The Bida’s

Koh Bida NaiKoh Bida Nok

Koh Bida Nok, Koh Bida Nai, and Hin Bida are collectively known as The Bida’s.  Hin means rock, and is usually used to describe a submerged reef.  They are the same distance away from Lanta as Koh Haa, but due to their close proximity to The Phi Phi Islands, tend to be busier than Koh Haa.  The sites, however, never become crowded as the Phi Phi dive centres also use the sites around Phi Phi Lei a lot.

Bida Nok and Bida Nai have vast quantities of fish.  One could be 2 metres off the reef wall and not see the reef for fish!  The predatory fish can be seen hunting here in big numbers, and they’re not scared of divers.

Bida Nok has a small bay with a bottom at around 7-8 metres, ideal for courses.  Bida Nai has a lot of relatively big black tip reef sharks.  Leopard sharks are seen on most dives at any of the Bida’s, as are sting rays.
