Ginkgo Petrified Forest State Park
About 30 miles east of Ellensburg via Interstate 90, Ginkgo Petrified Forest hugs the western bank of the Columbia River and preserves the remarkable petrified-wood logs that were once part of a thriving ginkgo forest. The 1¼-mile Trees of Stone Interpretative Trail loop trailhead and Trailside Museum are a 2-mile drive west of the interpretive center (closed Monday through Thursday, mid-September–mid-May). The adjacent Wanapum Recreation Area has camping, swimming, and river access for boaters.
