Absolute highlight - An absolute highlight of our Thailand trip! The guides were so nice and made us laugh all the time. We have seen many baby sharks, sea turtles, corals and colorful fish. The food was also very delicious. The snorkeling tour was incredibly fun and I can only recommend it to anyone!

The best Snorkling trip and the nicest crew - We had the best day so far of Koh Tao doing the full day Snorkling tour. The transfer was perfectly on time and took us to the pier where we got on a spacious boat will lots of room to sit and chill out between Snorkling. All of the crew were lovely, helping us in and out of the water and guiding us to see a reef shark and turtle. Would 100% recommend this tour is you’re looking to do a Snorkling trip in Koh Tao :)

Wonderful experience! - Amazing experience! I was impressed by how professional the crew was and also by how well the communication was. They called me via WhatsApp to let me know my ride arrived to drive me to the boat. The team was very friendly. The sights were beautiful and the lunch provided was delicious! They also give you all the photos from your snorkel trip for free which is a nice little perk. Highly recommend!

Unforgettable day in the coral reef 🪸 🐠 - 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!

Amazing - 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) :)

Beautiful pictures, wonderful! - 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!

Lovely snorkeling trip - Nice snorkeling tour which I would highly recommend. We come by boat around to five cozy coves and islands. Beautiful snorkeling sites with lots of fish. There are also many corals, but I think unfortunately many are bleached. We saw two large sea turtles, great experience. Nice food aboard the boat for lunch.
