About
Ginkgo Petrified Forest State Park is a 7,470-acre park with camping at Wanapum Recreational Area. The park features 27,000 feet of freshwater shoreline on the Wanapum Reservoir along the Columbia River. Ginkgo Petrified Forest, discovered in the late 1920s, is a registered national natural landmark.
Is Wanapum State Park fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
CampHawk watches Wanapum State Park in Vantage, WA for you. We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification, with a link straight to the booking page.
Searching is free and needs no account — the calendar above is live right now. Watching Wanapum State Park for cancellations is the paid part.
