Myanmar faces two seas: the Bay of Bengal and the Adaman Sea. The Rakhine coastal strip faces the Bay of Bengal (Bingala Pinle Aw) and stretches for 750 kilometres from the mouth of the Naff River on the Border with Bangladesh towards Mawtin Point (Cape Negris). The northern part is shallow but the southern part is more or less rocky. The continental Shelf, up to 200 metres in depth, is narrow compared to other areas. The Yanbye and ManAung Islands are two of the well-known islands in the area.
The Deltaic coastal zone is from the tip of Mawtin Point to the mouth of the Thanlwin River. The Ayeyarwaddy delta is formed by the numerous outlets of the Ayeyarwaddy River. Also the Sittaung and the Thanlwin Rivers empty into the Gulf of Mottama. It is estimated that this area is expending at the rate of 5 kilometres every hundred years due to the enormous deposits of silt being carried down by these three large river systems.

Another coastal area of the country is the TaninThayi coast. Previously it was called Tenessarim and faces the Andaman Sea known to the Myanmars as "Cutpali Pinle". The coastal stretch is about 1200 kilometres unit it reaches Bayint Naung Point (Victoria Point) opposite Ranong in Thailand. Kawthaung is the southernmost town of Myanmar situated on the tip of the peninsula. The Myeik Archipelago is dotted with more than 800 small islands mostly uninhibited.
Coastal and marine ecosystems such as mangroves, corals reefs, sea grass beds, estuaries, upwells and marine organisms migratory routes play a major role in the biodiversity of these areas. While coral reefs, sea grass beds and mangrove forests are abundant in the Myeik Archipelago, vast mud flats and estuaries are see on the deltaic area. Rippling white sand beaches and dunes occur throughout the whole coastline.
As it is the white rippling sand beaches, the emerald green tropical jungles and the blue waters of the Myanmar coastline are waiting for you to discover.
