The Beaver Dam State Park trailer camping area has electricity at each pad and a sanitary dump station. A shower building with flush toilets is located in the center of the trailer camping area. Water is available, but individual sites do not have water hookups. There are 40 reservable campsites; all others are first come-first served. Tent camping is in a separate area, with nearby restrooms and water. A designated area for youth-group camping, such as Boy or Girl Scouts, features rest rooms, water, fire pads and picnic tables. When youth groups plan to use the area, make a reservation using the ExploreMoreIL website.
All camping is situated in wooded areas with large oak and hickory trees which provide shade throughout most of the day. Located next to the shower house is a Rent A Cabin, available for reservation. The Rent-A-Cabin and many campsites are available for reservation using the ExploreMoreIL website. The park does not rent tents.
