I have not personally experienced this as of yet, so I don't have much to write about this. I also don't have very good photographs to present. I however wanted to at least put this page up so that visitors to Koh Larn would be aware that this activity is available.

What I do know is that this is used for tourist to view coral reefs and marine life. Inside below the water level it is air conditioned with seating facing the view ports. Sorry I don't know who to contact or where to board this vessel. If someone has more info please contact me.
