Introduction

Ginkgo Petrified Forest State Park is a perfect spot for rigs with plenty of shoreline along the Columbia River, an ancient forest, and 50 full hookup campsites for RVs. Located in Vantage, Washington, the state park is situated within the larger 7,124-acre Wanapum Recreation Area along the western shoreline of Wanapum Reservoir on the Columbia River. The petrified forest contains more than 30 species of petrified trees including ginkgo, sweetgum, redwood, yew, maple, and cottonwood. The first specimens were found by Frank Walter Bobo in 1894, and in 1938 the first museum was constructed by Civilian Conservation Corps (CCC) workers. The Ginkgo Petrified Forest is listed by the National Park Service as a U.S. National Natural Landmark. In 1963, construction on the Wanapum Dam was completed along the Columbia River, and now Wanapum Recreation Area offers 27,000 feet of freshwater shoreline for campers to enjoy.

The first inhabitants of the area were the Wanapum Indian Tribe. Over the years, the tribe was responsible for carving more than 300 petroglyphs in the surrounding basalt cliffs along the Columbia. The tribe used the petrified wood for making arrowheads, spear tips, and more. The tribe first encountered European settlers when the Lewis and Clark Discovery Expedition entered the region.

Today, Ginkgo Petrified Forest State Park and Wanapum Recreation Area offer plenty of exciting activities that include water sports, fishing, and hiking.
