Bio Rock
Bio Rock is an artificial reef with weak electrical currents flowing through its conduits to promote the growth of coral seedlings. Located off the coast of Koh Tao, opposite the Japanese Garden, this unique dive site is something truly special that Koh Tao has to offer.
You can see many coral fish such as butterfly fish, bannerfish, anemone fish and parrot fish. There are many corals growing on the structure itself, as well as along the coast.
