Clogwyn Du'r Arddu
'Cloggy' - the black cliff of Snowdon and the most revered mountain crag in Britain. Huge overlapping slabs and walls of perfect rhyolite hold a roll-call of historic routes from Colton and Brown through to Dawes's Indian Face, the first E9. North-facing and high, it needs a proper dry spell but repays the wait like nowhere else.

Freely-licensed photographs taken at or near the crag. Rock changes less than websites do, but check the date — an approach can silt up or a path can be diverted.
