What's holding you back? Ginkgo Petrified Forest State Park Interpretive Center was made to be experienced.
It's situated in Ellensburg, an estimated 140 miles (225 kilometers) from the state capital, Olympia.
Be sure to look into accommodation possibilities before you set out, since there aren't any hotels in the vicinity. Why not ask about rooms 55 miles (89 kilometers) away at the Icicle Village Resort? If that doesn't suit you, try the Towneplace Suites Richland Columbia Point, 60 miles (97 kilometers) away, or the Sleeping Lady Mountain Resort, 50 miles (80 kilometers) away.
