Devil's Throat - Cozumel

Devil’s Throat. Just the name tells you this isn’t some gentle drift. This is Cozumel’s signature dive, the one everyone talks about, and for good reason. We love how it starts with that tight squeeze at 25 metres, a narrow chimney dropping straight down. You feel the rock pressing in, the light fading above, then suddenly it spits you out onto the big blue wall around 40 metres. It’s not just the dramatic topography; the wall itself is often a highway for larger stuff. We’ve seen spotted eagle rays glide by, their shadows passing over us. Look for big reef sharks too, cruising the deeper currents. This dive isn't for the faint-hearted or those new to deep diving, but if you’re comfortable with depth and confined spaces, it’s an absolute thrill. Our tip: go first thing in the morning to beat the crowds and catch the best light filtering through the reef openings before you drop into the dark.
