While the caverns are incredibly beautiful, our tour was disappointing because the group was too large(over 40 people), and a family of foreign tourists with children and babies were very disruptive. They did not speak English, and most likely didn’t understand English either. They spoke very loudly, and were busy trying to calm crying children while the tour guide was explaining the features of the different formations. The group after ours consisted of about 20 people. When my friend and I told the management that our group was too large and loud to hear anything they just said that they knew that, and we could go through the caverns again if we wanted. We suggested that they cut off the group at 20 – 25 people. If you go, make sure your group is small. It’s a really beautiful place, but I still don’t know much about the history or significance of some of the highlights in the cavern.
