We snorkeled with Chris at Hidden Worlds during our fabulous Yucatan vacation in March of 2005. It was by far the best experience of our vacation. Chris is a very experienced cave diver but he took his time with us novice snorkelers to explain the history, geology, ecology, flora and fauna on the cenote and the surrounding area. Chris also recommended several other cenotes and lagoons for us to snorkel the rest of the week. Whether you are a serious diver or a beginning snorkeler you need to visit with Chris!
