Why dive here
With 87+ marine species recorded in the area - including bull sharks, dolphins, hammerhead sharks, seahorses and sea turtles - Christmas Tree Cave offers some of Florida Keys's richest cave diving. Water ranges 19-32°C, warmest July, August, September.
Christmas Tree Cave sits at a shallow 12 meters, making it a good spot for newer divers looking to explore an overhead environment. It’s more of an overhang than a true cave, allowing natural light to filter in and illuminate the interior. You'll find plenty of small reef fish taking shelter, tucked into crevices. It's a quick dive, usually done as part of a longer trip.
