Vilas County is home to one of the largest concentrations of freshwater lakes in the world. These lakes were left behind by glaciers that covered the region thousands of years ago. Some of the lakes are small; others cover thousands of acres. They are all spectacular. To truly experience the beauty of the region, consider getting out on the water. If you want to pilot your own boat (captain’s hat recommended but not required), check out this boating information. A certification is required for anyone who’s at least 16 years old and born after Dec. 31, 1988, who wants to operate a motorboat or personal watercraft. Some of the most scenic lakes in Vilas County include Trout Lake south of Boulder Junction, Lac Vieux Desert in northeastern Vilas County and Presque Isle Lake.
