According to legend, Cader is named after a giant called Idris Gawr. 'Cadair Idris' means 'Chair of Idris' in English, while 'Cader' can also refer to an ancient fortress. The place is known as Cader Idris rather than Cadair, but both names are used. The most famous local fable is that if you spend the night on the mountain, you will go mad or become a poet.

Cader Idris is composed of Ordovician sedimentary and igneous rocks. Llyn Cau, which lies at the bottom of the crater-like Cwm Cau, was formed by a cirque glacier during several ice ages. The glacier was once a square kilometre in size. (Eryri National Park Authority)

Beautiful view of the mountain lake Llyn Cau. It is a 350-meter climb from the car park, past numerous waterfalls and pools, so even if the lake is cold, you will be warm when you arrive.
