Trailhead
Sespe Wilderness, Los Padres National Forest, California
Potrero John Trailhead is a source-backed overnight access point in Interior Los Padres Wildernesses. Kampilo publishes only the official trail geometry and permit or camp authorization options represented in the mapped catalog.
The mapped line is a planning reference rather than a guarantee of current access. Confirm road, parking, trail, weather, fire, permit, and closure conditions with the land manager before departure.
Seasonal access
No recurring date-based closure of Potrero John Trailhead is published. Highway 33 at mile marker 32.10 and temporary emergency orders still control access.
Highway 33 at mile marker 32.10: Use the Potrero John Trail 23W06 turnout on State Route 33 at mile marker 32.10, about 8 miles north of the Rose Valley Road junction. Parking is free but there is no potable water; check Highway 33, creek flow, heat, storm damage, fire restrictions, and current forest orders. Nira and the Upper Manzana Creek Trail do not have a published recurring closure window. Wet-weather road closures, winter creek crossings, wildfire orders, summer heat, and storm damage can still remove safe access; Manzana Creek camps are most dependable in spring and early summer.
Check the Nira site page and Los Padres alerts, then confirm the road, Upper Manzana Creek Trail, crossings, fire restrictions, and creek flow immediately before departure.
