San Onofre State Beach: reservations and availability alerts
Reservations for San Onofre State Beach in California are made through ReserveCalifornia.
This guide lists the locations we track, where to find reservation rules, and nearby alternatives.
What we track at San Onofre State Beach
All 14 can be watched for openings. The catalog records campground and group campground here.
How booking works on ReserveCalifornia
California State Parks sites release on a rolling window six months ahead of arrival, with a new day of inventory opening at 8 am Pacific every morning.
ReserveCalifornia has a native “Create Notification” workflow that emails you if a selected site becomes available. The notice does not hold the site, so you still need to book it before another camper does.
Reservation-system facts checked against official sources on September 9, 2026. Policies change — the reservation system's own pages are always authoritative.
Timing and seasons
We don't publish operating dates for individual locations at San Onofre State Beach. Check the location's official page on ReserveCalifornia for the dates available for your visit.

Cancellations and returned openings
For arrivals on or after July 1, 2026, a new statewide policy applies: cancel seven or more days out for a full site-fee refund minus the $8.25 cancellation fee; two to six days out forfeits the first night; inside 48 hours (or a no-show) forfeits everything.
California State Parks says most cancelled sites become bookable at 8 am the following morning. This is separate from the six-month release of new arrival dates, and does not mean every campground receives new availability each day.
The playbook
- Check the official reservation page for your dates and requirements before creating an alert.
- If your dates are sold out, choose the locations and dates you would book. We check ReserveCalifornia on an adaptive schedule.
- Choose email or text for each alert. Enable browser notifications separately for all your alerts.
- Consider nearby alternatives. San Clemente State Beach is about 3 miles away and has 4 locations we can watch. These are straight-line distances, not driving distances.
- When an alert arrives, check availability and book on ReserveCalifornia. OpenCampsite doesn't take bookings or hold a reservation, and someone else may book the opening first.
