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.
For larger groups, there are two open shelters available for use. A shelter with capacity of 96 people is located in the Big River Day-Use Area. Another shelter with capacity of 84 people is located across from the petroglyph site. They may be reserved for $40 each per day. A small gazebo overlooking the Big River can be reserved for $25 per day. To reserve a shelter, contact the park to check for availability by calling 636-586-5768. If available, fill out the Shelter Reservation Application and mail it to the park for approval. Submission of this application does not guarantee reservation of the shelter.
If not reserved, the shelters are available at no charge on a first-come, first-served basis. Restrooms and potable water are available near the two open shelters from April through October. No electricity is available. Parking at the shelters is limited to the designated spaces. Please do not park on the grass. Alcohol consumption and/or possession is not allowed in the Big River Day-Use Area (including the shelter and undesignated swimming area) or at the scenic overlook (including the gazebo).
