Backpacking camp
Marble Mountain Wilderness, California
Campbell Lake 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 Marble Mountain 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
Campbell Lake and Unnamed mapped stream or river are mapped at or near 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.
Campbell Lake is a mapped waterbody; USGS does not classify it here as seasonal or year-round. Confirm current level, access, and quality. Unnamed mapped stream or river is classified as perennial in USGS hydrography, but current flow still must be confirmed.
Fire planning
Campbell Lake is an undeveloped backcountry camp area in Marble Mountain Wilderness. The Forest Service Marble Mountain guide requires a campfire permit for campers. Check current fire orders because wood fires or all flame can be prohibited even with a permit. Never treat an old ring as proof that a fire is legal, and do not build a new ring where fires are prohibited.
Shutoff-valve gas or pressurized-fuel stove with permit. Use a gas, LPG, jellied-petroleum, or pressurized-liquid-fuel stove with a working shutoff valve. Twig and wood-burning stoves follow the campfire rule and are prohibited anywhere wood fires are prohibited.
Carry a valid California Campfire Permit for a portable stove or any otherwise-legal fire; the permit never overrides a forest closure, fire-danger order, elevation limit, or named-area prohibition.
Check USDA Forest Service's current alerts and the selected trailhead posting before departure. The standing rule shown here remains subordinate to a newer emergency order.
Seasonal access
No recurring date-based closure of Campbell Lake is published. The source-connected approach conditions below and temporary emergency orders still control access.
Source-connected approaches: Boulder Creek Trailhead, Box Camp Trailhead, Haypress Trailhead, and 8 more. Marble Mountain Wilderness has no published recurring closure season, but high routes and remote access roads are commonly snowbound into late spring or early summer and can close after wildfire or storm damage.
Check Klamath National Forest alerts and confirm the exact forest-road approach, gate, and vehicle requirements before departure.
