Dumbarton Rock
A brooding volcanic plug on the Clyde beneath Dumbarton Castle, and the crucible of Scottish hard climbing. Its glassy basalt boulders bred generations of crimp strength, while the main face holds Dave Cunningham and Dave MacLeod history: Requiem and Rhapsody, the world's first E11. Urban, graffitied and utterly iconic.

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.
