Why dive here
With 177+ marine species recorded in the area - including barracuda, bull sharks, dolphins, eagle rays and nurse sharks - Colombia Reef offers some of Cozumel's richest wreck diving. Water ranges 27-30°C, warmest August, September, October.
Colombia Reef gives you a real taste of Cozumel’s drift diving. We love dropping in on the shallower section, around 12 to 15 metres, where the light just floods the coral. You’ll spend most of your dive letting the current gently push you along, hardly finning at all. Keep an eye out for those big barrel sponges and the occasional spotted eagle ray gliding past in the blue. The deeper wall, down to 22 metres, has some fantastic swim-throughs. They’re not tight squeezes, more like open archways in the reef, just big enough to make you feel like you’re exploring something secret. We’ve seen huge schools of grunts hanging out in the overhangs there, practically blocking the way. Our favourite time to dive Colombia Reef is first thing in the morning; the boat traffic is lighter, and the reef feels a bit more vibrant before the crowds arrive. This site is perfect for anyone comfortable with a moderate drift, offering plenty to see without needing to fight the flow.
