Clatteringshaws Dam

Highlight • Viewpoint

Striking dam that creates Clattringshaws Loch. You can't walk along the dam or get too close to the loch from here but it's a great structure to look at.

A lovely little place to unwind watching the otters bath and play around in the water.
There is also picnic tables, public toilets and a car park here making it an excellent overnight bikepacking location as well.

Nice way to cycle to the Big Water of Fleet Viaduct. Although one of the photo's, suggest there is some tarmac, we didn't found it. It's a really nice gravel …
