This island in Lake Erie offers entertainment, history and vacation appeal during the summer season. One of the best known attractions is the Antique Car Museum, which showcases a collection of Model T Fords and vintage snowmobiles. Watch them in a parade every Sunday afternoon. South Bass Island is home to the world's largest geode, called the Crystal Cave, on the grounds of Heineman's Winery, which has been making wine on the island for more than a century.
