The Lhûn River System
The River Lhun (Lune) begins in the eastern Blue Mountains and flows southward into the Great Sea in the Gulf of Lhun. The Grey Havens stand near the mouth of the River Lhun. The Lhun has two tributaries: Annuduin springing from the Blue Mountains and Vialduin from the western Hills of Evendim.
Gulf of Lhun is the gulf of the Great Sea where the River Lhun outflows, separating the lands of Forlindon to the north and Harlindon to the south. The Grey Havens lies at the eastern end of this gulf.
