Getting a campsite at Sonoma State Historic Park

How do I get a campsite at Sonoma State Historic Park 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 Sonoma State Historic Park 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 Sonoma State Historic Park?

California State Parks campgrounds, including Sonoma State Historic Park, 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 Sonoma State Historic Park?

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 Sonoma State Historic Park.

No. ReserveCalifornia has no waitlist or notification feature. When a site at Sonoma State Historic Park 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.
