Provider Coverage

ReserveCalifornia campsite cancellation alerts

Yes. OpenCampsite watches supported ReserveCalifornia campgrounds and sends a notice when a check finds a match. ReserveCalifornia also offers Create Notification emails. Choose your dates and campsite type, then book on the official site when an opening appears. Neither notice holds a site.

Alerts are available for 325 locations here — we watch for cancellations and new openings around the clock.

How ReserveCalifornia availability alerts work

  • California State Parks uses a six-month rolling reservation window, with new inventory opening daily at 8 a.m. Pacific.
  • Under the current statewide policy, most cancelled sites become bookable at 8 a.m. on the day after the cancellation. Openings remain first-come, first-served.

    ReserveCalifornia campsite alert questions

    Does ReserveCalifornia have campsite availability notifications?

    Yes. ReserveCalifornia's Create Notification workflow lets campers choose dates, facilities, and unit type, and says it will email them if a site becomes available.

    When do cancelled ReserveCalifornia campsites become available?

    California State Parks says most cancelled sites become available in the reservation system at 8 a.m. on the day after the cancellation. A notification is not a hold, so another camper can still book the opening first.

    Does OpenCampsite book a ReserveCalifornia campsite for me?

    No. OpenCampsite monitors supported campgrounds and notifies you when a check finds a matching opening. You complete the reservation yourself on ReserveCalifornia while the site is still available.
