Cozumel was the best stop of our trip. Absolutely gorgeous. The water was so clean and blue that even from the ship in relatively deep waters, we could still see through to the bottom.
We took a tour inland to the Mayan ruins at San Gervasio. The temples and shrines here date back to 300 AD, and this was once a place of worship of the goddess Ix Chel, deity of the moon, childbirth, fertility, medicine, and weaving. Our guide said Mayan women would visit San Gervasio if they were having issues with fertility.
Also prevelant in San Gervasio were iguanas. More like miniature dragons! We saw many of them, and some were nice enough to pose for photos. I thought they were pretty incredible.
