If you have not had the pleasure of experiencing Turnip Rock via Lake Huron, we insist that you head there immediately. This enormous rock received its turnip connotation from thousands of years of erosion from storm waves. Now, it's an island with a few trees and little other vegetation. The land nearby is all privately owned, so the only way to view it is by kayak or trekking across frozen Lake Huron in the winter. While in the Port Austin area, be sure to check out Port Crescent State Park, one of three dark sky preserves in Michigan, where you can catch a glimpse of the Northern Lights.
