"CADER IDRIS, one of the principal mountains in Wales, situated in the county of Merioneth, to the S. of Dolgelly, from which the summit is distant about 5 miles. The ridge, which is about 10 miles long from N.E. to S.W., consists chiefly of basalt, with traprock, felspar, &c. It is of a very rugged and precipitous character. The summit is bare of vegetation and divides into three peaks, the loftiest of which is called Peny-Cader, and has an elevation of about 2,900 feet above the level of the sea. The others are called Mynydd Moel, or the "bald mountain," and Craig-y-Cae. On the S. side of the mountain, in a lovely spot, is a small lake called Tal-y-Llyn, and on the same side, halfway up, is another lake or tarn, called Llyn-y-Cae, shadowed by steep and lofty rocks.
The northern base of the mountain touches the sea and the beautiful estuary of Barmouth. The view from the summit is of great extent, and in some respects rivals that from Snowdon. In clear weather it embraces the whole coast of Cardigan Bay to the S.; and Bala Lake to the N.E.; the Snowdon mountains to the N., and Plinlimmon to the S. The beautiful Vale of Dolgelly immediately below, and the estuary of Barmouth, forming a charming relief and setoff to the wild grandeur of the environing mountains. One of the finest views of the Cader Idris is had in approaching it from Machynlleth, along a fine wooded valley, watered by a branch of the river Dovey. The name of this mountain signifies "Chair of Idris: "Idris being a fabulous personage, variously represented as a giant, poet, or prince."
