Practical
Position: OpenStreetMap outline of Ko Bi Da Nai. Walls on the north and west drop to 20 m or more; the east side drops 5-8 m before sloping to sand; the coral garden at the south end starts at 5 m (Sharkey Scuba). Sunrise Divers gives 8 to 28 m for the Bidas. Life: leopard sharks on the sand near Fantasy Reef, blacktip reef sharks in the shallows, seahorses, frogfish, octopus, turtles; whale sharks pass in season. Suitable for all levels. Inside the national park: no anchoring on coral, park fee; the Pilot gives no yacht anchorage here. Approaching from the south, avoid Hin Bida about 3 nm southeast of Koh Bida.
