The stretch of the Intracoastal Waterway that serves as the western boundary of Gumbo Limbo Nature Center is known as Lake Wyman. In the days before the dredging of the Intracoastal, Wyman was one of three mainly freshwater lakes connected together by a river within a vast sawgrass marsh. Lake Wyman and all of the Intracoastal is now saltwater and home to myriad saltwater species. This spot at the north end of Gumbo Limbo allows access to the lake and is used for a variety of hands-on programs that teach kids about life in the lake. BACK TO THE BEGINNING.
