Black Hawk State Park beach

Lake · Iowa

About this swimming hole

Black Hawk State Park sits on the southernmost glacial lake in the United States, a 957-acre natural lake with no motor-size restrictions. Swimmers get two unsupervised options: a beach at the east end of the campground and Denison Beach along the north shore. The 33-mile Sauk Rail Trail starts near the park, so the beach pairs easily with a long bike ride.
