The SCUBA diving experts at the Professional Association of Diving Instructors have opened me up to the many adventures in their sport. Encountering underwater wildlife and examining shipwrecks could definitely lure someone into SCUBA diving.
But I started thinking about some of the reasons I like hiking; one of the main reasons I hike is to see cool geological sites. Volcanoes, towering cliffs, caves, that sort of thing. I asked my PADI friends what sort of geological oddities I could find underwater.
The PADI crew tells me the cenotes – or sinkholes – in Mexico might be the best bet. There are cenotes all around the world, from Australia to Canada to Zimbabwe. The famous The Great Blue Hole dive site in Belize is one example.
But let’s talk about the cenote dive sites in Mexico’s Yucatan Peninsula. They’re packed with stalagmites and stalactites, two of the features I like best in dry-land caves. These are some incredible caves. It sounds like you have thousands to pick from in the Yucatan thanks to a lot of limestone. You can narrow the search for a great cenote dive site by consulting a PADI dive centers near Playa del Carmen: Pro Dive Mexico, Scuba Playa and Dressel Divers can all help you find a great cenote dive site. If you really want a long-lasting adventure, find out which ones connect to larger, horizontal underwater cave systems (some cenotes are connected, and can extend 300 feet under the water table).
Something else cool about cenotes in Mexico: They have their place in the mythology of indigenous people. In the Maya culture, some cenotes like the Sacred Cenote of Chichen Itza were considered a gateway to the afterlife. So you may catch a glimpse of artifacts or human remains!
I’m still on a quest for more interesting underwater geological sites. I imagine that any underwater volcanic activity is probably too deep and otherwise dangerous for SCUBA divers to approach (but correct me if I’m wrong). And I’d love to know of submerged meteor impact craters, fissures -- just about anything. Chime in with anything you know about, and I’ll collect your info for a future post! In the meantime, here’s a fun blog post about cenotes in the Yucatan. It also has some good photos.
Thanks as always to my friends at PADI for the great information.
