The southern hospitality and charm of Kentucky are found from the heights of Appalachian Kentucky to the placid water of Lake Cumberland, the forests and falls of Daniel Boone Country and the subterranean depths of Mammoth Cave. The natural wonders of Kentucky are punctuated with two metropolitan cities. Lexington, the heart of Bluegrass Country, is rich with state history and heritage. Louisville hosts the Kentucky Derby, an event started in 1875, with two weeks of festivals and entertainment in May each year. Treasures such as grand mansions, historic sites and legendary horse farms are spread throughout the Bluegrass State. The Constitution Square State Historic Site in Danville is the birthplace of Kentucky's statehood and features historic homes and monuments. Western Kentucky allows visitors to experience sports and recreation in a natural setting, while Northern Kentucky offers easy access to the metropolitan centers of Lexington, Louisville and Cincinnati, Ohio. In the state, hike, golf, bike, climb, sight see, explore underground caves, ride horses, canoe, raft, swim or visit historical sights—the opportunities for adventure and relaxation are endless.
