Key Biscayne is also home to one of Florida’s first and most exciting marine attractions, the Miami Seaquarium. Constituting an exotic oasis spanning 38-acres and featuring eight different marine animal shows daily, the Miami Seaquarium is a must-see by both visitors and residents to the island. The Miami Seaquarium’s newest exhibit, Dolphin Harbor, will add to the further delight of audiences as guests will have the opportunity to interact with dolphins firsthand.
