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 tree bridge coffee ziplining - Tree Bridge Zipline
Guest User2026-09-06
I highly recommend it to anyone who hasn't tried it. I booked it as quickly as possible, and the next morning, at the appointed time, a company pickup truck arrived and took me to the base. They were a very friendly bunch. Thanks to these wonderful guys, it was fun and not at all scary. I want to thank everyone who was there and supported me ðŸĪ. I left my phone in the booth, so one of the wonderful guys took a video of the zipline flight for me on his phone and then sent it to me on WhatsApp. Free, no strings attached. He refused to take any money. I just took a big thank you ðŸĪ—. I definitely recommend having such a small and wonderful adventure on your vacation 😁

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.

Reviews: Departing from Koh Samui: Koh Madsum & Tean Island snorkeling experience | dolphin chasing tour upgrade available
Guest User2026-11-09
It was an absolutely fantastic experience on Koh Samui that you definitely shouldn't miss! Since we were there during the rainy season, the route had to be adjusted to the weather, which was handled perfectly. We simply spent a little more time on Pig Island than we did snorkeling. This gave us extra time to explore the beautiful island, in addition to feeding the pigs! We also went swimming... Afterwards, we went snorkeling and saw some cool fish. Because the weather suddenly turned bad, the return trip was quite an adventure! Luckily, nothing serious happened except that we got wet. You could tell the guides were used to the weather 😂 Overall, a truly amazing experience! I would definitely do it again!
