Ginkgo Petrified Forest / Wanapum Recreational Area

Ginkgo Petrified Forest State Park is a 7,470-acre park with year-round camping at Wanapum Recreational Area. The park features 27,000-feet of freshwater shoreline on the Wanapum Reservoir on the Columbia River. Petrified wood was discovered in the region in the early 1930s, which led to creation of the park as a national historic preserve. Ginkgo Petrified Forest is a registered national natural landmark. It is regarded as one of the most unusual fossil forests in the world.

Discover Pass: 
A Discover Pass is required for vehicle access to state parks for day use. For more information about the Discover Pass and exemptions, please visit the Discover Pass web page.

Wanapum State Park closed until further notice
Effective Monday, April 28, Wanapum State Park will be closed due to a fracture in the structure of Wanapum Dam. Grant County Public Utility District has closed all beaches and water access in the area above the dam, which includes Wanapum State Park, to protect sensitive cultural resources and help to ensure public safety. Because water access is integral to the park and a primary focus for visitors, all access to Wanapum State Park will be closed until further notice. 

Full refunds will be provided to campers with reservations at Wanapum State Park for dates through September 15, 2014. State Parks reservation system operators are calling these customers to inform them of the cancellation and to process refunds; call 888-226-7688 to reach the call center. 

Gingko Petrified Forest Interpretive Center, part of the Wanapum area, remains open for day use.

Interpretive Opportunities
The Ginkgo Petrified Forest Interpretive Center offers spectacular views of the Columbia River, Sentinel Gap and surrounding Ice Age flood-carved basalt landscape. Indoor exhibits tell the geologic story of the Vantage Petrified Forest and display one of the most diverse petrified wood collections in North America. Admission is by donation.

The Trees of Stone Interpretive Trailhead, located two miles west of the interpretive center, guides you through an ancient fossil bed with nearly two-dozen petrified logs exposed along this one-mile loop trail. Along the trail you also will find ice-rafted erratics remaining from Ice Age floodwaters thousands of years ago.
