Tohickon Creek flows through the 45-acre Ralph Stover State Park, making a scenic picnic area. The nearby High Rocks section of the park is a lovely overlook of the Tohickon Creek.

Early inhabitants of the area, the Lenni Lenape, named the creek ?To-Hick-Hanne? meaning ?Deer-Bone-Creek,? leading to the modern name Tohickon Creek.

Early industry depended on Tohickon Creek. Ralph Stover State Park marks the site of a late 18th century water-powered grist mill. The park takes its name from Ralph Stover who owned and operated the mill. Remnants of the mill, and the millrace, which diverted the water from above the dam to power the mill, are still visible.

In 1931, the Stover heirs gave this property to the Commonwealth for use as a state park. Recreational facilities were first opened in 1935 after development by the Federal Works Progress Administration (WPA).

The property known as the ?High Rocks? was added through the donation of the late James A. Michener, a noted author. This area is popular for its spectacular views and geological features and is used extensively as a rock-climbing site. The 200-foot sheer rock face of this cliff offers a unique challenge to the experienced climber.

There are no entrance fees or day use fees for any state park in Pennsylvania.
