Main image

A freshwater loch in the Assynt area of Sutherland in the far north west of Scotland. It sits amid the rugged terrain of the Scottish Highlands.

Scenic shoreline and moorland views with walking routes and opportunities for wildlife watching rather than developed visitor infrastructure. The loch’s shore and surrounding hills are popular with walkers and landscape photographers.

The loch’s shoreline is dominated by the ruins of a historic castle that dates from the late medieval period and later centuries; the ruin is one of the most recognisable historic features on the loch.

Set in Assynt, Sutherland in the north west Highlands of Scotland, the loch lies within a remote, sparsely populated landscape of hills, moorland and freshwater bodies.

  • Best viewpoint: The ruined castle on the loch shore provides a classic photographic viewpoint, especially at low light.

What to See #

  • Ardvreck Castle: Ruins of a 16th-century stronghold stand on the loch's shoreline and are a well-known photographic subject.
