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.

Reviews: Half-day ziplining tour at hawk adventure in Ko Samui
Guest User2026-08-20
My 13-year-old daughter went. She really enjoyed it, although she wasn't expecting much. We thought there would be more of an obstacle course, but it was mostly ziplines. It felt a bit lacking in extreme sports. She said the views were amazing. We took the gold package.

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: From Koh Samui: Day Tour Ang Thong with Kayak, Snorkel & Lunch
Guest User2026-08-20
🌴 Excellent island tour – highly recommended! I really enjoyed the organization of the tour! From the very beginning, we were fed sandwiches with jam and had unlimited drinks. Water was constantly provided throughout the trip – there was enough for everyone. The lunch was also great: watermelon and Thai dishes. We had plenty of time at each location: we snorkeled peacefully with the fish and admired the corals, and on the island, we even managed to climb to the observation deck. I'd especially like to highlight the attentiveness of the guides: during the ascent and descent, they stood along the route and offered water. The guide constantly offered to take photos, and my parents even took a romantic video. ❤️ I rate the work of the guide and the entire team 100/10! Everything was organized comfortably, attentively, and with care for the tourists. Take the tour – you definitely won't regret it! 🌴🐠
