Idwal Slabs
The great grey sweep of slabs above Llyn Idwal in Cwm Idwal, where generations of British climbers have learned their trade. Long, easy-angled padding up water-worn volcanic rock, with the harder walls above holding pre-war test-pieces like Suicide Wall. Drainage lines mean the slabs stay greasy for a while after rain.

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.
