Mythology and Folklore

Out of all the peaks in Snowdonia, Cader Idris is undoubtedly the most steeped in mythology. Countless legends are connected to this mystical summit and its surrounding lakes.

Cader Idris’ name, translated as Idris’ Chair, is often said to have been derived after a giant called Idris. Legend has it that Idris used the summit as a chair to survey his kingdom. Another theory suggests that the mountain is named after Idris ap Gwyddno, a 7th-century prince of Meirionnydd.

Many of the lakes around Cader Idris are supposedly bottomless, and it is said that, after spending a night on the peak, one would either wake up a poet or a ‘madman’.

Welsh mythology also suggests that Cader Idris was the hunting ground to Gwyn ap Nudd and his Cŵn Annwn. The howling of this pack of hounds foretold death to all that heard it—herding their soul into the underworld.

Geology and Biodiversity

Cader Idris is formed of sedimentary and igneous rocks from the Ordovician age. Llyn Cau, which sits at the bottom of the crater-like Cwm Cau was formed by a cirque-glazier across several ice ages. The glacier’s size was up to a square kilometre at one point.

Much of the area around Cader Idris is a designated National Naure Reserve—home to Artic-alpine plants such as purple saxifrage and dwarf willow.

Cader Idris on canvas

In the 18th century, Richard Wilson, an artist from Machynlleth, made the hike up to the shores of Llyn Cau at the foot of Cader Idris. Here he painted what is arguably his most well-known landscape painting.

It’s important to remember that these were the days before photography, and Wilson’s painting would have been the first time many had seen the landscape of Snowdonia.
