Loch Katrine - The Trossachs
Loch Katrine is a freshwater loch which is roughly 8 miles long by 2/3 of a mile wide and runs the length of Strath Gartney. It is a popular destination for tourists and day visitors from Glasgow and other nearby towns. The loch derives its name from the term cateran (from the Gaelic ceathairne, a collective word meaning "peasantry"). Historically this referred to a band of fighting men of a clan; hence the term applied to marauders or cattle-lifters, the most notorious of whom was Rob Roy MacGregor who was born at Glengyle House at the northern end of the Loch.
