Llyn Cau has an ambience all of its own. This is a beautiful high mountain pool watched over by the frowning cliffs of Craig Cwm Amarch and Penygadair, Cadair Idris' main summit.

Like Snowdon's Glaslyn, legend tells of a terrifying serpent, the Afanc, in the depths of the water. It's easy to imagine serpents, dragons and giants in a landscape such as this, which is probably why Cadair Idris is so rich in myths and legends.

This is the lake surrounded by the Cadair Idris range. Its spectacular colour is only really appreciated from way above on the ridge, however this is a good stop for a quick break or even a swim if you are brave enough.

Legend of Cadair Idris
Local folklore describes Idris as a giant who lived on this magnificent mountain; Cadair Idris is Welsh for “Idris's chair”.

The large boulders on the lower slopes are supposed to be the debris from stone throwing battles between Idris and the other giants.

It is said that if you are lucky enough to survive a night on the summit, the ordeal will either drive you mad or turn you into a poet.
