Where it is

The circle shows the general area, not the exact start. Use the directions link below to get to the car park itself. Contours and paths shown are OpenTopoMap, drawn from OpenStreetMap data.

The route

A track climbs from the road to the lake in around forty minutes. From there a steep path gains the escarpment edge and can be followed round over Picws Du and back down, making a horseshoe.

Worth knowing

  • The escarpment edge is a genuine drop. In wind or cloud, stay well back.
  • This is the western end of Bannau Brycheiniog and feels far emptier than the Pen y Fan end.
  • No facilities of any kind. Nearest anything is Llangadog.

What you’ll see

The lake in its cwm, the curving ridge of Bannau Sir Gaer, and red kites overhead.

Background

The Lady of the Lake legend places the physicians of Myddfai here, a family of healers whose remedies were written down in the thirteenth century.
