Route
It rises from a source in the hills above Aberllefenni and passes through Corris, Esgairgeiliog and Pantperthog before joining the Afon Dyfi at Ffridd Gate near Machynlleth.
History
The Dulas is recorded as an important land boundary in 1200, in a document written in 1428. This document describes the land owned by Einion ap Seisyllt, in the time of Llywelyn the Great, as "tota terra inter aquas de Dyfi et Delwas" (Latin, meaning: all the land between the rivers Dyfi and Dulas).

South Dulas
Another river also called the Afon Dulas joins the Dyfi from the south, upstream of its confluence with the North Dulas. Locally this is referred to as the South Dulas. It rises in Glaslyn, below the slopes of Foel Fadian, and passes the hamlet of Forge and Plas Dolguog before joining the Dyfi.
Close to its confluence with the Dyfi it is crossed by the Cambrian rail line on a bridge known as the Black Bridge. After the line had been repeatedly closed due to flooding after heavy rain, in 2021 it was announced that the bridge and its approaches were to be raised by a metre to try and alleviate the problem.
