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!

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!

Reviews: Samui Boat Charter, Private Speedboat Charter, Angthong National Marine Park

Guest User2025-12-24

The boat was well equipped and maintained. Hong, our guide, was wonderful and super engaging and playful with the younger kids in our family. Nut and Film - our other crew members - were equally attentive and friendly. Overall we had a fantastic and well executed day! It started with picking us up at the beachfront of our hotel, then to the Angthong Marine Park (we visited first to avoid the large crowds so that the climb up and down to the Emerald Lagoon wasn’t rushed for our little hikers), then to a spot north of the park to privately snorkel, followed by lunch (we preordered so that the food was ready for us when we arrived), next to a private beach cove (which unfortunately was covered with plastic rubbish but our team quickly cleaned the beach with help from us) and then back to the beachfront of our hotel in Bophut. The experience was fully enjoyed by all in our family, from the youngest to the oldest. I highly recommend this company - booking was a breeze and communication up to our tour and throughout our experience was impeccable.
