ReserveCalifornia availability rules

- Rules checked
ReserveCalifornia is the reservation system for California State Parks. Its availability follows two fixed daily events, both at 8 a.m. Pacific: the release of a new arrival date, and the return of most sites cancelled the day before.
Quick reference
| Topic | Rule |
|---|---|
| Booking window | Six months before the arrival date |
| Release time | 8 a.m. Pacific, daily |
| Month-end dates | August 29-31 arrivals open March 1 |
| Cancelled sites | Most become bookable at 8 a.m. the day after cancellation |
| Full site-fee refund | Cancel 7 or more days before the start date |
| Late arrival | Site held until noon the day after the start date |
| Walk-up sites | Some sites remain first-come, first-served |
| Drawings | Up to eight months in advance for certain parks |
The six-month rolling window
California State Parks lets campsites and lodging be reserved six months in advance of the current date. A new arrival date opens each morning at 8 a.m. An arrival on June 20 opens on December 20.
The window is counted in calendar months and adjusts for month length. The agency's own example: a booking made on February 28 can start as late as August 28, and on March 1 the arrival dates August 29, 30 and 31 all open.
How many nights can be booked from a newly opened arrival date depends on the park's maximum-stay rule. California State Parks does not give a single statewide number on its window page.
The 8 a.m. cancellation return
Most systems put a cancelled site back on sale without a published schedule. California State Parks states one: most cancelled sites become available for booking at 8 a.m. on the day following the cancellation.
Three consequences follow from that sentence.
- A site cancelled today is in an in-between state until tomorrow morning. It is neither reserved nor bookable.
- Returned sites and newly released dates appear at the same minute each day.
- The word "most" is the agency's. Some cancelled sites can reappear at other times, and the agency does not list which.
Cancellation tiers
These apply to reservations that start on or after July 1, 2026. Reservations starting earlier fall under the previous policy.
| When the reservation is cancelled | Outcome |
|---|---|
| 7 or more days before the start date | Site fees refunded |
| 2 to 6 days before the start date | First night's site fee kept as a penalty |
| Within 48 hours of arrival | All fees paid are forfeited |
| No-show | All fees paid are forfeited |
The $8.25 reservation fee and any modification fee are not refundable. The FAQ also describes an $8.25 cancellation fee deducted from refunds; it does not state clearly whether that applies in the seven-day tier, so confirm on ReserveCalifornia before cancelling.
California State Parks gives a worked deadline for the first tier: for a reservation starting on a Friday, cancel by noon the previous Friday.
No-shows
A reservation that is neither used nor cancelled is a no-show. Three no-shows in one calendar year lead to a one-year ban on making reservations. The agency says ReserveCalifornia will notify an account holder before any restriction is applied.
A reserved site is held for a late arrival until noon on the day after the start date. After that the holder can be marked a no-show and the site released. A camper who will arrive later than that is told to call the park number on the confirmation email.
Sites the calendar does not show
- First-come, first-served sites. California State Parks says some sites remain first-come, first-served. They are not in the online inventory.
- Drawings. Certain parks use reservation drawings, which can be entered up to eight months in advance. A site allocated by drawing does not go through the six-month release.
Notifications
ReserveCalifornia's Create Notification feature lets a camper choose dates, facilities and a unit type, and emails them if a matching site becomes available. OpenCampsite is a separate service that watches supported ReserveCalifornia campgrounds and sends a text or email when a check finds a match. With either one, the site is not held, and the booking is completed on ReserveCalifornia.

Questions
- What time does ReserveCalifornia release campsites?
- 8 a.m. Pacific, every day. That release covers the new arrival date six months out. Most sites cancelled the previous day become bookable at 8 a.m. as well.
- I saw a cancellation happen. Why is the site not bookable?
- California State Parks returns most cancelled sites to the reservation system at 8 a.m. on the day after the cancellation, not at the moment of cancellation.
- When do August 29, 30 and 31 open on ReserveCalifornia?
- On March 1. February has no 29th, 30th or 31st in most years, so California State Parks opens those three arrival dates together on the first of March.
- Does ReserveCalifornia notify me when a site opens?
- It has a Create Notification feature that emails you if a site matching your dates, facility and unit type becomes available. The email does not hold the site.
