Loch Lomond is perhaps the best known of all the Scottish lochs - partly because of the song about it, partly because of its size and partly because it is so accessible (less than an hour's drive from Glasgow).
Loch Tay is in the heart of Perthshire. Like many of Scotland's lochs it is long and narrow - having been scoured out by glaciers in the Ice Age.
Loch Earn is mainly in Perthshire. It is a favourite place for sailing and watersports.
The romance of Loch Katrine was enhanced by Sir Walter Scott's "The Lady of the Lake". There is still a steam ship on the loch - oil-fired vessels are not allowed as Loch katrine is one of the main sources of water for the city of Glasgow, 30 miles away.
This picture of Loch Lomond was taken in winter time, after a light fall of snow.
Loch Lubnaig is a small loch in the Trossachs area of Stirlingshire, just north of Callander.
