Why dive here
With 177+ marine species recorded in the area - including barracuda, bull sharks, dolphins, eagle rays and nurse sharks - Chun Chacaaab Reef offers some of Cozumel's richest reef diving. Water ranges 27-30°C, warmest August, September, October.
Chun Chacaaab Reef is a site we always make time for in Cozumel, especially if we’re looking to escape the usual crowds further south. It’s got a genuine laid-back feel, a place where you can just drift and observe. We often spot the big parrotfish here, those impressive Dark Green Parrotfish with their striking colours, munching away at the coral. Look closely among the nooks and crannies and you’ll likely find a Caribbean Chestnut Moray peeking out, or the shy Candy Basslet darting into cover. What we really love about Chun Chacaaab is the sheer variety of smaller stuff. You'll see Eyed Flounder perfectly camouflaged on the sandy patches, and the intricate patterns of a Spotted Trunkfish are always a treat. Our favourite is watching the Yellowhead Wrasse diligently cleaning other fish, a mini drama playing out right in front of you. It’s a site that rewards a slow, observant dive. Come here for a relaxed pace, where the current is usually gentle, allowing you to really soak in the smaller details rather than just zipping past.
