Cowan Lake State Park

Cowan Lake State Park is a protected natural area in Ohio featuring a large lake surrounded by beech and maple forests. The grounds include hiking trails, camping areas, and facilities for boating and fishing throughout the year.

The land was originally inhabited by Miami and Shawnee peoples until regional conflicts in the late 1700s opened it to European settlement. It later became a protected park to preserve its natural resources for public use.

The park serves as an educational center where visitors study fossils embedded in limestone formations that date back to ancient inland seas.

Visitors can find information about trails and boat rentals at park entrances and access points. The best time to visit is spring through fall when all facilities and services are fully operational.

The park maintains specific areas for observing rare American lotus flowers and provides designated zones for muskellunge fishing in the lake.
