In waters just beyond the Florida Keys, this delicate reef seeps into Biscayne National Park, among others, and is made up of more than 50 species of coral. A range of glass-bottom-boat and snorkelling tours explore its various parts, but be sure to do your research before you set out – the Keys Diver and Snorkel Tours, which operate from Key Largo, are a reputable option.
Biscayne National Park in the Florida Keys holds many a natural and man-made treasure – and the island of Boca Chita, with its historic lighthouse and gentle hiking trail, remains one of the most popular spots. From the lighthouse’s 65-foot observation deck, you can drink in views of the ocean, surrounding islands and downtown Miami. Other park highlights include the Maritime Heritage Trail, an underwater course of marine life and shipwrecks, and the precious Florida Reef.
