The fell reaches a height of 699 metres (2,293 feet) at the northern end of its summit ridge and this is the accepted highest point which gives the best views, although there is a spot height of 710 metres (2,329 feet) less than a kilometre to the south. Both tops have small cairns set on grass. Gray Crag is located in the far eastern sector of the national park, five kilometres south east of the village of Patterdale, and is basically the narrow grassy northern ridge of the adjoining fell of Thornthwaite Crag. It is characterised by very steep flanks with crags and gullies which fall away towards Hayeswater on the eastern side and Pasture Beck to the west. This fell should not be confused with Grey Crag another Lakeland Fell also in the far eastern sector above Longsleddale.
