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. The park was set aside as a historic preserve when remains of a fossil forest were unearthed during highway construction in the 1930s. Petrified wood from many different trees are common in the area, but specimens of petrified Ginkgo are rare. Many buildings on the premises owe their origin to the work of the 1930s Civilian Conservation Corps.

Ginkgo Petrified Forest State Park is a 2020 Park Improvement Project grant recipient.
