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!

I booked this eSIM when I was stuck at Bangkok airport after my flight got cancelled. It was an easy and very convenient way to have constant, fast and stable internet access during my extended time in Thailand. Easy to install and even easier to use.

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 😁

Reviews: MuayThai Class for Beginners
Guest User2026-02-19
I went to a Muay Thai for Beginners class and absolutely loved it. The instructors were very professional and clearly took their job seriously. We started with a proper warm-up and stretching, and we also finished the session with stretching. There were always 2–3 trainers coming around to check on us and give individual guidance. I think Muay Thai is definitely a must-do activity when you come to Thailand. Since it’s the national sport, practicing it here also allows you to experience and understand Thai culture from the inside.

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.
