Why dive here
With 177+ marine species recorded in the area - including barracuda, bull sharks, dolphins, eagle rays and nurse sharks - Chankanaab Reef offers some of Cozumel's richest reef diving. Water ranges 27-30°C, warmest August, September, October.
Chankanaab Reef is one of those Cozumel sites we always suggest for a relaxed afternoon dive, particularly if you’re staying close to San Miguel. You won’t get the roaring current drifts here like Palancar or Columbia, which frankly, can be a welcome change. Instead, expect a gentler pace, letting you really comb over the smaller stuff. We love spotting the Yellowhead Jawfish, little heads poking from their burrows, sometimes with a clutch of eggs tumbling in their mouths. Keep an eye out for Sand Stargazers too, masters of disguise, buried in the sand with just their eyes peeking out, always good for a quiet chuckle. The reef itself is a mix of coral formations, with plenty of nooks and crannies. We’ve found some surprisingly large Marbled Morays tucked away, and the Candy Basslets are usually flitting about in the deeper sections, their colours really pop against the blue. Visibility is typically good here, often 20 metres plus, making it a comfortable dive for anyone who prefers to take their time and photograph the macro life. It’s not a site for big pelagics, but if you enjoy the smaller, often overlooked inhabitants of the reef, Chankanaab delivers.
