Why it's Wildland
6.4A lake reached through the wooded Cwm Mynach valley, with woodland tracks, streams and mountain views along the way.
The draw here is the journey into a quiet Rhinogydd valley: woodland paths lead past streams towards the lake, with mountain scenery opening around it. It has a stronger sense of place than a roadside viewpoint, but check access and conditions before travelling.

Pause for the stream and mountain views
