Crag Lough
Crag Lough is an inland lake at the southern edge of Northumberland National Park,
north of Bardon Mill, and north of the B6318 Military Road in Northumberland, northern England. At this point Hadrian's Wall is at the top of a line of crags, the Whin Sill, with Crag Lough at the foot of the crags.Etymology
The etymology of Crag Lough is linked to the Cumbric word luch, meaning 'lake'. The 'Crag' element is probably from a word equivalent to Welsh graig, 'cliff'.
