Oxygen Tour runs two morning snorkelling boats around Koh Tao from Mae Haad, and the choice between them comes down to one island: Koh Nang Yuan. The Early Bird boat skips it and costs ฿990 (≈ $27); the premium boat stops there for an hour and a half and costs ฿1,390 (≈ $38) plus a ฿250 island fee. Prices were read on the operator's site on 1 October 2026.

  • The Early Bird: four bays and back at noon
  • The premium boat: Koh Nang Yuan and a buffet
  • What children pay and what to carry in cash

Important

No Oxygen ticket includes the Koh Nang Yuan fee. On the premium trip it is ฿250 per person, paid in cash at the check-in office.

What does the Early Bird trip include?

The Early Bird trip costs ฿990 (≈ $27) per adult and ฿690 per child over 3. A taxi collects you at 07:30, the boat leaves Mae Haad at 08:00 and you are ashore at noon. The four stops are Tao Thong Bay with green staghorn coral, Freedom Bay under Buddha Rock, Aow Leuk, where coffee is served, and Shark Bay with its green turtles. A lunch box, chicken or vegetarian, and a mask and snorkel are included; the boat takes up to 45 people.

Because the route does not land on Koh Nang Yuan, there is no island fee. Next to the ฿990 (≈ $27) price the page shows a special-price label without a figure, so check the price on the day you book.

What does the premium boat add?

The premium trip costs ฿1,390 (≈ $38) per person and is limited to 25 guests. Pickup is at 08:00 and the boat leaves at 09:00. The first stop is Japanese Garden, a coral garden in the bay off Koh Nang Yuan, then an hour and a half on the island itself, three islands joined by a white sandbar with a viewpoint at the top. Lighthouse or Mango Bay, Aow Leuk and Shark Bay follow, and lunch is a Thai buffet on board.

The schedule shows the return at 15:00; the description on the same page talks of being back at noon, so plan for 15:00. Children over 3 pay the adult rate. Bring a small bag, sunscreen, insect repellent, a hat and cash for drinks on Nang Yuan.
