The 2,981-acre Yellow Creek State Park is in Indiana County along one of the first “highways” in the state, the Kittanning Path. This trail was used by the Delaware and Shawnee nations and by early settlers.

Today, visitors enjoy the sand beach, picnicking, and educational and recreational programs. The 720-acre Yellow Creek Lake is a destination for boaters and anglers. The lake and park are an important rest stop for migrating birds.

The park is named for Yellow and Little Yellow creeks, which flow into the lake. Both creeks contain yellow clay in their banks and bottoms.
