The Eastern Fells are a group of hills in the English Lake District. Centred on Helvellyn they primarily comprise a north–south ridge running between Ullswater and Lakeland's Central Valley.
The Lake District is a National Park in the north west of the country and in addition to its lakes it contains a complex range of hills. These are locally known as fells and range from low hills to the highest ground in England. Hundreds of tops exist and many writers have attempted to draw up definitive lists of fells and divided the range into areas to aid their description.
The most influential of all such writers was Alfred Wainwright whose Pictorial Guide to the Lakeland Fells series has sold in excess of 2 million copies, being in print continuously since the first volume was published in 1952. Wainwright divided the fells into seven geographical areas, each surrounded by valleys and low passes. While any such division must be arbitrary and later writers have deviated to a greater or lesser extent from this blueprint, the sevenfold division remains the best known partitioning of the fells into 'sub ranges', each with its own characteristics. The Eastern Fells are one of these divisions, covered by volume 1 of Wainwright's work.
The Eastern Fells occupy the region between the A591 Keswick to Ambleside road and the lake of Ullswater to the west. The Helvellyn range forms the main spine of the group, running on a north–south axis and remaining above 2,000 ft throughout its length. To the south of the Helvellyn range, across the depression of Grisedale Hause, is the Fairfield group of fells. There are also a number of subsidiary ridges and outliers, particularly to the east of the main range. The eastern fells constitute the largest, if not necessarily the wildest, area of high ground within the district, its long sweeping ridges the perfect environment for long distance walking.
