I would have given this place a 5 star review but they were doing constriction and there were no signs at the ticket counter letting you know they were in a building across the street. Also they give their last tour at 4p and I was unaware and came slightly after. However they still took me down. My guide was very knowledgeable and was actually a studying geologist. I do feel like the tour was a bit rushed and quick compared to other cave tours ive been on but I understand I came at the last minute. Also I could see a majority of the people visting this cave were doing excursion tours. The walking tour is only a small park of the cave where as the excursion tours explore more areas of the cave. The age limit for excursions is 6 and I would definitely come back and do it when my son is a bit older. Overall it was a great knowledgeable experience and we will come back!
