Bay of Belfalas
Type: Seas, Oceans, Bays
An enormous bay of the Sundering Sea, stretching from the cape of Andrast in the north to Harad, several hundred miles southwest of Umbar, in the south. The rivers of Gondor that empty into the Bay of Belfalas are: Lefnui, Morthond (with tributary Ringló), Serni (with tributaries Ciril and Gilrain), and Anduin; and the Harnen empties into it from Harad.
Isen and Lefnui... formed the north arm of the Bay of Belfalas [Ras Morthil 1 or Andrast]....

[Aldarion]... began to explore the coasts southwards [of Mithlond], past the mouths of Baranduin and Gwathló and Angren, and he rounded the dark cape of Ras Morthil and beheld the great Bay of Belfalas, and the mountains of the country of Amroth where the Nandor Elves still dwell.

[The Haradrim] contested the designs of Gondor to occupy the coast-lands beyond R. Harnen; they therefore tried to take Umbar, where Gondor maintained a great fort and haven.

In the days of the earlier settlements of Númenor... [the] shores of the Bay of Belfalas were still mainly desolate, except for a haven and small settlement of Elves at the mouth of the confluence of Morthond and Ringló.

End of Second Age
[The shores of Middle-earth] were much changed in the tumult of the winds and seas that followed the Downfall; for in some places the sea rode in upon the land, and in others it piled up new coasts.... [The] Bay of Belfalas was much filled at the east and south, so that Pelargir which had been only a few miles from the sea was left far inland, and Anduin carved a new path by many mouths to the Bay. But the Isle of Tolfalas was almost destroyed, and was left at last like a barren and lonely mountain in the water not far from the issue of the River.

And when the wind is in the South the voice of Amroth comes up from the sea; for Nimrodel flows into Silverlode, that Elves call Celebrant, and Celebrant into Anduin the Great, and Anduin flows into the Bay of Belfalas whence the Elves of Lórien set sail.
