|Location||South-eastern Eriador, separating Eregion from Enedwaith|
Beginning in the Hithaeglir south of Khazad-dûm, it flowed west-north-west until it was met by the Sirannon near the old location of Ost-in-Edhil, the capital of the Noldor of Eregion. From there the Glanduin flowed westward towards the Mitheithel, which it met in the Swanfleet marshes (Nîn-in-Eilph) north-east of Tharbad. There was an old ford across the Glanduin east of the falls that dropped down into the marshy lowlands.
Beyond their joining both rivers became the Gwathló.
The name "Glanduin" applied to the whole river during the time of Eregion and Arnor. However, by the time of the War of the Ring, it only applied to the swift upper course of the river, and usually it was referred to as the Swanfleet river (not River), simply meaning the river that flowed into the Nîn-in-Eilph.
