The Caledonian Canal in Scotland, built by engineer Thomas Telford in the 19th century, connects the east coast at Inverness to the west coast near Fort William. Stretching about 60 miles, the canal includes 29 locks, four aqueducts, and 10 bridges along its route through the Great Glen. With most of its length formed by natural lochs like Loch Ness and Loch Oich, the canal offers a scenic waterway for boats to navigate between the two coasts.
