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!

We took a boat for just us ... we left early ... sea was flat on the way out . Great captain and mate and "guide". Going out early you might snag a "private" beach which can be yours until you leave ... very safe boat ... wind up in the afternoon but great boat in a little choppy sea on run home. Could not fault the day

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.

Reviews: Snorkeling & Island Hopping

Guest User2025-08-09

Our crew could not have done enough for us on this trip. They were friendly, helpful, hardworking and polite. We had a great time swimming in the turquoise sea, away from the crowds, snorkelling above the coral reef and meeting the pigs before having a secluded picnic on the beach. What more could you ask for. Thank you!
