I know the foot bridge well. You park by Invergarry Post Office(it must be the smallest in the UK?) take a short walk to the bridge and there you are! Your, er, island? There are lovely walks along both sides of the river from almost top to bottom. Of interest just upstream of the dam on the right hand side is a rediscovered clearance village------long forgotten when trees were planted and only seen again when the trees were cut down a few years ago. I know there are all to many of these villages in the Highlands, but this one has been hidden away for the best part of 100 years. I am told that trees will not be replanted over the village and will be left for all to see. Makes me wonder how many more are lurking in those 100's of thousands of acres of trees that we have now.
