According to Robin Reid, RSPB officer for the Western Isles, Bowglass (Bogha Glas) on the Isle of Harris is the best place in the whole of Europe to see Golden Eagles (BBC Wildlife, Feb 2015).
The track that goes up from [the car park at] Bowglass runs through four different golden eagle territories. If you spent a day between February and June going up that track…. there’s a good chance you’d see five to ten different eagles. I can’t think of anywhere else in Europe where you can walk up a glen and potentially see so many eagles in just three or four hours.
