Oxygen Tour Koh Tao

Oxygen is widely regarded as the best operator on the island. For NYE, their "Premium Trip" is the ultimate chill option. Unlike crowded boats, this trip limits passengers (max 20-25) and focuses on a relaxed pace. They are famous for their excellent guides who actually get in the water to point out the Blacktip Reef Sharks at Shark Bay and the huge Green Turtles at Aow Leuk. They prohibit single-use plastic and serve a delicious lunch onboard.
