Reviews: 7-hour diving and snorkeling experience at Tean Island from Khanom [Koh Samui departure] Pink Dolphin Discovery 1-day tour by speedboat

Guest User2025-07-26

The tour guides and their energy made this trip worth it. Though unfortunately there was no dolphin sighting the trip was exhilarating and enjoyable. The guides and staff really made this experience very special and I commend them for that just a group of people with great personalities. All locations were beautiful and they really did their utmost to attempt to locate the pink dolphins, I will be back and I will try again with this tour group!
