One of only 3 caves in the world. You must have a guide. Limit of people are allowed together inside. You can either buy your entrance ticket in the village below and also have pick-up car to take you up or buy at cave entrance. There are many posts in English to learn about the crystals formation. No pictures are allowed inside. Narrow stairs and go deep for 10 minutes. EXCELLENT.

The way to the caves is now quite easy to find, they have put up signs in English all the way to the ticket booth and car park. The entry fee is 80 baht per person which includes the 10 minute taxi ride to the caves (you are not allowed to drive yourself) and back to the car park. You are only allowed 20 minutes in the actual cave apparently due to lack of oxygen we did not have any problem and is self guided, don't expect it to be cool underground it's not and is very humid. Be aware when you have to clime the stairs back to the top the stairs are quite steep but you are rewarded with some great crystal formations.
