What To Expect

1

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.

    Had the best day! Hotel pick up was arranged over message the night beforehand. All equipment was provided with clear guidance throughout the day. Went to five different sights, seen loads of fish and coral. Even found Dimitri the turtle and had a picture taken for free. Outstanding tour!

    So much to see.. by far the best snorkeling I've done in Asia. Very impressive. There is alot of people on the tour so if you want a smaller tour you should book the 25 person small group tour. It was still great though. We saw 2 turtles, anemones and so many amazing fish. Loved it.

    The boat was a completely different boat than described, food was left out in the sun and became inedible, the driver was smoking bongs whilst driving and the guide didnt explain anything properly. Viator did nothing to help.

  • Way too overcrowded, low quality

    Pretty basic, main issue was they had >100 people to manage so very overcrowded. Unless you want to keep things quite cheap, better to just get a taxi boat around the island and do some snorkelling.
