Ojo de Agua - Cozumel

Robyn’s Reef on St. Vincent is a reliable drift dive, the kind you settle into easily. We often start at Flat Rock, which, as the name suggests, is a good spot to scan for frogfish if you’re patient. From there, it's a gentle ride down the slope. It’s not a frenetic dive, more a slow reveal. The reef here has some pretty substantial azure vase corals, really eye-catching against the sponges. We've seen good numbers of French grunts and blue creole wrasse. Keep an eye out for queen triggerfish too, they’re usually patrolling the deeper sections. While the drift is relaxing, there’s enough action with the Jacks and Snappers to keep things interesting. It maxes out around 23 metres, so it’s a good one for intermediate divers. The visibility averages 16 metres, which is decent enough for wide views of the corals and schooling fish. It’s a good choice if you're looking for a comfortable dive with consistent marine life, especially in the late morning when the light hits the reef just right.
