Looe Key National Marine Sanctuary - Florida Keys
Looe Key is a great spot if you’re looking for a relaxed, shallow dive in the Florida Keys. The reef sits at a comfortable 9 metres, making it perfect for beginners or anyone who just wants to take it easy and soak up the sun. We’ve had some lovely drift dives here, spotting barracuda hanging out in the current and often coming across parrotfish munching on the corals. It’s a cheerful, accessible reef, and an easy day trip from Key West.
