Merkle Wildlife Sanctuary features hiking through poplar forests, a 4.3 mile self-guided driving tour and fishing in five ponds that are stocked with large mouth bass, blue gill, and various other species. The Frank Oslislo Visitor's Center has interpretive displays, a live animal exhibit, children's activities and a bird viewing area. The park includes large manmade mounds of dirt called "ha-has". Their purpose is unknown, but they are believed to be either early boundary markers or defenses built by soldiers in the War of 1812.
