Ginkgo Petrified Forest / Wanapum Recreation Area
Did you know that petrified wood is Washington’s official state gem? Considered one of the most diverse fossil forests in North America, Ginkgo Petrified Forest State Park is famous for its rare specimens of petrified Ginkgo tree discovered there in 1932.
Curious? Drive to the park interpretive center and take in the big skies, Columbia River views and outdoor exhibits of petrified wood. Look for evidence of Ice Age floods carved into the walls of the Columbia River Gorge. Then step inside the Ginkgo Petrified Forest Interpretive Center. Not only is it air-conditioned, the museum features more than 30 varieties of petrified wood, including a display of rare ginkgo petrified wood.
Drive the Old Vantage Highway to the Ginkgo "trailside museum," constructed by the Civilian Conservation Corps in the 1930s, and recently updated with a new interpretive exhibit. From here, the Trees of Stone Interpretive Trail winds past more than 20 petrified logs in their original settings. Birders, look for golden eagles, sage thrashers, Say’s phoebes and many other species. Elk and bighorn sheep also frequent this area.
You may want to reserve a campsite at nearby Wanapum Recreation Area so you can cap off a hot day with a refreshing swim or boat float in Wanapum Lake (a reservoir on the Columbia River). Pitch your tent or connect your RV, make a picnic under a shady tree, and savor this green oasis.

Reservations & fees
The park is home to the Vantage Forest, one of the most diverse groups of petrified wood species in North America. Local Native American tribes used this petrified wood for making tools.
Professor George Beck recognized the site’s geological significance. Upon his 1932 discovery of a rare petrified Ginkgo log (Ginkgo biloba), Beck led efforts to set aside this remarkable forest and preserve it. In 1935, as part of a grand vision to establish the site as a National Monument, Ginkgo Petrified Forest State Park was born.
During the midst of the Great Depression, emergency work relief funds were used to protect and develop the park. Between 1934 and 1938, Civilian Conservation Corps enrollees, as well as local emergency work relief laborers, built much of the park infrastructure we see today, including ranger residences, an interpretive center, and a trail-side museum and trail system. In 1965, the park was formally registered as a National Natural Landmark.
Construction of the Wanapum Dam in 1963 silenced the waters of the adjacent Columbia River. To enhance public access, state park management was expanded in 1974, and most recently in 2012, to provide overnight and day-use facilities along the shores of the Wanapum Lake.
