Why campsites open up at George J. Hatfield State Recreation Area
California's refund rules create a predictable wave of cancellations. Because campers lose money if they cancel late, most drop their reservations right before the refund deadline — which means openings cluster about a week out from any given date.
| If they cancel… | They get back |
|---|---|
| 7+ days before arrival | Full site fees refunded, minus the cancellation fee |
| 2–6 days before | First night's fee forfeited; the rest refunded, minus the fee |
| Under 2 days / no-show | No refund — all fees forfeited |
