Islamorada is a REEF surveyor's paradise, offering spectacular sites that are brimming with diversity, such as Alligator Ledge and the Wreck of the Eagle. Advanced surveyors may challenge themselves to identify 100 fish species on a single dive, while those who are just beginning to conduct REEF surveys will be able to foster their Tropical Western Atlatic fish id knowledge under the guidance of Expert Level Fish ID Surveyors, Carlos and Allison Estape. When topside, enjoy the laid-back island vibe of the Postcard Inn while participating in educational fish id seminars each evening. Join this trip and see for yourself why the Florida Keys are called the "Diving Capital of the World!"

An optional, but highly recommended, day-trip to Blue Heron Bridge is available for an additional fee.
