Reviews: Tean Island 1-day tour [Pink dolphin chasing available + Pig Island option]
Guest User2025-07-14
I apparently booked only the pig tour but wanted to book the one with the pink dolphins. It was not clearly written online and I therefore advise everyone to double check. Nonetheless, it was really fun and I was able to switch easily (but had to pay a small charge) for it.

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: Koh Samui 4X4 off-road island adventure tour: Hin Ta Hin Yai + Na Muang waterfall 1-day tour
Guest User2025-09-23
The 4X4 tour of Koh Samui was amazing! There weren't many Chinese people around, so it wasn't crowded. The guide was incredibly friendly, like a private guide. The wind blowing from the roof was truly breathtaking, and the experience of Sintha, Sinya, and Namuang Waterfall was truly captivating! This 4X4 tour of Koh Samui was an incredible experience! We barely encountered any other Chinese tourists the entire time, and there were no lines for attractions, making it a peaceful and relaxing experience. The guide stayed with us the entire time, attentive and caring like a personal guide. Not only did he proactively help us take photos of the wild scenery from the roof, but he also shared local anecdotes in Chinese and was incredibly welcoming to Chinese people. The pace of the tour was also very comfortable. We first visited Sintha and Sinya to see the pristine coastal scenery, enjoying the refreshing sea breeze. Then, we headed to Namuang Waterfall, where stepping into the cool stream was incredibly relaxing. The mountain roads were especially enjoyable, as I stood on the roof, holding onto the handrails, and the wind, wrapped in the fragrance of the trees, blew in my face. The sense of exhilaration was truly captivating. The entire trip was a perfect blend of excitement and relaxation!
