A reservation or permit is still required, and the map does not guarantee site availability or current access.
Water planning
The Forest Service says water is available along Potrero John Trail most of the year, including at the creekside camp, but it is not potable and flow can diminish in dry periods.
Filter, boil, or otherwise disinfect all creek water before drinking.
This is a natural, seasonally variable creek. Carry a backup supply and verify recent flow during drought or late summer.
Fire planning
Potrero John Camp is a named Los Padres backcountry camp. Use only an existing legal ring when the current forest order allows wood fires; never build a ring in a drainage or outside the established camp.
Shutoff-valve stove with California permit. Use a gas, LPG, jellied-petroleum, or pressurized-liquid-fuel stove with a working shutoff valve. Wood and twig stoves follow the campfire restriction.
Carry a valid California Campfire Permit for an allowed stove or campfire.
Check the Potrero John page and Los Padres alerts before departure; wildfire danger can prohibit fires or all flame devices regardless of an existing ring.
Seasonal access
No recurring date-based closure of Potrero John Camp is published. The source-connected approach conditions below and temporary emergency orders still control access.
Source-connected approach: Potrero John Trailhead. 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.
