Loch Lomond stretches 22 miles and straddles the Highland fault which separates the Scottish Highlands from Lowlands.
By the way, the famous song "The Bonnie, Bonnie Banks of Loch
Lomond", which is known the world over is said to have been
composed by a follower of Bonnie Prince Charlie (a Jacobite), on the eve of his
execution in Carlisle Jail. The "low road" is the way in which his
spirit will return home quicker than his friend’s "high road".
