We visited on a rainy day. It's a very "live" cave, and one corridor was flooded, so we weren't able to see it for safety reasons. The tour lasted just under 35 minutes, and was worth the $20 (cash only) entrance fee per adult ($10...More

First of all, bring cash, not credit or debit cards, because the owner will rudely tell you that he has it posted on his website 900 TIMES (!!!!) that he only takes cash. Luckily, someone in our party had enough to cover the $80 bill...More
