Bilauktaung Range

The Bilauktaung Range rises along the Malay Peninsula between the Andaman Sea and the Gulf of Siam. Forested ridges and deep valleys separate the Tenasserim coast from the plains of Siam. Routes across the mountains linked the port of Mergui and the town of Tenasserim with settlements on the eastern shore, allowing goods and travellers to cross the narrow peninsula. The rivers of the western slopes descend towards the Andaman Sea.
