River Cynfal

The River Cynfal

The River Cynfal is a mountain river of Merionethshire, running off the Cambrian Mountains and becoming ultimately a tributary of the River Dwyryd, one of the two main rivers (with the Glaslyn) feeding the head of Tremadoc Bay.

The Cynfal is beautified by waterfalls, the best known of which are the Cynfal Waterfall and the Rhaeadr y Cwm.

The headwaters of the Cynfal rise on the upland moorland known as Migneint, whgich is the source of several rivers, including the Conwy and several of the headwater strems of the Dee. The Afon Gam and the Nant y Groes join below the moor to create the Cynfal, whose waters soon afterwards tumble over the Rhaeadr y Cwm.

The river flows westwards, south of Llan Ffestiniog to join the Dwyryda mile and a half from its tidal limit.
