Cadair Idris is one of the Southernly peaks of Eryri (Snowdonia). It sits magnificently at the head of the Tal-y-Llyn pass, and above Dolgellau to the North, with its craggy slopes rising above the tree-line towards the mystical clouds that so often shroud its summit. This mountain is rich with mythology and legend; meaning 'Chair of Idris', it takes its name from the mythical giant king 'Idris Gawr' who was once said to sit atop the mountain and marvel at the heavens.

The lake found at the centre of the seat is said to be bottomless, and the surrounding slopes to be the hunting grounds of the Welsh king of the underworld, Gwyn ap Nudd and his Cwn Annwn. But one of the most intriguing legends owes its existence to the great bardic heritage of Wales. This legend comes as a warning to any wandering soul that might find themselves upon the mountain's slopes at night, for anyone that spends the night on the mountain will come down either a madman or a poet.
