River Glanduin

The river that flowed down into Swanfleet

Map of the River Glanduin
The course of the River Glanduin (slightly conjectural)2

The river that rose in the Misty Mountains, south of Khazad-dûm. It flowed westward to meet the Hoarwell above Tharbad, where it formed the marshland known as Nîn-in-Eilph or Swanfleet.



In the Second Age, the Glanduin formed the southern border of Eregion, and this was the reason for the name. In the Third Age, it came to mark a different border, the southern boundary of the North-kingdom of Arnor.


The course of the River Glanduin itself is well established, but that of its tributary the Sirannon is less certain. It seems inevitable that it must have flowed into the Glanduin, but its exact course is not known.
