Reviews: Koh Samui Jungle Elephant Sanctuary Half Day Tour
Guest User2025-11-21
Wow what an amazing day! The pick up was on time and hassle free direct from my hotel. It had been raining so I think that meant a few cancellations, all the better for me who ended up in a small group of just 5. John was our guide. A lovely intro with a nice coffee. Then we got to meet and feed some gorgeous elephants. And a great photo opportunity . We then went to meet the rest. (They have 7 at this sanctuary). Plenty chance to ask questions and know everything about their elephants. A quick coffee then change for a chance to shower and brush the elephant. This was fantastic! What a wholesome , amazing day ! I definately recommend you visit when in samui

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 Angthong National Marine Park one-day tour [Snorkeling/Lunch/Transfer/Kayaking]

It was a good option to see the offshore islands if you have extra time in Koh Samui. It was fun but expect the lunch to be very simple.
Reviews: Koh Samui Departure: Pig Island & Tean Island Snorkeling Experience|Upgrade to a pink dolphin encounter
Guest User2025-12-22
An excellent excursion. I really liked the guide who explained safety rules with humor and accessibility. The boat is modern, and the equipment is in good condition. We didn't use masks; we brought our own. Snorkeling near the island was fine if you don't expect anything special: there are live corals and cute fish. The pigs on the island roam freely, approaching tourists without fear, and happily enjoying the food offered. Despite the abundance of animals (pigs and dogs), the beach is clean; it's clear the staff cares for the island. Drinks, snacks, and food for the pigs are available at the bar. Overall, the experience was excellent!
