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 worthwhile. Although unfortunately there were no dolphins sighting, the trip was exhilarating and enjoyable. The guides and staff really made this experience very special, and I commend them for being such a group of people with great personalities. All locations were beautiful, and they truly did their utmost to try and locate the pink dolphins. I will be back, and I will try again with this tour group!

Reviews: Mr. Tu Fishing Day Trip by Escort Boat from Koh Samui
Guest User2024-09-12
It was a great day out on a boat fishing, Jo the deckhand was very helpful and cooked a fantastic yummy lunch! Lots of little fish caught, would be perfect for families with kids! The only downfall was out transport to and from the wharf with our driver going to 3 wrong hotels to pick people up and him picking up a hitch hiker on the way back, which I thought was a little bizarre! Overall a great day and would highly recommend.
