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 16, 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.
Adventure Pass ($5/vehicle/day) or America the Beautiful Pass required.
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.
