Aow Leuk dive site, Koh Tao, is a naturally sheltered bay on the south-east coast of Thailand’s diving island, protected from strong winds and open-sea swell. This shallow site, averaging just 6 metres with a maximum of 12 metres, offers extraordinary underwater scenery and an abundance of young marine life. Garden eels swaying from the sandy floor, perfectly camouflaged scorpionfish, coral patches alive with butterflyfish and yellowtail barracuda schools: Aow Leuk is a site for all levels that consistently rewards the patient observer.

Aow Leuk dive site Koh Tao: a preserved bay on the south-east coast

Aow Leuk, which means “deep bay” in Thai, sits on the south-east coast of Koh Tao. Naturally sheltered from prevailing winds and open-sea swell, this bay creates exceptionally stable diving conditions year-round. As a result, it suits both beginners and experienced divers who enjoy taking their time underwater. Just 40 minutes by boat from Mae Haad pier, Aow Leuk offers stunning scenery in one of the most tranquil settings on Thailand’s diving island.

At an average depth of just 6 metres with a maximum of 12 metres, Aow Leuk ranks among the most accessible dive sites on Koh Tao. Nevertheless, its shallow profile is deceptive. Thanks to the diversity of marine life here, particularly the characteristic garden eels on the sandy floor, this site rewards divers on every single visit.

The garden eels of Aow Leuk, the signature of the site

Without doubt, the most distinctive feature of Aow Leuk is its garden eels. These slender sea animals live half-buried in the sand, swaying gracefully in the current to filter nutritious particles. In addition, they form dense colonies across the sandy floor of the bay. Approach too quickly and they vanish into the sand. Move slowly, control your breathing, and you can observe them from just a few centimetres away.

Moreover, the sandy bottom hides another fascinating resident: the scorpionfish. This master of camouflage blends perfectly into its surroundings and reveals itself only to the most attentive eye. Indeed, it is this bottom-dwelling fauna, observed slowly and patiently, that gives Aow Leuk its unique character among Koh Tao’s dive sites.

Marine life at Aow Leuk Koh Tao: what you’ll encounter

Aow Leuk combines two complementary worlds. On one side, the sandy floor hosts a rich community of bottom-dwelling species. On the other, scattered coral patches shelter colourful reef life. Together, these two environments make Aow Leuk a complete and varied destination for divers of every level.

What level do you need to dive Aow Leuk Koh Tao?

Aow Leuk is accessible to all levels, from complete beginners on a Try Scuba experience to Advanced Open Water certified divers. Its shallow depth (6 metres average, 12 metres maximum), near-absent current and naturally sheltered bay make it one of the most comfortable and reassuring dive sites on Koh Tao for first-timers.

Experienced divers equally appreciate Aow Leuk for its patient, observation-focused style of diving, particularly the garden eels and scorpionfish on the sandy floor. Furthermore, the combination of sandy bottom species and coral patch life makes it a natural fit for the SSI Underwater Photography specialty course.
