Washington State Park

Park Information

Petroglyphs, quaint hiking shelters and incredible Ozark overlooks define the Washington State Park experience. Easy access to the Big River makes the park great for swimming or fishing and the park’s three hiking trails address every type of hike, from easy strolls to power hikes. Buildings constructed by African-American Civilian Conservation Corps stonemasons complement the park and add to its sense of history.

Name that Trail: This trail is designed especially for people with visual or physical disabilities and is designated as a National Recreation Trail. The trail passes by a quarry pond, which now supports a variety of animal life. A short spur off of the trail takes hikers to the top of the granite outcrop, where they can explore the maze of giant elephant rocks. A second spur brings you to a point overlooking an old quarry site, where Missouri red granite was quarried from the 1860s through the early 1900s. Don’t know the answer?
