Trans-Catalina Trail, California
Black Jack Campground is an official designated overnight location reached by the pinned agency trail route shown in Kampilo.
A reservation or permit is still required, and the map does not guarantee site availability or current access.
Water planning
Unnamed mapped stream or river is mapped within 0.5 mile of the camp-area marker. This is map evidence, not a real-time flow report.
Natural water is not verified potable. Filter and disinfect it or boil it according to the linked land-manager guidance before drinking.
Unnamed mapped stream or river is classified as intermittent and may be dry.
Fire planning
Black Jack Campground is a reserved Trans-Catalina Trail campground. Use wood or charcoal only in a facility explicitly provided for the assigned site and only when the reservation's current fire notice permits it; never build a ground fire or gather island vegetation.
Portable gas stove at the reserved campground. Use a self-contained gas stove at the assigned campsite and follow the campground's current wind and fire-danger restrictions.
The campsite reservation and Conservancy hiking authorization remain required. The manager does not identify a separate California Campfire Permit for an approved campground stove.
Check the exact campground reservation notice immediately before travel. The current notice controls fire facilities, Parsons Landing locker service, and any wind- or fire-danger suspension of flame devices.
Seasonal access
No recurring date-based closure of Black Jack Campground is published. The source-connected approach conditions below and temporary emergency orders still control access.
Source-connected approaches: Avalon Trans-Catalina Trailhead, Two Harbors Trans-Catalina Trailhead. The Trans-Catalina Trail and reserved campgrounds have no single published annual closure season, but ferry service, campground availability, wildfire, extreme heat, storms, and Conservancy closures can interrupt an itinerary.
Confirm ferries, hiking authorization, every campground reservation, trail conditions, fire restrictions, and water service before leaving the mainland.
