Cwm Idwal and Glyderau, Snowdonia, North Wales
Llyn Idwal, measuring 800 metres long by 300 metres wide, is surrounded by towering high crags, screes, glacial moraines and wind shattered rocks. It is named after Idwal, the son of one of the ancient Princes of Wales, Owain, Prince of Gwyneddd, legend relates Idwal was murdered by being drowned in the lake. Tradition further states that no bird flies over the lake, as a result of Idwal's terrible fate.
The dark and brooding cliffs of Cloqwen y Geifr ( the Cliff of the Goat) form a dramatic backdrop to the lake. The plume of steam that rises from a crack in the towering rocks above, once viewed as having sinister origins, bestows another name on the area- Devil's Kitchen. The steam, however is actually the result of moist air coming into contact with the rock face, which forces it upwards, causing it to cool and condense, forming swirling clouds. Devil's Kitchen is known in Welsh as Twll Du, meaning black hole.
