Nothing to book, just show up

One of 1,623 federal campgrounds where the site still goes to whoever pulls in first, and it costs nothing at all. 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.

What a stay costs
A night, and a whole weekendDerivedNothing

Derived by CAMPANAC: the agency’s own record says there’s no camping fee, 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.
