The Long Tail ride was of course super good. When snorkeling, the water was unfortunately too cloudy, which unfortunately cannot be influenced beforehand. We had imagined the island of Koh Madsum differently. There wasn't really much to see there. The organization itself was perfect. Our guide was very accommodating with everything.

The guide was very punctual, arrived our hotel 20 mins before 8am which was very impressive as some guides/agencies don't keep time that well. He was also friendly and helpful, taking many photos of our family. The tour included drinks but not food. The tour time (around 4-5 hours) was perfect for our family especially for my old parents, who can't do longer boat trips. Overall it was the best value compared to price. Thank you!
