Scuba Dive Cozumel with Aldora Divers

Welcome to Aldora Divers, Cozumel's premier scuba dive shop!

Since 1995, we've been providing unparalleled diving experiences, with a focus on personalized service and exceptional customer care. We're proud to offer longer dives with our high-capacity steel tanks, which provide 50% more air and allow for extended bottom times of over 70 minutes per tank. Our computer-aided multi-level dives ensure maximum safety and enjoyment for our divers.

At Aldora Divers, we understand the importance of tailored experiences, which is why we only allow six divers per boat and group them according to matched experience level, similar underwater interests, and gas consumption. This ensures that our divers have the best possible experience, whether they're novices or seasoned pros.

Our restricted group sizes also allow our expert guides to take our divers to all sites on the island, including those in the far south, north, and east of Cozumel. This means you get to experience the full range of Cozumel's beautiful and diverse reefs.

We're proud to offer these exceptional services at no extra charge, as we believe in keeping experienced and novice divers separated across our fleet of eight boats. So come dive with us at Aldora Divers and experience the best scuba diving that Cozumel has to offer!

Windward Diving

When the port is closed due to a 'Norte' and when the weather permits, we move our entire operation to the east side of the island to make sure our customers can get a chance to dive.


Aldora is the only diving facility that provides organized and safe diving on the Eastern side of the island.
