It’s estimated that there are over 30,000 lochs in Scotland – from vast bodies of water to tiny lochans.
Their evocative names are known around the world, whether it’s the monster residing in Loch Ness or the famous oysters of Loch Fyne.
From attracting tourists in their droves, to providing a place to enjoy a range of recreational activities for generations of Scots, the country’s lochs are a key part of its magical geography.
Here are the 10 biggest in Scotland by surface area.

With a surface area of 71 square kilometres, Loch Lomond is by a significant distance the largest loch in Scotland but it has nearly a third of the volume of water of Loch Ness - just 2.6 cubic kilometres.
