Reviews: Koh Samui vintage red sailing boat sunset tour with pickup service and buffet
Guest User2025-01-19
The time is not long, it feels right, there are not many people, a total of 11 tourists in a boat, the sea fishing, and jumping from the boat to the sea. Eat and drink, and give an ice cream for one person after dinner. Adults and children play very well, that is, the weather is not good, cloudy, no sunset

Reviews: Koh Samui one-day tour[Off-road Vehicle Around the Island | Island Sightseeing | Optional Elephant Encounter or Kayaking]
Guest User2025-02-20
As a Chinese, this is to come to Samui again after the epidemic. I have traveled here for three consecutive years in 16, 17, and 18 years. At that time, there were still many Chinese tourists. I just want to say that the island tour is still very happy. My wife also thinks that the tour guide and SUV experience is great. At noon, we have dinner with foreign friends and dance! Unforgettable memories, I hope that there will be more Chinese people to play, although there are many small hotels that can travel around the island or sea at the entrance of the hotel, I suggest to customize directly from Trip.com (safe and secure, and Chinese communication), the next day the hotel lobby is just waiting...! In short, Thailand is safe, you can come and enjoy the beautiful scenery here if you have the opportunity

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: Koh Samui: Koh Tao and Ko Tao + Nang Yuan Island 1-day tour speedboat snorkeling with hotel transfer and lunch included
Guest User2026-02-05
It was a decent tour, but its main drawback was probably the price; I wish it were cheaper. We were picked up from the hotel on time, then driven around half the island to pick up the others—the Chinese are very unpunctual, and we had to wait a long time. We were taken to the pier, given water and buns, and loaded onto a speedboat for about 30 people. The ride to the first spot took about an hour and a half. Along the way, they offered free water and soda, and also sold beer and swim shoes. The place is very beautiful; I even saw a turtle! But there was a lot of trash in the water... Then we were taken to the second spot, and then to lunch. The lunch was meager, but oh well, we didn't go there to eat. After that, they dropped us off at a beautiful beach for a couple of hours, but be careful—the sun is very strong. The ride back also took about an hour and a half, plus transfer to the hotel. Overall, I can recommend it!

Reviews: Koh Samui Angthong National Marine Park one-day tour [Snorkeling/Lunch/Transfer/Kayaking]
Guest User2026-01-31
It was an amazing tour. The schedule was very full and well-organized. For just a little over 1,500 baht per person, it was definitely worth the price. The package included a boat ride, snorkeling to see fish and coral, and a photo service with very good staff. We also got to go up the mountain to enjoy views at two different spots. The food was delicious and served in generous portions. Overall, it was a very packed and great-value program for the price.
