It was an amazing day! We had a great time and saw many turtles, baby shark, fish and corals!! The Mood of the boat was very good and the guides did great, especially Tai who was with us all the time and taught us a lot! Very good food too!

I recommend everyone who visits Ko Tao to do this tour, The view of the coral reef is breathtaking, also you have the chance to see turtles and sharks among the most beautiful beaches of Ko Tao. Lunch and snack are included in the price, along with snorkeling equipment and in addition to this at the end of the excursion you have the opportunity to buy a saucer with photos taken during the day. Thank you so much for this experience!

I had an amazing experience. They had a nice little bit smaller boat then other company’s so the travelling between the different snorkelling spots was really relaxing. Nice food, nice people. Free pictures that can get taken of you with their go pro (see the added pictures) :)

Very kind staff and very good photographer: he always swam with us suggesting where to see an old and large turtle, a small shark (not dangerous) and many colorful fish. Beautiful and unforgettable experience for the whole family!

A day to enjoy fish, small sharks and sea turtles. For the price, 22 euros per person, not bad at all. They picked us up at the hotel, left you the glasses and the dive tube, fed you (rice, with minced meat and lettuce). We stayed from ten in the morning until five in the afternoon. The crew is friendly and makes the day very enjoyable. Recommended for the whole family.

Initially communication was good with the tour operator but it all fell apart on the day- we had a call to wait at our reception the driver will be with us in a minute- 15 mins later they arrived. We found that there were so many tourists on nang yuan island that it was actually unpleasant- 40 min queue to get to the ‘viewpoint’. The rest of the stops you could get to be hiring a scooter and then you might actually be able to enjoy the stops and see something. The quality of the snorkels was poor- all four of our group had issues with water in the masks and snorkel leaking. Food was good for lunch and staff were friendly. I don’t know why but after the last stop we didn’t return to port as planned we had to get a long tail boat to shore and taxis from there- meaning we were an hour later than planned, no explanation from the team why this had occurred and the organisation of people onto boat/taxi was pretty chaotic. Overall not really worth it, wish I’d got a scooter and a snorkel instead

Amazing! Repetitive ES see how all the commentators EN always described the tour as "it has been the best tour I have done in Thailand" , because in this case I agree 💯 %! It's DE ten! The horny monitors, making jokes and with a great sense of humor all day, have taught us the best places to find fish, turtles and baby sharks! NO photos have been taken under the sea, the food has been excellent and of course, the views stunning! Thank POR an amazing day! Great experience🤙 Keep it up!
