Mixed experience. Good except… - Good value for money. The crew gave clear direction about meeting times and activities. For example walk up to the view point first because it does get busy and queues form quickly. Lunch was plentiful, plenty of cold water to drink. In comparison to other snorkelling trips I have experienced this tour could improve its information as to what you can see. Their suggestions were a bit random, “you may see this here,” “ over there you may see that”. There was a lack of support to describe what the smaller fish and other things you could see. At one point they suggested we follow the guide to see something amazing, but the guide had set off before the majority of the customers had got into the water. As regards the turtle spotting, the experience could be regarded as very unethical. We received via WhatsApp hundreds of photos of people swimming unacceptably close to the lovely creature. It must have felt hounded by humans. Some wanting their perfect photo moment despite the cost to the turtle. I honestly wished they hadn’t pointed out where the turtle was. Hundreds of photos of people snorkelling deep. We had enjoyed the trip, till we got home and received the photos.

Not ecofriendly - I thought i booked an ecotour, but this tour was not ecofriendly at all. The guide and all the tourtist snorkeled almost next to the turtles just to take nice pictures, not keeping proper distance. The boat had loud music on which is bad for sealife. And everybody had plastic bottles with them while i thought it wasnt allowed. Many sunscreens are bad for the coral and this wasnt explained nor was the sunscreen checked. The coral around koh tao is mostly dead (i was here 20 years ago when it was still alive) and these kind of tours make them die. This tour is just a nice sightseeing tour. Everybody was very kind and helpful so i hope this feedback will make them change in the future.
