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

We had a very flexible and joyous 4-hour trip with our competent driver O! Thank you very much for your cautious driving and the informative chat about Thailand. We could arrange the time to our needs and take the time we wanted to stay to see the sights. A worth-taking experience!

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.
