One of Wisconsin’s top destinations Lake Geneva was formed 20,000 years ago as glaciers traveled across North America. Over 7 miles long from east to west and 2 miles wide, Geneva is home to a wide variety of fish. Crystal clear water and large minnow populations cause excellent growth rates. Large fish of all species are present in Lake Geneva. Beautiful and historic mansions line the shoreline. There is so much to see and do on beautiful Lake Geneva.
