Lake Erie Islands
Lake Erie Islands tend to be located in the western side of the lake and total 31 in number (13 in Canada, 18 in the U.S.). The island-village of Put-in-Bay on South Bass Island is a major tourism attraction. Kelleys Island has deep glacial grooves left in limestone."[ Pelee Island is the largest of Erie's islands, accessible by ferry from Leamington, Ontario and Sandusky, Ohio. The island has a "fragile and unique ecosystem" with plants rarely found in Canada, such as wild hyacinth, yellow horse gentian and prickly pear cactus, as well as two endangered snakes, the blue racer and the Lake Erie water snake. Songbirds migrate to Pelee in spring, and monarch butterflies stop over during the fall.
