The Apostle Islands were named by a pious French explorer, who thought there were twelve islands (there are actually quite a few more). They are all part of a the Apostle Islands National Park, with the exception of Madelaine Island. Madelaine Island has homes, stores, and fine dining. One can visit any of the islands, although permits may be required and a few remaining long-term private leases are still in force. The sea caves of the Apostle Islands are famous and splendidly beautiful. Carved from red standstone layers by ice that is carried by waves like a battering ram, they form circular caverns. Kayakers love them in the summer. In winter, you can walk into them on the deep ice.
