We've never been in a cave, so we looked forward to this tour. They split you into two groups, one for Spanish-speaking tourists and the other for English-speaking tourists. We went in one huge cave that had many cool formations. It was awesome to see, so don't forget to bring your digital camera! Wear comfortable shoes, preferably sneakers, because it can be slippery. We highly recommend this trip if you've never taken a tour of a cave.
