Afon Crafnant

The 883rd longest river in the world

km

Afon Crafnant (Welsh for 'River Crafnant') is a tributary of the River Conwy, which is the main river of the Conwy valley in north-west Wales. It flows from picturesque Llyn Crafnant, joining the river Conwy at Trefriw. It is about 2.5 miles (4.0 km) in length. The river Geirionydd is a tributary which flows from Llyn Geirionydd. They have a confluence a little below the former Klondyke Mill, which used water from both rivers. Klondyke was a mining and milling complex connected with some of the metal mines of the Gwydir Forest. The Crafnant is also fed by a number of unnamed streams draining from Cefn Cyfarwydd, the ridge to the north-west. At Trefriw some water from the river is extracted to pass through the Trefriw Woollen Mills to generate hydro-electricity for the machinery, after which the river flows over the Fairy Falls, a popular attraction. Coed Crafnant, an area of woodland in the valley, is managed by the North Wales Wildlife Trust.

Flows through: United Kingdom.
