  Great day - picked up from hotel to the cafe for drinks and a snack. Onto the boat and the island plus 4-5 more stops at bays for snorkelling. The snorkelling was a great experience but all due to the guides who got in the water and made sure we all saw the best bits. I missed the baby shark at first, so the guide swam with me and made sure I saw everything. They really made the trip exceptional. The lunch was lovely too and also the snacks later were also great. Fully recommend- those guides were brilliant and made our day. We also have some great photos taken by them and shared on a link after.

  We had an amazing day with Oxygen. We managed to see both shark, turtles and so many more fish. Beautiful corals. Both deep and shallow water. The tour guides were very friendly. There was coffee, tea, cookies and water always available. The guides took lots of nice pictures in the water for us. This was really an amazing tour.

  I booked the premium morning snorkeling tour as wanted to be with a smaller group and to avoid the big crowds. I think the extra money was well worth it. We went to five places including Nang Yuan island where you can do a short hike to the top of the island and / or swim and snorkel on the beach. Please note the entrance fee to the island (for all visitors) is an extra 250baht, but again well worth it for the money as it is beautiful. The other 4 spots were all for snorkeling from the boat. Our guides Aye and Win and the captain were incredibly friendly and professional and made sure everyone on board was safe and happy including the less confident swimmers and families with children. I also appreciate that Oxygen seem to genuinely care about protecting the ocean and marine life as this was important to me when booking the tour. The tour guides would swim with us and point out or take photos of things like the beautiful coral and amazing sea anemones, fish, clams and ocean life. We also saw a sea turtle which was very special... please note that you might not see turtles and sharks but you will see beautiful underwater worlds so there is no way you could be disappointed. Oh and we saw a puffer fish which was very cool! The photos they take are free and they are really good quality. Also there was a free lunch and tea / coffee / water available all day. The lunch was very tasty and the hotel pick up and drop off was well organized. Aye and Win were really great guides and made the trip enjoyable and special for everyone, they seem passionate about the ocean and the marine life. Thanks for a special and memorable trip 🙏

• Scammers

  I’m currently on this tour. Booked the more expensive tour to avoid scams. They make you pay for the gear to snorkel on the snorkel tour before you start. Leaves a very bad first impression.

  Fantastic day out on the water with a great guide. Service included pick up and transfers, full day boat trip around the island, multiple stops to snorkel in some great spots, and lunch on the boat. Our guide, Spy, was fun and informative, and our family loved the experience.

  What a fantastic excursion! They picked us up from our hotel and we boarded the perfect sized vessel. Our guide explained everything in great detail, including how to put on your snorkel mask for those who didn’t have experience. Each stop we made was gorgeous with superb snorkeling and a photographer took pictures both in and out of the water and made the photos available for download at no charge. I highly recommend this tour!

  Me and my two sons of 11 and 13 years old had the best day with the friendly Guys from Oxygen Tours. They took us with a small Group of fun people to the most beautiful bays of Koh Tao. We had the honor to Swim with turttles and baby Sharks. The service was fantastic at the boat and in the water. And also the food was very good. Afterwards we received a lot of cool pics they made with underwater cams. We made memories for life! Thank you Oxygen!

  Absolutely amazing day out with oxygen tours! Was very well organised from pickup to drop off. Our guides were excellent and took time to show us baby sharks and turtles. Took great photos and were very informative throughout the day. Food was also very yummy and had fresh water. Boat felt spacious for the small group and enjoyed jumping from the top deck. Would do this again in a heartbeat!
