You can sail right through the heart of Highlands on a boat. The Caledonian Canal connects the Scottish east coast with the west coast. The canal was constructed in the early nineteenth century as a way to provide jobs for the displaced highlanders. The canal runs about 60 miles from Inverness to Fort William.
Only one third of the entire length is man-made, the rest is formed by a series of 29 natural lochs, four aqueducts and 10 draw bridges. Serval of which I stopped for while on my way from Inverness down to Oban.
The concept is simple, trap the boat and water into a chamber, then open one the doors on one end to let the water flow in. This process is repeated in a series to raise the boat up to the level of the next loch. Then the boat is free to sail until it reaches the next set of risers.
