Why campsites open up at San Gregorio State Beach

California's refund rules create a predictable wave of cancellations. Because campers lose money if they cancel late, most drop their reservations right before the refund deadline — which means openings cluster about a week out from any given date.

2–6 days beforeFirst night's fee forfeited; the rest refunded, minus the fee
Under 2 days / no-showNo refund — all fees forfeited

Getting a campsite at San Gregorio State Beach

How do I get a campsite at San Gregorio State Beach when it's sold out?

Cancellations happen constantly — the trick is being first to know. Set an alert for your dates and we'll watch San Gregorio State Beach on ReserveCalifornia around the clock, then notify you the moment a site opens. Alerts run on a Pro subscription ($9.99/mo, cancel anytime).

How far ahead can I book San Gregorio State Beach?

California State Parks campgrounds, including San Gregorio State Beach, are reservable up to 6 months in advance on a rolling daily window — each new date becomes bookable exactly six months out, released at 8:00 a.m. Pacific Time. Peak summer and holiday dates at popular parks can sell out within minutes of release.

When do campsites usually open up at San Gregorio State Beach?

Openings are driven by California's cancellation policy. Campers get a full refund (minus the fee) only if they cancel 7+ days before arrival; cancel 2–6 days out and they forfeit the first night; under 2 days there's no refund. That refund cliff produces a predictable wave of cancellations around 7 days before a date — the best window to catch an opening at San Gregorio State Beach.

No. ReserveCalifornia has no waitlist or notification feature. When a site at San Gregorio State Beach is cancelled it simply returns to inventory at full price, first-come, first-served — whoever books it first gets it. That's exactly why an alert service exists.
