No reading yet, book on recreation.gov

Every site here is reservable, and the record lists none held back for anyone who drives up.

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 priceNational Park Service
The National Park 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.
Rock Quarry Group Campsite Fee Up to 15 People$35
Rock Quarry Group Campsite Fee 15-35 People$75
The booking feerecreation.gov
Reservation fee, booked online$8
One fee per reservation, however many nights you book, and it’s non-refundable. $9 if you book by phone, $3 in person.
Pass discounts only apply to the recreation (or use) fee for the facility. Other charges such as electricity or water hookups, reservation or other fees are not eligible for a discount.
What a stay costs
The agency publishes no nightly rate for this campground, so there’s nothing to add the $8 booking fee to. We won’t total a receipt with a number missing from it.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

Rock Quarry Group Campsite is in Texas’s 23rd congressional district. Whoever holds it votes on the laws that decide what happens to this land. See how its representative votes on public lands →

Our roster still carries Tony Gonzales for this district and the current federal record doesn’t list them as sitting, so we’re not naming a representative here until the two agree.
