"The activity was one of the highlights of our whole trip in Thailand! I would highly recommend trying it if you are like me and have no experience. The safety and basic training is completed thoroughly in the office before you start and then in shallow waters before you dive. The staff and our instructor were very friendly and our instructor was so patient when teaching us. You have the option after the first try dive whether or not you would like to do another dive and I would recommend you do because you begin to relax more and enjoy it more. We loved it so much we are looking for other places we can scuba dive because we are dying to do it again!"
