Cadillac, a lakefront community in northern Michigan, is surrounded by Lake Mitchell and Lake Cadillac. The two lakes are linked by a manmade canal, originally used by lumbermen to float timber, but now used for fishing and boating. Visitors venture to the nearby Huron-Manistee National Forest to hike, camp and bike. Adventure Island is another attraction to enjoy in the area as it has waterslides and miniature golf. Located in Mitchell State Park, Johnson Hunting and Fishing Center exhibits a marsh display and a wall-size aquarium filled with local Michigan fish. Among the major events in the area are July's Keweenaw Trail Running Festival and the Grand Island Trail Marathon as well as October's Chestnut Harvest Festival, where visitors learn all about the chestnut and taste chestnut-based cuisine. Other activities include canoeing and camping at the Pine and Manistee Rivers as well as hiking, skiing and snowmobiling at Cadillac Pathway, McGuire's Resort and Caberfae Peaks, one of Michigan's best skiing areas.
