6. Lake Superior, Michigan
Of course Lake Superior is on this list. Not only is this the world’s largest fresh lake by surface area, it also has a 2,700-mile long shoreline that is speckled with natural sights like 200-foot high sandstone cliffs, beaches, waterfalls, the Apostle Island sea caves, and the rugged Isle Royale. You can merely stand on the beach and take in the beauty, or you can hike, drive, and kayak throughout the protected areas around Lake Superior.
