A fantastic experience sailing in the most beautiful bays of Koh Tao and snorkeling, with the Guide and explanations of the crew members, discovering the marine fauna of the coral reef and meeting the sea turtles! There was also a visit to the picturesque island of Koh Nang Yuan and the boat trip was pleasant and comfortable and kind and helpful all crew members. Hearty and tasty lunch buffet. Absolutely highly recommended!

I recently went on a day snorkelling trip with Oxygen. The trip I choose was the Premium which covered five different locations during the day which was brilliant! From the off, I was impressed with how friendly and professional the staff were. We were all offered tea and coffee first thing while on the way to our first location. The while day was structured and well organised which made me feel reassured. We stopped off at our first snorkelling site which was stunning! We saw lots of beautiful fish and fillers the guide who was always finding lots of different fish. We then went to a stunning island and stopped off at a view point and got some great pictures. As a sole traveller, the staff were great and helped take some pictures. We then had some really nice food and enjoyed the four other locations throughout the day. I couldn’t recommend this trip and company enough! I was lucky enough to do this excursion on my birthday which made it extra social. Thanks to all the staff once again for the day and looking after my luggage while on the trip.

One of the best snorkelling trips I’ve ever done. The staff were the best. Don was fantastic! So cheerful, friendly and made everyone so happy! The food was included and was also very nice. Coffee, tea and water were unlimited. For 5 stops, it was so worth it. I would definitely recommend to do in Koh Tao. 500 bahts is nothing!!!

I am a former diving instructor on Koh Tao. My daughter is 9 and not old enough for scuba diving, so we went snorkeling with Oxygen. It is a super professional and safe operation with stops at alle the best snorkeling sites in the island. The crew is super nice and friendly and went out of their way to ensure a great experience. Example: When we did not see the large turtles in Shark Bay one of them towed my daughter 300 meters with high speed free diving fins till they found a turtle. On return to the boat he found 2 more turtles and back on deck it was high fives and hugs from the dive crew. The locals here love children so don’t expect this level of attention as an adult but they are really nice. It doesn’t get better than this!
