Beautiful Washington State Park is located on the border of Jefferson and Washington County, right off HWY 21. Just a short drive from St. Louis.
We have fun activities for the whole family. Short day hikes on our Ozark trails, swimming at the pool, spend time at the petroglyphs, fish, swim, float the Big River, or just enjoy a hand dipped ice cream at Thunderbird Lodge while you relax to the sounds of the river.
