Chun Zumbul Deep

Chun Zumbul Deep is a Cozumel site we come back to, especially during bull shark season. It isn't always on the main itineraries, which makes it feel a little more special. You're drifting along, usually with a decent current, over these sandy dunes that separate three distinct coral plateaus. We love the way the light plays on the sand here, casting long shadows. It’s not just a flat drift; you’re navigating the contours of the reef. We’ve seen some incredible things here: American eels snaking out of the sand, and once, a fleeting glimpse of a little post horn squid, which was a real treat. French grunts school densely, shimmering in the flow. During the right time of year, from November to March, the bull sharks are the main draw. Seeing those powerful animals cruise by, unperturbed, is a rush. Keep an eye out for fringed filefish hovering near the coral. This site is definitely for divers comfortable with a good current and looking for something beyond the usual Cozumel suspects.
