 Grey Knotts is a "Wainwright" fell and also qualifies as a Nuttall, but this must be considered a borderline case, as it barely has the required 15 metres of prominence to the adjoining higher fell of Brandreth.All the highlights of Grey Knotts are situated on the eastern (Borrowdale) side of the fell, Raven Crag, known as Gillercombe Buttress to rock climbers.It is a popular area for bouldering, using the large number of large boulders that have become detached from the main crag.
