Teifi

The Teifi, or Afon Teifi in Welsh, is a major river in western Wales. It rises in the Cambrian Mountains in mid-Wales and flows generally westward to the sea, discharging into Cardigan Bay at Cardigan (Welsh: Aberteifi). Along its course it passes through Llandysul and Newcastle Emlyn before reaching the lower estuary.

Notable features along the lower Teifi include Cilgerran Gorge, a dramatic river gorge near Cilgerran, and Cenarth Falls, a waterfall near Cenarth. The estuary forms a broad, shallow outlet at Cardigan Bay.

The Teifi supports migratory fish such as Atlantic salmon and sea trout, and hosts species such as otters and various birds in its tidal reaches. Historically, the river powered mills and supported local industries; the towns along the Teifi, including Cardigan and Cilgerran, reflect its historical economic importance.

The river is central to the culture and landscape of west Wales, with the Welsh name Afon Teifi and the town of Cardigan (Welsh: Aberteifi) situated at its estuary. The Teifi valley has been associated with Welsh literature and language in the region.
