Raven Crag is a fell
in the English
Lake District
. It acts as a superb vantage point for, and backdrop to, views across Thirlmere
reservoir.
is the high point on a 2 mile long spur running up the western shore of Thirlmere, branching off from the main ridge of the central fells just east of High Tove
. Subsidiary tops include The Benn (also known as Benn Man, 1,463 ft) and Castle Crag (1,381 ft), the site of an iron-age
settlement. The ridge has been extensively planted with conifers as part of the Thirlmere Forest, the face of Raven Crag appearing as a lone oasis of naked rock amid the trees.
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 500 ft 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.Summit and View
