In the agency’s own words

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.

Toilet distances are OpenStreetMap’s, measured for 26 of the 26 sites listed. A site with no reading is unknown, never far.

The price is derived by CAMPANAC, not published per site: the per-night rate this campground publishes for each site’s own site type. 26 of the 26 sites listed carry one, and a site whose type has no published rate sits out of the price rather than being called free.

Measured shade is NLCD Tree Canopy Cover 2024 (USDA Forest Service / MRLC) read at the site’s own coordinate, 27% canopy or more, and only for the sites the agency gave no Shade value. It never changes the agency’s own shaded count beside it.

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: the number below is the only way to be sure.
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.
Nearest place of any size: Foresta, CA, 10.2 mi NW (a census designated place). Straight line.
