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

1.00ข้างเสียใจ กับเหตุการณ์แย่ๆ ที่เจอพนักงาน admin แถบจะไม่ช่วยเหลืออะไร เราเล่นสไลด์บนเรือ กางเกงขาด 99% มันใจเกิดจากสไลด์แต่เค้าก็พยายามบอกว่า คนอืนไม่เห็นแจ้ง คือ ระหว่างทริปเล่นสไลด์เราไม่รู้ว่าเกิดอะไรขึ้น แต่กลับมาห้องพักเจอกางเกงขาด รู้มันใจว่าเกิดจากการเล่นสไลด์เพราะกางเกงตัวนี้พึ่งใส่ครั้งแรกมีรูปให้ดูก่อนเล่นและหลังเล่น แต่บริษัทก็ไม่รับผิดชอบใดๆ รอคนอืนมาแจ้งคนอืนเค้าอาจจะไม่โดนเหมือนผมผมเล่น 3 ครั้ง เลยทำให้เสียหาย ปล.พนักงานบนเรือน่ารักมาก ผมแนะนำอย่าใส่กางเกงว่ายน้ำมีมูลค่าไปเพราะเกิดอะไรขึ้นบริษัทนี้จะไม่รับผิดชอบใดๆ ให้กับคุณ _________ I’m quite disappointed with the bad experience I had with the admin staff, who were barely helpful at all. I used the slide on the boat, and my swimwear was torn. I am 99% sure it happened because of the slide, but they kept saying that no one else had reported the same issue. During the trip, I didn’t realize anything had happened, but when I returned to my room, I found that my swimwear was damaged. I’m confident it was caused by the slide because it was the first time I had worn those shorts, and I even have photos from before and after the trip as evidence. However, the company refused to take any responsibility. P.S. The staff on the boat were actually very kind. My recommendation is: don’t wear expensive swimwear on this trip, because if anything happens, this company will not take responsibility for any damages.
See the Sea Turtles of Koh Tao

5.00Unbelievable experience, one I’ll remember for a while! We were lucky enough to see some beautiful marine life including a sea turtle and some baby sharks. We visited 5 stops on our afternoon tour around the various bays of koh Tao. All with lots of time to snorkel! The boat was nice and spacious for all guests including different areas to sit or lie down. The staff were so accommodating and informative! Also the food provided was delicious. Couldn’t fault it
Absolutely recommend!

5.00The tour was really great! You have really seen a lot and experienced during all the dive stops. In addition, the guides made a real effort and also guided you in the water. There was also food and there were photos taken both on board and underwater, which you then got for free. In addition, the transfer from the hotel and back was included. For all these achievements, the tour was very inexpensive.
Amazing 100% book this

5.00It was honestly incredible! The staff were amazing , so kind and helpful ( special shoutout to Tiger and Nam) . The team were very well trained in safety and we felt so looked after. They also took photos for us to have for free at the end of the trip . The water was choppy at some points but they rerouted and took us to another bay instead, we were really pleased they put our safety above anything but still took us to amazing spots. Really really reccomend !!!!
Great tour with great guides

4.00We were a lot of people, that's the only thing I could say I didn't like. But it was enough to go snorkel our roll on the side that not all the mugholone and the background was incredibly beautiful! One of the guides was the best, Nam. He helped us to see animals, took pictures and videos super nice, is very funny and told you even poses to pose in the photos. The best photographer! We had a good time although we did not get to see turtles but it was nice everything! I would certainly repeat
Great guides and equal experience
