Swimming Pool and Concession Stand
Cool off in the park's swimming pool. The pool features a concession stand that sells cold drinks, snacks, ice cream and other food items. It is not necessary to purchase a pass for the pool in order to visit the concession stand.
The cabins, store, swimming pool, concession stand and watercraft rentals are operated by the park concession, BA Services Inc. Please visit their website or call 636-586-2995 for more information about these services, including seasons and hours for the pool and concession stand.
Big River
Swimming is also permitted in the Big River. There are no lifeguards on duty along the river, so swimming here is at your own risk.
