The pigs simply stole our hearts. We never would have thought we loved pigs so much. 😁. Definitely a must-see!

Reviews: 1-day tour to Mu Ko Ang Thong National Marine Park from Koh Samui [snorkeling/lunch/transfer/kayaking]
Guest User2026-09-08
The route matched the description. The excursion itself was wonderful. I highly recommend it. We were with the Funny Day team. They're great guys, but there was one major drawback I didn't like. On the way back from the archipelago to Koh Samui, we ran out of gas. Oh well, it happens. We first took some gas from a boat traveling alongside, but it wasn't enough. Then we waited for a second boat to bring gas and pick up some of the people. And it seemed like everything should go smoothly from there, but no! The new boat also ran out of gas 100 meters from the beach. And we waited for a third boat. They need to fix this urgently and bring extra gas. Otherwise, the excursion itself, the views, the snorkeling, and the kayaking were amazing. The views from the observation deck are incredibly beautiful, but the climb is very difficult and is best done in sneakers.

If you set it up before departure, you can use it immediately after arriving at your destination with just a few simple steps. After returning home, it automatically switched back to my original SIM, and the transition was smooth. The signal was good, and I was able to use it anywhere during my stay without any problems; I didn't experience any inconvenience. I would definitely use it again when traveling abroad!

The itinerary was fulfilling, and the scenery at each destination was breathtaking. The arrangements were well-planned, and there was great interaction with fellow travelers. The tour guide was also incredibly humorous and engaging, introducing many fascinating things. It was truly an eye-opening and worthwhile trip!

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 ฿50 pp entrance fee at Koh Mudsum.
