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

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!

Easy to use, eSim loads directly from Trip.com app, switch on phone at destination, and good to go. Better signal than back home!

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: 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 🤝. 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 🤗. I definitely recommend having such a small and wonderful adventure on your vacation 😁
