Washington State Park

Park Information

While parks and historic sites are open for day-use, capacity will be monitored closely in order to prevent overcrowding. If nearing capacity, parking lots may close temporarily. Missouri State Parks has implemented a number of measures designed to maintain required social distancing and protect visitors, volunteers and staff. The latest information from Missouri State Parks on COVID-19 can be found here. A full list of temporary closures can be found here.

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. Hikers can choose from three rugged hiking trails. Buildings constructed by African American Civilian Conservation Corps stonemasons complement the park and add to its sense of history.
