Great day, the team is very dynamic, cheerful, efficient, humorous. They offer us free services such as photographs of participants underwater which is very exhausting to do for the photographer. The meal was very hearty, diverse, with fresh pineapple and cupcakes for dessert. We discovered many beautiful coves, anemones, multicolored fish and turtles with a very thoughtful and erudite guide.

This was a fantastic experience. We were so lucky to see a number of different things including a barracuda and a turtle. Snorkelling fantastic. Nang Yuan Island is beautiful - but there is a queue to get to the viewpoint. The view is fantastic. Staff brilliant. Food delicious. Nice calm with lots of space on the boat. Would highly recommend

First, I’ll say this company has it DIALED. They pick you up at your hotel and take you directly to the ferry. They manage large groups with expertise, making sure everyone is accounted for and safely back on the boat every stop. They share safety and conservation information and you can tell they really love their country and the jobs they do. All guides worked incredibly hard and were so friendly and jovial. They go above and beyond what you’d expect for the price you pay. One guest sprained his ankle on the boat somehow and they accompanied him to the hospital and made sure he was given proper care and provided translation on his behalf. After the tour, the company then drops you off at your hotel front door. We were so impressed with our guides and the entire tour.

This one was so special. The crew made us feel welcome and always looked out for us. The snorkeld with us, showed us turtles and sharks and explained about all the fish and different kind of coral. The took beautiful underwater pictures of us and of the sea life. They send them to you a day later. Food was good too and the snorkeling itself was the best on Thailand. Very highly recommended? Thank you!

Fantastic trip on a large and spacious boat with few people. It was quite windy the day we left, so we didn't get to go to Nang Yuan or stop at all the places we were supposed to, but we appreciated that they didn't put us in danger and instead let us snorkel longer in the places that were safe. The crew was good at making sure everyone was there along the way when we swam around to snorkel. They showed us good snorkeling spots where we saw several turtles, among other things. Water, coffee, cookies and good lunch included with the possibility to buy sodas/beers. Toilets on board, funny and good crew on board and hotel pick-up/drop-off. They took so many pictures and made sure that everyone who wanted photos had their photos taken, the next day we got the photos via link free of charge. Even without Nang Yuan, this was a 10/10 trip that is highly recommended.

Amazing experience cruising around the island on the Oxygen boat. Great facilities with good washing facilities especially for your snorkel mask ready for the best viewing experience of the local wildlife. Experienced crew with great English and knowledge of the local area and wildlife you will see on the day. Guides would swim first to guide you to the best spots and animals. Seen amazing reefs, baby sharks, large turtles, pink clownfish and many more! Would recommend this trip to anyone, Koh Toa is a beautiful place!
