Our snorkelling trip in Koh Toa was amazing and it was made that way with the kindness and hospitality of our guides through Oxygen Tours. Can’t thank them enough!

Very nice tour and friendly staff and the boat is not unloaded. We were able to tick off the list nicely turtle some baby sharks and lots of beautiful fish.

Great experience!we would have loved to see sharks and turtles but it wasn’t to be- couldn’t be disappointed with the reef and enjoyed the food.

Very mixed feelings about this trip... the crew were lovely and it seemed pretty well organised r.e. counting everyone back onto the boat, the food was food, transfers were easy. However, I do think that too many people in each spot on each day is creating a really sad set of coral reefs. Despite our guide telling people not to touch or stand on coral, so many people did and 0 consequences. I also think that we came in rainy season... it must be ridiculously busy during the high season. We saw a really wide range of fish and a turtle but it was sad to see the fish trying to feed from dead corals and to watch 20+ people crowding one turtle so they could get their picture. The poor turtle was just harassed the entire time with people around it and following it while it too, tried to feed from limited pickings. Shark Bay where we saw it, looked like a bone graveyard 😞 I wish people were more respectful of the nature we are so lucky to have.

We had a brilliant day out on Chuan Chom with Oxygen Tour. From start to finish, the service was excellent – the staff and guides were so friendly, professional, and knowledgeable. We were lucky enough to see turtles, barracudas, and countless beautiful fish. Every snorkeling spot was stunning, and the whole trip felt really well-organised. The food was delicious and plentiful, and everything ran so smoothly that all we had to do was relax and enjoy the experience. If we ever come back to Koh Tao, we would definitely go again without hesitation. Highly recommend this tour to anyone wanting a fantastic day on the water!

The tour was absolutely spectacular and perfectly organized. The guides were incredibly friendly, especially Nut, who guided us in the water, showing us different types of fish, corals, and marine life. They were very approachable and made the whole trip even more enjoyable. The food was delicious, and the free taxi service to the hotel added great convenience. The spots we visited were stunning, and we really appreciated how the guides emphasized preserving marine life—avoiding stepping on corals and never touching the turtle at the last stop. Truly a wonderful experience. Highly recommended!

We did the PREMIUM trip. I was a great experience for my family and I. The boat was perfect, we were around 20/25 passengers/customers on it. The staff was really really nice, and pay intention to us all the time (in the water, on the boat). I definitely recommend this company, and the PREMIUM trip.
