Composed of 855 acres of forested land in Deer Creek Valley, Rocks State Park is dotted with a number of large boulders that give the park its name. Popular activities in the park include hunting, fishing, and tubing on Deer Creek, and there are also 3.5 miles of scenic hiking trails for visitors to enjoy.

Several day use picnic areas offer picnic tables, grills, public washrooms, and children's playground equipment; visitors should note that a small service fee must be paid to use these facilities. Large picnic pavilions can be rented out by large groups for weddings and other special events.
