Why dive here
With 177+ marine species recorded in the area - including barracuda, bull sharks, dolphins, eagle rays and nurse sharks - Colombia Deep offers some of Cozumel's richest diving. Water ranges 27-30°C, warmest August, September, October.
Colombia Deep is where Cozumel really shows its teeth. We're talking dramatic, towering coral formations that feel like underwater cathedrals, dropping off into the blue. The currents here can be robust, so it's one for experienced divers who enjoy a drift and know how to manage their buoyancy when the water moves. We love dropping in and letting the current carry us past those huge pinnacles, often spotting Graysby tucked into crevices and Yellowhead Wrasse darting through the coral. Keep an eye out for the Splendid Toadfish; they’re often hiding under ledges. The visibility is usually excellent, giving you that 'flying through space' sensation as you look down into the deeper sections, making it one of our favourite deep drifts on the island.
Safety Notes
Strong currents typical this month (avg 79 cm/s). Good buoyancy control essential.
