Ais Gill Summit
Location : Mallerstang Valley, Garsdale
Ais Gill summit is the highest point on the Settle to Carlisle Railway, at 356 m (1,169 ft) above sea level. It is on the B6259 road, at the head of the Mallerstang Valley, just before the boundary between Cumbria and North Yorkshire.


Just north of the summit is the small Aisgill Viaduct, on the line as it passes along the side of the Mallerstang Valley from Kirkby Stephen.
Just south of the summit is the small Shotlock tunnel, Lunds Viaduct, Moorcock tunnel, Moorcock (Dandry Mire) Viaduct then Garsdale Station.


A few yards north of the summit is Hellgill Force, the highest waterfall on the River Eden, with a drop of about 9.75 metres.
Near here the River Eden’s source is hidden away, 2198 ft (670m) above sea level, in the moorlands above the Mallerstang Valley where two streams join to form Hell Gill Beck. After flowing over the spectacular Hellgill Force waterfall, the water then proceeds sedately as the River Eden down the Mallerstang valley towards Kirkby Stephen, roughly following the course of the railway.
