Tucked between southern Thailand's mainland and Phuket Island, Phang Nga Bay is a fantastic day-trip destination for tourists in Khao Lak. Boasting dramatic karst landscapes, magnanimous caves and turquoise lagoons, this archipelago is dotted with coral reefs and mangrove forests. Among Phang Nga's small islets, James Bond Island and national park is a pilgrimage for 007 fans, with picturesque 66-feet-tall limestone cliffs.
