Reviews: From Koh Samui: Day Tour Ang Thong with Kayak, Snorkel & Lunch
Guest User2026-04-13
The trip was fantastic!!! The transfer picked us up and dropped us off at the hotel. We had breakfast and lunch during the trip! It was a challenge to get to the top, but it was definitely worth it. We tried kayaking—I loved it—and also snorkeled to explore the underwater world! The team—the guide and captain—were all very attentive and thoughtful, thank you so much!★

Reviews: Day Trip to Koh Nangyuan & Koh Tao by Insea Speedboat from Koh Samui
Guest User2024-08-17
The trip to Koh Tao and Koh Nangyuan was possibly the highlight of our stay. The snorkelling was amazing. We didn’t see the turtles unfortunately but the views were breathtaking. I personally felt Insea as a company was a bit harsh and nothing was explained at first. The lady on our boat was lovely. The speedboat was hugely uncomfortable for me…not brocade of the bouncing but the slant at which you’re sitting for 90mins…it’s not good for your back. The food was delicious!★

Reviews: From Koh Pha Ngan: Day Tour Ang Thong with Kayak, Snorkel & Lunch
Guest User2026-02-06
Comfortable. They picked us up from the hotel, fed us, and gave us Coke, Fanta, and water during the trip. Everything was great. Cons: They didn't contact us to tell us the pickup time, and they didn't mention that we'd have to pay 300 baht for a national park ticket when we checked in at the pier. Otherwise, everything was great; I liked it.★
