Dinas Cromlech
The great open book of the Llanberis Pass, its rectangular walls framing Cenotaph Corner, the most famous corner in the world. The concentration of historic hard routes on the two walls is unmatched: Brown, Whillans, Livesey and Fawcett all left their masterpieces here. South-facing and quick to come into condition for a Pass crag.

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.
