Backpacking camp
San Gorgonio Wilderness, California
Trail Flat Camp is an official itinerary area, permit zone, or source-backed named overnight reference represented by a reachable point on the pinned agency trail network in San Gorgonio Wilderness.
The marker is a route-access reference, not a tent pad. Move off the trail only where travel is permitted, remain inside the authorized zone, and choose a legal durable site under every current setback and closure.
Water planning
South Fork Santa Ana River and Dry Lake are 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.
South Fork Santa Ana River is classified as intermittent and may be dry. Dry Lake is a mapped waterbody; USGS does not classify it here as seasonal or year-round. Confirm current level, access, and quality.
Fire planning
Wood and charcoal fires are prohibited at San Gorgonio Wilderness camps, including existing unofficial rings.
Portable gas stove allowed with permit. Use a portable gas stove only; wood-burning and twig stoves are not allowed.
Carry a valid California Campfire Permit for portable stove use in this remote National Forest area.
Check San Bernardino National Forest alerts before departure; emergency restrictions can suspend stove use.
Seasonal access
No recurring date-based closure of Trail Flat Camp is published. The source-connected approach conditions below and temporary emergency orders still control access.
Source-connected approaches: Vivian Creek Trailhead, South Fork Trailhead, Forsee Creek Trailhead, and 2 more. The wilderness has no universal annual closure, but winter snow and ice, post-fire hazards, storm damage, and emergency forest orders can close individual trails or access roads.
Check San Bernardino National Forest alerts and the exact trail page immediately before departure; carry winter equipment when conditions require it.
