|The Dervish Slab, Vivian Quarry, Llanberis Slate|
The Dervish level of Vivian Quarry consists of a compacted slab. The splitter crack of 'Comes the Devish' takes a line up the centre of the slab to overcome the overlap. 'Last Tango in Paris' takes the right-hand edge of the slab following a disjointed crackline to again eventually overcome the overlap. Enjoyable slab climbing leads to the top of both routes.
