The trip was wonderful! Phillips is a very nice guide, he was definitely setting up the positive attitude for the whole trip, the trip itself was good, we had enough time at each location, and the food afterwards was so delicious!  Thank you!
Reviews: Koh Samui Pig Island and Tean Island Snorkeling with Pink Dolphin Half-Day Tour
Guest User2025-10-22
The half-day trip was very relaxing, and I didn't have to get up early. Maybe everyone doesn't like half-day trips, but it was just my daughter, another couple, and me that day, so it was a very relaxing experience. Pig Island is perfect for children. While there's nothing particularly exciting, the kids loved the pigs. We even rode a jet ski (optional) and snorkeled once, which was a very relaxing experience. The weather was nice, and the sunset was beautiful. The departure pier was a bit far, and it felt like almost an hour's drive. The boat was quite fast, arriving in less than half an hour.

Reviews: Samui Island, Ko Tao + Nang Yuan Island one-day tour [Koh Tao | Chinese/English guide | hotel transfer]

This starry sky LM speedboat Koh Tao Nanyuan Island day trip experience is really very good, the speedboat is not crowded, people sit very loose. David tour guide and another staff member are particularly good, explain in detail, and very warm and cheerful, also helped us take pictures underwater! The next day I met them in the Antong Islands and felt very kind. Snorkeling on Koh Tao is beautiful, you can see a lot of fish, Nanyuan Island is a bit glass sea, when we go, it is cloudy, it is also beautiful, the sunny day should be more beautiful.
