Trails wind throughout the park and are accessible from North Main St., just across from Lakeshore St. on the southwest side of the street. Bluffs has a variety of natural features including an oak-hickory forest, wooded ravines, and an open field with remnant prairie species. There are also a few examples of large older trees including open grown oaks and a huge white ash. This area has long been a favorite place for bicycles, but hikers are also sure to enjoy the rugged trails throughout the park.
