Koh Bida Nok is a premier diving destination located off Koh Phi Phi in Krabi, Thailand. This dramatic limestone pinnacle rises from the Andaman Sea, offering exceptional underwater topography with steep walls and thrilling vertical descents. Divers explore stunning rock formations, underwater caves, and crevices teeming with marine life.

Visibility typically reaches 15-30 meters, revealing vibrant coral gardens and diverse species. Marine encounters include reef sharks, groupers, snappers, trevally, sweetlips, and occasional barracuda schools. Macro life like nudibranchs and crustaceans populate the rocky surfaces.
