This dive site, "Deep Reef" at Looe Key, is a vibrant natural reef ecosystem within the Florida Keys National Marine Sanctuary. It is characterized by diverse coral formations and serves as a crucial habitat for numerous marine species. As a natural reef, navigation typically involves following the reef lines and contours, often guided by permanent mooring buoys. Looe Key is well-known for its pristine condition and the active conservation efforts in the sanctuary.
Divers visiting Deep Reef can expect to encounter an impressive array of marine life. Notable residents include large Goliath Groupers, barracuda, and various reef sharks. The site also attracts pelagic species passing through, alongside a rich diversity of colorful reef fish and invertebrates thriving among the hard and soft corals.
The best time to visit Looe Key for diving is generally year-round, though summer and early fall offer calmer seas and warmer waters. These months are also ideal for potentially witnessing Goliath Grouper aggregations. This shallow and generally mild-current reef is highly suitable for both scuba divers of all levels, including beginners, and is also an excellent spot for snorkelers and freedivers due to its accessible depths and abundant marine life.
