Crummock Water is a lake in the Lake District in Cumbria, North West England situated between Buttermere to the south and Loweswater to the north.
Crummock Water is 2.5 miles long, 0.75 mile wide and 140 feet deep. The meaning of ‘Crummock’ seems to be Crooked one. This may refer to the winding course of the River Cocker, which flows out of the lake, or refer to the bending nature of the lake itself. The lake is owned by the National Trust.
Today, I set off for a walk, up Rannerdale Knotts (355 metres). The climb to the top is quite strenuous, and will leave a lot of people with a red face – it certainly did with me!!
The fell overlooks the southern end of Crummock Water. In the late 11th century or early 12th century it is said that Rannerdale was the site of a battle between the native Cumbrians and Norsemen and the invading Normans. The battle is thought to have taken place in the side valley of Rannerdale, which runs east from the summit of Rannerdale Knotts, west of Whiteless Pike and south of Grasmoor fell. During May, the battleground is an abundance of bluebells, and is certainly worth a visit.
Rannerdale Knotts is often ascended from Buttermere, making use of the good path going up Whiteless Pike, before turning west north-west along Low Bank at the col at 950 feet. There is a more direct ascent up the west face of the fell from Hause Point at Rannerdale (the route I took), accessed from the B5289 road on the eastern shore of Crummock Water.
