Phone before you drive

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.

Booking window6 months outBooking opens 6 months ahead; today unlocks arrivals through April 17, 2027. The agency publishes no reservable season in the record we hold, so the window may close earlier than that.recreation.gov

What you actually pay

The sign priceU.S. Forest Service
The U.S. Forest Service publishes no per-night rate for this campground that we can read, so there’s no sign price to print. That’s a gap in the record, not a free campground.
Check the campground table for fee information.
The booking feerecreation.gov
We hold no recreation.gov booking record for this campground, so we can’t say whether a booking fee applies.
What a stay costs
The agency publishes no nightly rate for this campground, so there’s no total to show.

How we know

every fact on this page, and where it came from
Right now: U.S. Forest Service’s own recreation database flags it not open and publishes no reason and no date. That’s a flag, not a notice.
Fall color: More Than Just Parks foliage tracker, joined to this campground by distance (23 km) · Oct 10, 2026
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.
