About this site

Hin Wong Bay sits on the northeastern coast of Koh Tao, an island in Surat Thani province in the Gulf of Thailand. The bay is known for its boulder-strewn shoreline, and dive access there typically runs from shore out over a reef bottom into the bay itself, reaching a maximum depth of around 30 metres. It's rated a beginner site, and parrotfish are common on the reef, with fusiliers and unicornfish also spotted by divers here.
