Ginkgo Petrified Forest / Wanapum Recreational Area

 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. 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.
