About Islamorada Dive Center
Islamorada Dive Center is a full-service PADI dive resort based at the Three Waters Resort & Marina (the former Postcard Inn at Holiday Isle) at mile marker 84 on Windley Key. The shop runs daily two-tank dive trips to the reefs and wrecks of the Upper Keys, with the boats leaving from the marina just steps behind the dive shop.
The local dive menu is one of the best in the Keys. Alligator Reef and its historic lighthouse sit a short run offshore, packed with tropical fish, rays, and resident goliath grouper, while the Eagle wreck gives advanced divers a 287-foot ship resting in deeper water. Snorkelers are welcome on many reef trips, and the classroom and pool programs run the full PADI ladder from Discover Scuba and Open Water through advanced, rescue, and specialty courses, with nitrox fills and a stocked retail shop on site.
The resort setting is the differentiator: divers can stay, eat, and dive in one place, and dive-and-stay packages bundle rooms with boat trips. With daily departures, small-boat convenience, and instructors used to turning nervous first-timers into certified divers, Islamorada Dive Center is the natural base for underwater time in the Upper Keys.
