Most famous is Ao Phang-nga National Park, a geological wonder filled with islets, sunken caverns and startling rock formations rising sheer out of the sea. The bay is extremely sheltered ideal for expeditions of sea canoes to explore the many fascinating caverns with their own eco-systems.
Phang-nga's andaman coast offers parks of a different kind. The island groups of Surin and Similan are renowned for their beautiful unspoilt beaches and spectacular underwater scenery, attracting divers from around the world. Khao Lak is a coastal park full of birds, mammals and scenic waterfalls.
