Our emails link to the campground's site grid on ReserveCalifornia; pick the night there (its pages don't take a date from a link).

California State Parks cancellation policy for campsites

How far ahead: up to six months before arrival, on a rolling window. When your date goes on sale →

The reservation start is 12:00 PM on your arrival date, not check-in time: arriving Friday, cancel by noon the Friday before to get your site fees back.

From California State Parks' reservations page and its booking-window page, read Oct 4, 2026. Cabins, yurts and group sites often have their own rules; this is the one for campsites.
