The place

the agency’s own description · what’s there

In the agency’s own words

Coldbrook Campground offers 22 shaded campsites* at the intersection of Coldbrook and Soldier Creeks that are open year round. Available on a first-come, first-serve basis, each campsite can fit up eight people and two vehicles (additional fee applies for the second vehicle). This campground is less populated then nearby Crystal Lake Recreation Area. However, it does reach capacity on most summer weekends. Each campsite has a fire pit and grill, and picnic tables are available on the grounds. Potable water is available on the campgrounds. Keep reading

The trailhead for the 7-mile round trip hike to the summit of Smith Mountain is just 1/3 of a mile away and the popular Bridge to Nowhere hike is a short drive away. RV's are allowed up to 22 feet, but there are no hookups for electricity or waste. *Note: Camping - $12 per night per site, $5 for extra vehicle. Day use - $5 per vehicle. Adventure Pass will be honored for day use. Campsites are first-come-first-served. Adventure Pass required for vehicles parked outside the campground. A California Campfire Permit is required.

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 $12 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 ($12), 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: U.S. Forest 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.
Cell signal: the Forest 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.
