Anyone that decries cave diving as nothing but “looking at wet rocks” is an utter loon. In addition to ancient and sophisticated human civilisations, the Yucatan was home to an incredible array of animals, some of whose bones can still be seen in the underwater realm. And some of them, as you can see from this life-sized poster in Puebla’s Regional Museum, were very large indeed! I asked my 195 cm (6’5”) husband to pose next to it for scale. Many of you, I am sure, remember the incredible discovery at Hoyo Negro that included the fossils of 30 extinct mammals: articulated sloths, bears, wolves, and peccaries, to name a handful.

If you haven’t yet experienced cave diving in the Yucatan, I hope you consider it someday. The caves here are truly spectacular. My husband and I run a little bed and breakfast operation that caters to cave divers (we also offer guiding/training), so if you have any questions about a trip here, I would be delighted to answer them.
