Our 2nd day was superb!

The cenotes are unbelievable! In the middle of the jungle, you suddenly come upon a huge hole in a ground and then discover a crystal-clear lake inside.

Cenote Ponderosa: We found red-eared sliders (Trachemys scripta elegans), 2 species of cichlid and courting sailfin mollies (Poecilia velifera) in the water. It makes you feel like you're in an aquarium. Under the lakes, you find the world's largest cave systems, parts of which are suited for diving.

My boss, Roland Böhme, was excited and anxious at the same time about this part of the expedition. Diving deep in caves where you don't see any light when you switch off your dive light and can only find your away back to the exit by following a guideline takes some getting used to. But we were generously rewarded with crystal clear water - which, by the way, was anything but warm - and fantastic caves. Wow, what an amazing experience!

You might like to watch the movie, Sanctum, which lets you experience what diving in caves feels like on a TV screen. Michael Gruss was barely able to tear himself away from the fish. A fan of livebearing killifish, he was completely in his element in the cenotes. Soon, we'll be returning to the Playa del Carmen beach, dinner and time to look back on a superb day.

The weather at 3:00 PM: Sunny, slightly cloudy. Air temperature: 28.4 °C
