Guides such as Phillips and Phill are known for helping guests spot dolphins and taking photos. Expect seven hours, changing sea conditions, and a THB 50 adult fee at Koh Madsum.

“Pig island was lovely, and great to be able to swim and chill for an hour.. snorkelling was average as the sea wasn’t very clean and the dolphins were cool once you got to see them.. I don’t know if I would bother searching for the dolphins again and just go for the half day trip without them would say it was fully worth the money for all of it.”
