Carrock Fell is a fell in the English Lake District, situated in the northern region of the national park 13 kilometres north east of Keswick. The fell's name means "Rocky Fell" and comes from a combination of the Old Welsh language with the word "carrec" meaning rock and the Old Norse language with fjall meaning fell.
The fell's altitude seems to have reduced by two metres in recent years, the Ordnance Survey now give it a height of 661 m (2,168 ft) in the most recent map updates after having recorded it at 663 metres for many years. Many guidebooks and mountain tables still record 663 metres as the “official” height.
Well known Lake District scribe Alfred Wainwright rated Carrock Fell as the second most exciting and interesting fell in the northern area of Lakeland (after Blencathra and before Skiddaw), it has special appeal regarding geology, mining and history and its rocky nature makes it stand out from the neighbouring fells which are mainly grassy and smooth.
