 and Derwentwater.

High Spy, the parent fell, forms part of the north-south ridge between Borrowdale and the Newlands Valley. The rough spur of Low Scawdel (1,709 ft) runs out due east from the summit, breaking steeply over Goat Crag and then falling to Broadslack Gill. This small tributary of the River Derwent separates High Spy from Castle Crag.

The wooded height of Castle Crag rises between Broadslack Gill and the Derwent, the two streams meeting to the north beneath the outlying knoll of Low Hows. It has steep faces on all sides except the south, where a low ridge runs out and then swings west around the head of Broadslack Gill. A narrow col

Summit and View

The summit area is believed to have been an ancient hill fort, although the western section has been sliced away by quarrying. It can only be gained by means of a sloping crack to the south.
