Built between 1803-22, Neptune’s Staircase is a flight of eight locks on the Caledonian Canal. Set in the shadow of Britain’s highest mountain, Ben Nevis, it is the longest staircase lock flight in Scotland. This feat of engineering raises the canal by 62 feet (19 m) over a quarter of a mile (400 m) with continuous masonry and takes roughly 90 minutes for a boat to travel up or down.
This is the start (or end) of the Caledonian Canal which links the lochs of the great Glen with locks, and also part of the Great Glen Way walking and cycling route.
The flight of eight locks raise the water level on the Caledonian Canal by 62 feet (19 m), and takes boats approximately 90 minutes to navigate this short stretch. This is the longest flight of locks in Great Britain.
