It is a very interesting tourist attraction and definitely worth taking a chance here in your lifetime... it is adrenaline-filled and I really like the abundance of plants and animals in this cave. It is great to see bats hanging upside down to sleep. It did enrich my knowledge. On your arduous island journey, you will clearly see hundreds of bats hanging up and down from trees at the edge of the hole. It was a cool scene. The water here was great. We dive nearby. No doubt it's worth a look.
