Ao Phang-Nga Marine National Park
Ao Phang-Nga Marine National Park information
Established in 1981 and covering an area of 400 sq km, Ao Phang-Nga Marine National Park is noted for its classic karst scenery, created by mainland fault movements that pushed massive limestone blocks into geometric patterns. As these blocks extended southward into Ao Phang-Nga, they formed more than 40 islands with huge vertical cliffs. The bay itself is composed of large and small tidal channels that originally connected with the mainland fluvial system. The main tidal channels – Khlong Ko Phanyi, Khlong Phang-Nga, Khlong Bang Toi and Khlong Bo Saen – run through vast mangroves in a north–south direction and today are used by fisherfolk and island inhabitants as aquatic highways. These mangroves are the largest remaining primary mangrove forest in Thailand. The Andaman Sea covers more than 80% of the area within the park boundaries.
