Nothing to book, just show up

One of 1,623 federal campgrounds where the site still goes to whoever pulls in first, and a night costs $14 with nothing added. Get there before noon on a summer weekend.

recreation.gov publishes no availability for a campground you can’t reserve, so there’s no thirty-night reading to draw here. The season bar above is what the agency does publish.

Derived by CAMPANAC: the lowest per-night amount the agency’s fee record states ($14), and no booking fee, because this campground takes no reservations. A weekend here means Friday and Saturday night. Optional charges (an extra vehicle, a second tent, a dump-station fee) are listed separately and aren’t in this total.

How we know

every fact on this page, and where it came from
Right now: National Park Service publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate: the number below is the only way to be sure.
Cell signal: the Park Service’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
