An 11-foot-high "glacial erratic" boulder known as Dighton Rock once rested on the shore of the Taunton River adjacent to this park. Covered with petroglyphs, carved designs of ancient and uncertain origin, the rock is now installed in a small museum. The museum (open by appointment) exhibits several explanations of the carvings, which range from Portuguese explorers to Native Americans.

The park, which covers 85 acres in the town of Berkley, is a popular local picnic spot because of its soft, grassy areas interspersed with mature shade trees.
