Recommended by LUM. Oxygen is our island snorkelling partner. Tell us you'd like to snorkel and we'll make the introduction and sort the details before you arrive.
Why Oxygen
Want to see Koh Tao underwater? We send our guests to Oxygen — the island's leading sustainable snorkelling operator. Calm mornings on the water, the island's best reefs, and a team that genuinely cares about the sea you've come to see.
Their motto says it all — "Green is Life, Oxygen Makes It Happen." No single-use plastic, reusable cups, an eco briefing before you jump in, and waste separation and composting back on shore. You get an unforgettable day; the reef gets looked after too.
And the best part for the memories: free photos on every trip — surface and underwater — so you can be fully in the moment and still take the whole day home with you.
The Oxygen experience
The Go Green Project — no single-use plastic, reusable cups, eco briefings, and composting on shore.
Surface and underwater shots included — be in the moment and still take the day home.
Pick a limited-guest premium trip for more space, or charter a private boat entirely your own.
Koh Nang Yuan, Japanese Gardens, Shark Bay, Hin Wong and more — bright coral and turtles.
The trips
On the water
The quiet magic hour. Glassy water, soft light and the reef to yourselves before the day boats arrive — the snorkellers' favourite.
The classic island snorkel loop, capped at a small number of guests so it never feels crowded — more room on the boat and in the water.
Koh Tao's greatest snorkelling hits in one morning — Koh Nang Yuan, coral gardens and turtle spots — on the lively big-boat trip.
A later start for slow mornings by the pool — same beautiful reefs, warm afternoon light on the water.
Make it yours
The whole boat to yourselves — pick the sites, set the pace, and go where the water's best. Ideal for couples, families booking neighbouring villas, or a group of friends.
Prefer to stay dry? A guided island loop of the best viewpoints and local cafés — an easy, scenic half-day on land.
Trip times and current prices change with the season and the tides — ask us or Oxygen for today's schedule and rates.
