The Central Fells are a group of hills in the English Lake District. Reaching their highest point at High Raise (2,500 ft or 762 metres), they occupy a broad area to the east of Borrowdale. Perhaps unexpectedly the Central Fells are generally lower than the surrounding hills, the Lake District's general dome-like structure having a slight dip in the middle. The range extends from the boggy ridge between Derwentwater and Thirlmere in the north, to the famous rock peaks of the Langdale Pikes in the south.
