Tulum was one of the most highly recommended places in Mexico owing to its white sand beaches and picturesque oceanside ruins. I enjoyed both as well, although they each had their own negatives too. The beach was great for an afternoon swim, but unfortunately was overrun with seaweed during my time there, which clouded its typically turquoise color. The ruins were beautiful, but by 11 am they were brutally hot and overcrowded with tour groups.
My real highlight of Tulum was the cenotes. There are plenty of these natural sinkholes around the peninsula, but Tulum was the only place I went diving in them. The first day Karim and I snorkeled in one and discovered the appeal of its crystal clear water and fascinating cavern formation. We also saw how much more the divers were able to explore. So we checked out a couple of dive shops in town and decided to go for it when we found one that would let me dive in two too (Karim is advanced certified but I am not certified, so finding one that would let me do two cenote dives was tough since technically it’s not allowed).
We started in Casa Cenote, where they take all introductory and refresher divers since it’s always possible to surface in case anything goes wrong. We barely got any lessons before the dive started, something that was fine for me having done this a couple of times already but surprising given how Discover Scuba dives are supposed to go. The point of this dive was to test our buoyancy control; cavern diving requires a much more controlled, even dive style than open water does because there are rock formations above, next to, and below us. The first moment we went into a cavern I had to check myself mentally. “Oh right,” I thought, “this is what we’re doing, diving in a cave, with solid rock around me.” Luckily my next thought was, “This is so freaking cool!”
Our guide judged that we all did well enough on our first dive so he took us to Gran Cenote. This time we would really be in the caverns. Air was never too far away, but most of the dive we were surrounded by stalactites and stalagmites and frequently had to use flashlights to light the way. It was awesome. There’s something so uniquely cool about exploring caves in water. It’s another world down there. It’s not about reefs and wildlife like open water diving is, it’s about natural architecture under the earth’s surface. When we got back on land we were all stoked about what we’d just done, and I personally vowed to return once I’m certified to do more dives like this.
The next day Karim dove in El Pit, a huge deep cenote where advanced and cave certified divers can go down to 40 meters. Visibility is 100 meters and light rays that penetrate the water looked like something out of a sci-fi movie. One day I will go back and do this.
