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.

Floating

Watercraft rentals are available. You can rent canoes, rafts, kayaks and tubes. Rentals include personal flotation devices (PFD), paddles and transportation. Children 12 and under are free for canoe and raft rentals but do count as occupants. You must be 18 years of age or older to rent watercrafts. Short and long floats are available.

The cabins, store, swimming pool and watercraft rentals are operated by your concession hosts, Doyle and Dawn Kennon. Let the Kennons or a member of their staff make your visit to Washington State Park more enjoyable. For reservations or more information about the concession facilities, please call 636-586-2995

The concession stand at the pool features its signature catfish sandwich, hamburgers, cheeseburgers and fries. It is not necessary to purchase a pass for the pool in order to visit the concession stand. The concession stand is open during pool hours.

Fishing

Big River offers you opportunities to catch a wide variety of fish, from catfish and crappie to large and smallmouth bass. The portion of the Big River that extends from the Hwy. 21 bridge to the Meramec River has been designated by the Missouri Department of Conservation as a Smallmouth Bass Special Management Area. Special regulations of length and possession limits apply to smallmouth bass in this area. Regulations are posted at the boat launch and gravel bar in the Big River Day-Use Area.

Picnic Areas

You will have the choice of several picnic areas to enjoy lunch. Picnic tables and grills can be found at the Veteran's Memorial picnic area on the northern end of the park; in a large picnic area on the southern end of the park; near the swimming pool; in Big River Day-Use Area; and near Thunderbird Lodge.
