Clark Reservation State Park is a geologic wonder of the last ice age and a botanist's paradise. The park's natural features include rugged cliffs and rocky outcrops, woodland and meadow, a wetland and a glacial plunge basin lake in which the surface waters and bottom waters do not mix. Fishermen can catch pickerel, bullheads and sunfish; while birdwatchers may observe cedar waxwings, kingfishers and woodpeckers. Guided nature walks leave from the Nature Center building, which also offers numerous exhibits. Hikers may choose from five trails, including the cliff trail, which has a ledge overlook 175 feet above the water.
