With today being a holiday for some people, they may have enjoyed a three day weekend and could take a ferry ride over to Madeline Island, the largest of the Apostle Islands, and doing a little exploring.
Ferry Ride
At the tip of the Door Peninsula, the Washington Island Ferry provides a way for vehicles and passengers to reach Washington Island, a 22 square mile island in Lake Michigan about seven miles from the tip of the peninsula. Another ferry takes passengers from Washington Island to Rock Island, a 912 acre state park were vehicles are not allowed to be brought over to the island.
