Falls of Dochart

Killin, Perthshire.
We are now in Pitlochry.
Despite the foreboding clouds we had a dry and very pleasant drive back through Glen Coe and along Loch Tay.
Along the roadside are great swathes of pink flowers. They appear to be either Rosebay willow herb or Himalayan balsam ( which Google tells me is also called Policeman’s helmet). . Or both.
