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!
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!
