Phang Nga is a province equally renowned for its beautiful land, spectacular bay, and amazing islands; Phang Nga national parks feature magnificent scenery with immensely different attractions. Most famous is Phang Nga Bay National Park, a geological wonder filled with islets, sunken caverns, and startling rock formations rising vertically out of the sea. The bay is extremely sheltered and therefore ideal for expeditions on sea kayak that explore the many fascinating caverns and islands throughout the bay. Phang Nga's Andaman coast offers equally stunning national parks of a different kind; the island groups of Surin and Similan are renowned for their beautiful, unspoiled beaches and spectacular underwater scenery, attracting divers from around the world. On the Phang Nga mainland, Khao Lak features a coastal park full of rare birds, exotic mammals, and scenic waterfalls, as well as many luxury and budget hotels along the spectacular coast that was devastated by the 2004 Tsunami but has since been completely rebuilt.
