East Harbor is situated on a peninsula stretching into the waters of Lake Erie. The park also lies on the fringe of Ohio’s prairie marsh zone. These wetlands are remnants of the Great Black Swamp, which once covered an area 120 miles long and 30-40 miles wide. Nature enthusiasts enjoy viewing an abundance of waterfowl and shorebirds in the park’s scenic wetlands, as well as from the swimming beach and picnic areas along the lake. East Harbor also offers a large campground and great boating, hiking, and fishing amenities.
