Pukaskwa National Park

Some of the most pristinely preserved Great Lakes wilderness, Pukaskwa National Park is one of the most beautiful stops on Lake Superior. Soak in the sun and relax at the world-famous Horseshoe Bay. However, don't be fooled. The crystal-clear turquoise waters may look tropical and inviting, but the water in Lake Superior averages a bracing 4°C, or 39°F, year-round.
