Potrero John Trail (23W06) WILDERNESS
Length: 1.6 miles
Difficulty: easy
Take Highway 33 north of Ojai to the trailhead at mile marker 32.10. The trail is on the right hand side of the highway. This trail provides a beautiful day hike following a stream channel into the Sespe Wilderness. It has running water most of the year. The trail ends at Potrero John Camp, but it can be fun to explore the drainage beyond the camp.
Restrictions <a href="https://www.readyforwildfire.org/permits/campfire-permit/">Campfire permits</a> are required. Check for <a href="http://www.fs.usda.gov/detail/lpnf/?cid=STELPRDB5401877">current fire restrictions</a>.

Every trail in Los Padres National Forest
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.
