Why dive here
With 177+ marine species recorded in the area - including barracuda, bull sharks, dolphins, eagle rays and nurse sharks - Media Luna offers some of Cozumel's richest pinnacle diving. Water ranges 27-30°C, warmest August, September, October.
Media Luna often gets overlooked for Cozumel's flashier drift dives, but we think that's a mistake. This crescent-shaped coral head, sitting on a flat expanse of white sand at just 14 metres, is pure joy for a slow, observant dive. Forget the fast current; here you drift gently, or often not at all, allowing you to really get up close. We love Media Luna because it’s a masterclass in small wonders. Drop down and you’ll see the reef forming a perfect half-moon, a natural amphitheatre for activity. Look for the tiny Notchtongue Gobies perched on the coral, their eyes swivelling. Rosy Blennies peer out from their hidey-holes. The staghorn coral here is healthy, a vibrant backdrop for groups of yellowfin grunt that hang out in the shade. On the sand flats, keep an eye out for Haller's round rays, often half-buried, or the Atlantic Lookdowns, their flat, reflective bodies catching the light. It's a photographer's dream, especially with a macro lens, and perfect for newer divers looking to build confidence without battling a strong push.
