Shark Bay, Koh Tao
(Thian Og Bay)

Share

Thian Og is a lovely, quiet place to come and relax. It is known as ‘Shark Bay’ due to the blacktip reef sharks that frequent here. An entrance fee is charged. You can also visit the bay by boat or kayak. Alternative ways of access can be found via a few resorts in Chalok Baan Kao Bay’s east coast that connect to Shark Bay’s west shore (not at the main beach). This area is also a shark nursery where young sharks can be seen at certain times of the year. There are larger sharks, and to see them you need to swim out about 250 metres from the beach to where it drops down deeper to 3 – 4 metres. They are more likely to be found around the east shore close to Sai Daeng Beach.

Look out for green turtles as well, as these live in this bay too and are amazing to see. A few of them are huge, larger than a metre long. They are friendly and not afraid of humans and can sometimes swim very close to you. Please be sure to not touch them as bacteria on our skin can greatly affect their health and can cause them harm. Though the coral reef in the bay was vastly destroyed by El Nino in 1998, Shark Bay is the only place where you can find turtles every day.
