Glen Etive is certainly a beautiful location and can bring all sorts of surprises for those willing to park the car and walk off the beaten track. This we did and followed one of the many streams coming down into the Glen. The crystal clear water provided an almost green hue through to the rocks below. I can confirm that the water was cold - very cold.
