    Punta Sur’s Devil’s Throat is where Cozumel really earns its stripes, a proper adventure dive for those with a few logs in their book. We’re talking about a narrow, downward-sloping cavern that starts around 27 meters and spits you out much deeper. The entry itself is a squeeze, and then you’re navigating tight passages, feeling the rock close around you before it opens into a truly grand cathedral-like space. That moment when you emerge into the light, often with a school of fusiliers swirling past, is pure magic. Visibility here is usually excellent, around 27 meters, which is a blessing because you want to see every detail of those reef sharks and eagle rays that often cruise by the cavern’s exit. While you’ll spot plenty of Goldspot Gobies and Sharpnose Pufferfish tucked away, the real draw is the geology and the thrill of the journey. It's not a relaxed drift, so save this one for when you’re comfortable with your buoyancy and ready for a serious current.

    Safety Notes

    Strong currents typical this month (avg 79 cm/s). Good buoyancy control essential.
