Llyn Cwm Llwch
Llyn Cwm Llwch is the best preserved glacial lake in South Wales. There are many legends about the lake and the fairies that live on an invisible island in the lake.
This walk takes you through the Cwm Llwch valley to this popular beauty spot in the Brecon Beacons National Park.
The walk starts at the car park near the lake and involves a steep climb along the Cwm Llwch river to the beautiful lake. The surrounding scenery of the Brecon mountains is simply stunning.

Wild camping at Llyn Cwm Llwch. A popular wild camping spot, as it is sheltered and level.
The footpath to Llyn Cwm Llwch. The red earth footpath leading down to the tarn in the valley can be seen winding its way along the edge of the ridge which descends from Corn Du.
This photograph shows how the shallower parts of the tarn have a rich browny-red hue as a result of the bedrock (Old Red Sandstone) of the Beacons. The ridge on the other side of the tarn is moraine material.
Track to Cwm-llwch, near the start of the walk.
The footpath descending Pen Y Fan via Cwm Llwch. This part of the path crossed through land which is 'humpy' and dotted with gnarled trees. A lot of the little numps and ridges appeared to be man made but I'm not sure of their purpose. The high ground in the background is the northern ene of Cefn Cwm Llwch.
