About this swimming hole
A long sweep of sand along the Keweenaw Peninsula, Great Sand Bay is the classic Lake Superior roadside swim stop. Park right off the road, walk the length of the beach, and settle in for a chilly but gorgeous dip. The shallow entry and wide open shoreline make it an easy, low-commitment Superior swim.
