Krabi is a province on Thailand's Andaman coast, famous for its dramatic karst limestone cliffs plunging into turquoise water, powder-white beaches, and the isolated paradise of Railay Beach — accessible only by boat because sheer cliffs cut it off from the mainland. The province is a hub for rock climbing, sea kayaking, diving, and island-hopping to Ko Phi Phi, Ko Lanta, and the Trang islands. Ao Nang town is the main resort base, while the Tiger Cave Temple and mangrove kayaking offer alternatives to the beaches.
