Salisbury Crags (Edinburgh)

 basalt, cliff, crag

The Salisbury Crags are a series of 150 foot cliffs at the top of a subsidiary spur of Arthur's Seat, here in the middle of Holyrood Park.
Below the foot of the cliffs is a large and steep talus slope falling to the floor of Holyrood Park with a track known as the Radical Road running in the space between the two. (This track is purported to have been given its name after it was paved in the aftermath of the Radical War of 1820, using the labor of unemployed weavers from the west of Scotland at the suggestion of Walter Scott.)
The cliffs are formed from steep dolerite and columnar basalt.
They have a long history of rock climbing on their faces starting from the earliest days of the sport and leading to a number of traditional climbing and sport climbing routes being recorded.
In recent years the Park Police have regulated access to the cliffs for climbing.
