The Crinan Canal is known as Britians most beautiful shortcut
The Crinan Canal starts at Ardrishaig on Loch Fyne, and ends nine miles away at Crinan on the Sound of Jura. It was designed to provide a quick link between the west coast and islands at one end and the Clyde Estuary at the other, and so avoid the long voyage around the south end of the Kintyre peninsula, which is featured in Paul McCartneys song Mull of Kyntyre.
In the nine miles from Ardrishaig to Crinan there are 15 locks and the canal reaches a height of 65 feet above sea level. The summit reach of the canal is relatively short and every time a boat goes through the locks about 300,000 litres of water are used. No fewer than seven reservoirs feed the summit to ensure that the Canal does not run dry.
