Lake Okeechobee offers a unique experience as Florida's largest freshwater lake and the tenth-largest in the U.S. It spans 730 square miles but is only about 9 feet deep, it’s too vast to see across and is fed primarily by the Kissimmee River. The lake touches Glades, Okeechobee, Martin, Palm Beach, and Hendry counties, all meeting near its center. Historically, the Calusa called it "Mayaimi," meaning "big water." The name "Okeechobee" comes from Hitchiti words for "water" and "big".
