What To Expect
Koh Tao
Choose between a morning departure for early risers who don't want to miss the beautiful morning light, or an afternoon departure for people who prefer to sleep late but still want to explore Koh Nangyuan and Koh Tao - remember that the afternoon trip is usually less crowded. Meet the friendly boat crew of the Oxygen at Mae Haad Pier and get useful information about the trip and the islands. With all the exhaustion of the sightseeing, sunbathing, and snorkeling, you’ll need to have lunch to refuel while cruising to Koh Tao onboard the Oxygen. Some of Koh Tao’s most beautiful beaches dot the East coasts which are difficult to reach by road. That makes these beaches the perfect destinations for this boat trip. You will make several sorkel stops at Mango/Lighthouse Bay, Hin Wong Bay with colorful fishes and in Ao Leuk which is famous for its crystal clear water. The last snorkel adventure will be at Shark Island named for it’s supposed fin-like shape.
First cruise to the stunning Nangyuan Island which takes just a few minutes onboard the big boat from Koh Tao. Take the 15-minute hike up to the viewpoint of the three islands’ highest peak. The view from the top, a vista that graces postcards across the country, is one of the most beautiful you will have ever laid eyes on. • 09:00 - 09:30: Hotel pickup on Koh Tao • 09:30 - 10:00: Meet the boat crews & check in at the pier • 10:00 - 10:30: Depart from Mae Haad Pier to Nangyuan Island • 10:30 - 11:30: Climb up to the viewpoint, relax & swim at Nangyuan Island

4.00Overall a nice trip with friendly staff. You get all the way around the island. Includes lunch. The toilets aboard the ship need a loving hand, and there is no possibility of washing hands. They could well put hand spit out when serving the buffet to reduce the bacteria.
Great snorkeling trip!

5.00Everything was very smooth, we booked the day before directly with the snorkeling center for the next day. They picked us up and took us to the boat. The team on the boat was very friendly and accompanied us well during the few hours on board. They then took us back to our hotel. I recommend!
To do!

5.00A great day I spent with my friend! We were about forty on the boat, super well received and very well organized. The boat tour is great, you have advice, one person who will guide you if you want for snorkeling, the meal is delicious on board, the whole team is taking care! The price is downright profitable considering the great outing as well as the pictures you can have at no extra charge a few days after the excursion. I recommend without hesitation, super safe and pleasant!
Most amazing snorkel experience

5.00We, a team of 11 pax, had an amazing experience with Oxygen Tour Koh Tao! The team was incredibly helpful and hardworking from start to finish. they made sure everyone was safe throughout the trip. Our guide was not only passionate and knowledgeable about the sea corals and fishes but also made the whole experience so fun and memorable. Their attention to detail, excellent customer service, and impressive underwater photography truly stood out. Highly recommend to anyone visiting Koh Tao! one of the best snorkeling experiences ever! 🌊🐠💙 Will definitely use their service if I am coming here again!
