Raven Crag is bordered to the west by the long valley of Shoulthwaite Gill, which is a tributary of the River Greta. To the north the ridge drops to a depression, crossed by the Keswick–

Ascents

The main face of the fell stands over Thirlmere Dam, and appears from there as a sheer crag, the higher fells behind being hidden by the ridge. Raven Crag is most commonly climbed from the dam, via a steep waymarked path through the forestry. This ends with made paths and some short sections of boardwalk. The ridge between Raven Crag and High Tove can also be gained from Armboth, or an ascent can be made from 'behind' via Shoulthwaite. This can include visits to The Benn and the earth ramparts of Castle Crag.Mark Richards: ''The Central Fells'': Collins (2003):

, partially screened by conifers. The view from the summit is limited by the trees, but the eastward panorama opens up from the brink of the crag itself and there is an aerial view of the Thirlmere dam. The reservoir is also seen end on to the south. The Benn and Castle Crag provide a close-up view of Raven Crag from the north.
