Phi Phi boat dive with wall, lagoon, and strong coral and shark life.
Phi Phi boat dive with wall, lagoon, and strong coral and shark life.
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.
Safety Notes
Watch the wall edge and current on the southwest side, and keep the lagoon section in mind as the easier fallback.
Community notes to help plan your visit.
Scuba Diving
The dive combines a shallow reef-and-lagoon feel on the north side with a stronger wall on the southwest, so the route can be matched to the day's conditions.
