Reviews: Depart from Koh Samui: Private Charter Boat Tour [Snorkeling + Island Hopping]|Longtail Boat (Optional)|Speedboating, etc.
Guest User2026-10-15
Private longtail trip to Koh Mudsum (Pig Island) and Koh Tan with our two boys. Boat and driver were great: kind, careful and on time, and the weather cleared up nicely. Good value for a private boat. One thing to improve: we had no explanation of what was on each island or what to expect, so a short briefing at the start would make it even better. Bring cash for the āļŋ50 pp entrance fee at Koh Mudsum.

Reviews: Koh Samui: Private Longtail Boat to Pig Island with Snorkel
Guest User2026-07-27
We have nothing negative to report, even though the island is relatively crowded. The children were delighted and had a great time. Departure from Koh Samui, pick-up from Koh Madsum, and the snorkeling trip went perfectly and as agreed. Our "captain" was very friendly, reliable, and punctual. We would definitely book through this company again 👍🏞

Reviews: Private half-day longtail boat tour to Koh Mat Sum from Koh Samui
Guest User2024-04-03
The only downside was that we were picked up half an hour late. Otherwise, it was great. We had the boat to ourselves (3 people).

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: Koh Samui Pig Island and Tean Island Snorkeling with Pink Dolphin Half-Day Tour
Guest User2026-07-29
We booked this trip as one of our favourites. We were picked up on time by a friendly driver in an air conditioned mini van. We were driven to the pier and had time for a coffee. The driver was super friendly and professional. We were on a speedboat which was exceptional fun. It took 15 mins to get to tean island where we snorkelled. They provided water, snorkels and the health and safety was also exceptional. Snorkelled for 45 mins and then took a 5 mins spin to pig island ! This was absolutely amazing. The place was full of small, medium and large pigs. They were lovely. You can feed them and let them drink from a bottle. We had a lovely lunch (vegetarian and meat options). There is a bar there also. We had time to swim and chill. It took 15 mins back to the pier where our driver was waiting for us and then returned back to the hotel. One of the very best organised trips I've ever been on.
