    StandoutExceptional marine biodiversity

    We usually head to Caye Caulker Marine Reserve when we want a relaxed dive with plenty to look at without having to work for it. It’s a shallow spot, topping out around 17 meters, which makes for long bottom times and great natural light. Sunlight filters through the water column, hitting big formations of great star coral and grooved brain coral, making them glow. We’ve had incredible luck with juvenile fish here – tiny blue doctorfish darting amongst the polyps, little hogfish hovering near the sand. It’s not a place for huge pelagics, though we did once spot a very curious barracuda following us for a good ten minutes. What you’ll find are healthy reefscapes, some impressive elkhorn, and a steady stream of Caribbean regulars like parrotfish and small groupers. We’d suggest this site for anyone looking for an easy, pleasant dive, maybe even a nice second dive after something deeper. Visibility is usually consistent, around 17 meters, which is plenty to soak in the details.
