Amongst the islands in the Andaman Sea, are the Koh Phayam Islands, a national marine park in Ranong province. Koh Phayam is the second biggest island after Koh Chang. It’s a natural beauty in the middle of the deep, beautiful sea, and is most famous for its ecotourism. Its splendors range from cool and pleasant pine forests to wide, white beaches, to clear water, to a colorful underwater world. In the middle of the island is a mountainous forest area filled with various plants and animals. Other parts have been converted into coconut orchards, rubber tree plantations and, the most delicious, cashew nut orchards. This gorgeous little island is truly the undiscovered pearl of the Andaman Sea, with long white sandy beaches, clear blue sea, coral reefs, it's the perfect place to really get away from it all. The two main bays are Aow Yai, the sunset bay, and Aow Khao Kwai - (Buffalo Bay). Both bays have long curving white sandy beaches.
