In the waters near Grand Island, 30 ships have gone down—most during November storms between 1860 and 1929. Though half of the ships are still missing, the clear, cold waters have preserved the found ones well. Want to peer in the water without getting wet? Take a glass-bottom boat tour out of Munising. A two-hour, narrated cruise takes you over three shipwrecks on Lake Superior’s floor, as well as by the East Channel Lighthouse and rock formations of Grand Island. The tours run until mid-October, weather permitting. Reservations recommended, 906-387-4477, shipwrecktours.com.
