This is the Falls of Acharn near Kenmore on Loch Tay Scotland.
Taken from a narrow wooden footbridge which crosses the stream. A difficult spot to compose from just setting up the tripod was tricky. Still nobody said it was going to be easy. I was under strict instructions not to climb over the side of the bridge by you know who!
