Phang Nga Bay or Ao Phang Nga, is one of the most beautiful places in southern Thailand. It is a place of majestic karst islets scattered across a bay area northeast of Phuket. Due to its significance, Phang Nga Bay was designated as Phang Nga Bay National Park. Phang Nga Bay National Park covers an area of 400 square kilometers and encompasses the largest tract of mangrove forest in Thailand. It stretches from Muang Phangnga District to Takua Tung District. Within this area are about 42 islands, the most famous being Koh Khao Phing Kan (better known as James Bond Island), Koh Tapu and Koh Pangyi. Within the bay are massive karst outcrops that extend southward into Phang Nga Bay, where they jut out of the sea as towering limestone islets. Many of these karst islands have almost vertical cliffs. The bay itself slopes southwards and composed of large and small tidal channels fed by the rivers. A distinctive feature of Phang Nga Bay is the sheer limestone cliffs that jut vertically out of the emerald green water. Phang Nga Bay is best explored through an ecological tour package which can be arranged with a responsible tour agent in Phuket.
