About Koh Bida Nok
Koh Bida Nok is a signature Phi Phi boat dive with a gently sloping reef, a stronger southwest wall, and a shallower northern side that leads into a lagoon-like area. Coral cover is strong, and the site is known for turtles, blacktip reef sharks, barracudas, snapper, stingrays, and dense schools of reef fish. It is a classic day-trip dive that rewards good buoyancy and attention to current on the wall.
