Caledonian Canal

The Caledonian Canal in Scotland connects the Scottish east coast at Inverness with the west coast at Corpach near Fort William. It runs some 100 kilometres (62 miles) in a North-east to South-west direction. Only one third of the entire length is man-made, the rest being formed by Loch Dochfour, Loch Ness, Loch Oich, and Loch Lochy. These lochs are part of the Great Glen, a geological fault in the Earth's crust. There are 29 locks (including eight at Neptune's Staircase), four aqueducts and 10 bridges in the course of the canal.
