops down a northern exposure, through dark Douglas Fir old growth forest to mature stands of oak and grass. The creek is surrounded with buckeye, and the wildflowers in spring are terrific.
* Follow M4 to Lantz Ridge, turn right at the green gate, and follow the main road to the landing.
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.
