Reviews: Koh Samui Angthong National Marine Park one-day tour [Snorkeling/Lunch/Transfer/Kayaking]
Guest User2026-04-28
We really enjoyed the tour; everything went as planned. We were taken by speedboat to an island where we explored the marine life (corals and fish). Then we went to Angthong Island, where the observation deck offers stunning views. Our next stop was Koh Wuai Talap, a stunning island with a white-sand beach and an ideal spot for swimming.

Reviews: From Koh Samui: Day Tour Ang Thong with Kayak, Snorkel & Lunch
Guest User2026-05-19
Great tour! Of course, the weather has to cooperate, but rain on the open sea has its own special charm. In my case, it was 80% sun/clouds with minimal rain; the vibe on the speedboat was really cool and unforgettable.

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: Koh Samui: Hawk Adventure Ziplining Aerial Walkway in Nathon
Guest User2026-03-14
Exceeded all expectations! The views are absolutely stunning, but you definitely need to get the gold plan; the most beautiful flights are there. It rained from the moment we entered the slope until the very end, but the staff was always joking and smoothing things over, so the weather didn't ruin our day. Highly recommend.

Reviews: Koh Samui Departure: Mu Ko Ang Thong National Park Sightseeing and Snorkeling|Upgradable kayaking adventure
Guest User2026-05-18
Apart from the hotel pickup, which was over 45 minutes late, the excursion was fantastic. The crew on the boat was very friendly and accommodating. After the last stop at the island with the blue lagoon, we arrived in a heavy downpour and had to wait on the island for a while. The excellent team on the boat quickly secured all our belongings that were on deck – very thoughtful, but probably also a matter of experience, as they're used to the weather here. All in all, I can highly recommend the excursion.
