California's state park and coastal beach campgrounds are some of the hardest reservations in the country, and they don't go through recreation.gov — they run on ReserveCalifornia, with its own release window and its own quirks. Knowing how that window works is most of the battle.
ReserveCalifornia opens inventory on a 6-month rolling window: each morning, the date exactly six months out becomes bookable, releasing at 8:00 AM Pacific. To camp a particular Saturday, you need to be online at 8am Pacific six months to the day beforehand. For the famous coastal parks, the desirable sites can be gone in well under a minute.
The single most common way people lose a site is spending release-morning minutes creating an account or typing in payment details. Register in advance, sign in several minutes early, and have your park, dates, and vehicle/occupancy details decided. Treat 8:00 AM as a hard start, not an approximate one.
Unlike some federal campgrounds where you reserve a site type, ReserveCalifornia generally has you pick an individual numbered site. That's worth preparing for: look at the campground map beforehand and write down a ranked list of three or four acceptable site numbers, because your first choice will often be taken the instant you click. Check the listed length limit and hookups if you're in an RV — see our RV camping list.
Six-month-out booking guarantees over-booking, and plans change constantly between then and the trip. Because ReserveCalifornia charges a cancellation fee, a wave of releases lands as that deadline approaches, with a second wave in the final days — the same pattern covered in our cancellation timing guide. CampSage watches California state park and beach campgrounds for exactly this: set a free opening alert and check the live map for 🔥 just-opened sites.
Big Sur, the coastal beaches and the marquee parks absorb almost all of the demand. Parks 30–60 minutes inland or one notch less famous often have availability on the same weekend. Browse every California campground CampSage tracks and set alerts on several at once rather than betting everything on one park.

No. State parks and state beaches book through ReserveCalifornia; recreation.gov handles federal sites like national forest and national park campgrounds.
Set a free cancellation alert. Sites booked six months out get released regularly, especially around the cancellation-fee deadline, and CampSage emails you the moment one reopens.
