This compact 21 km² island forms part of the Chumphon Archipelago on the western shore of the gulf of Thailand.
Whilst this island is small in size, the underwater scenery is grand with coral-encrusted rock pinnacles, vibrant reefs and great shipwrecks. Stingrays and grouper are always lurking with lucky divers catching a glimpse of a whale shark or eagle ray. When you’re not looking out to the blue, you’ll be mesmerized by the plethora of colorful reef fish all around you whilst diving in Koh Tao.
Cruise along the pinnacle with huge schools of chevron barracuda, yellow snapper and big eyed trevally, penetrate the wreck of a military vessel or hang out with the giants groupers - diving in Koh Tao brings delight to all divers.
Koh Tao’s calm, bright waters provide stable conditions throughout the year and with around 300 days of sun and water temperatures never dropping below 84°F/29°C, you can see why it's a diver favourite.
You can appreciate rock and coral formations, as well as titan triggerfish, sea snake, hawksbill and green turtles at any time of year when diving in Koh Tao. Whale sharks cruise into the deeper pinnacles through all seasons, but are most likely to appear in April and May.
July-September sees visibility stretch to 30 meters. Macro lovers will spot critters, nudibranch and three species of shrimp inside crevices and gaps between rocks. Divers with a good eye will also notice them on the artificial reefs.
