River Gwili

The Gwili near Abergwili

The River Gwili in Carmarthenshire, is a tributary of the River Towy, the longest river entirely in Wales. Its headwater is found east of Llanllawddog, in the Brechfa Forest. It runs west, through Llanpumsaint, to its confluence with the River Duad, just south of Cynwyl Elfed village. Here its course turns to the south-east, running through Bronwydd before joining the River Towy at Abergwili.

The River Gwili gives its name to a number of settlements, as well as the West Wales General Hospital which is commonly known as Glangwili Hospital. The Carmarthen to Aberystwyth railway line once followed the course of the river between Abergwili and Llanpumsaint and the dismantled railway line can still be seen right along the valley. In 1978 a section of the line was reopened in Bronwydd for tourists and was given the name Gwili Railway.

The River Gwili is popular with both anglers and canoeists.
