Ao Yui - Koh Tao

Ao Yui sits off Koh Tao's west coast, a shallow dive spot at just 14 metres deep. It’s perfect for beginners and those looking for a relaxed, easy dive. You’ll find a sandy bottom with a smattering of corals and small rocky outcrops, often hosting groups of fusiliers and rabbitfish. It’s a good place for macro spotting, too, if you take your time.
