Llyn Crafnant, Snowdonia National Park

Llyn Crafnant is a lake that lies in a valley in Wales where the northern edge of the Gwydir Forest meets the lower slopes of the Carneddau mountains and, more specifically, the ridge of Cefn Cyfarwydd. The head of the valley offers a profile of crags which are silhouetted at sunset. The Forest Park guide states that "the is one of the most breathtaking views in all Snowdonia". The summits include Crimpiau 475 metres, and Craig Wen 548 metres which provide views to Moel Siabod and the Ogwen Valley, and Snowdon. Further up is Creigiau Gleision. At 63 acres it is the best part of a mile long, although it was clearly once much longer - its southern end shows the evidence of centuries of silting. Jehu's survey recorded a maximum depth of 71 ft. ()
