One of the most dramatic prehistoric landscapes in Britain lies in Kilmartin Glen. Sharon Webb’s In the Footsteps of Kings (Kilmartin Museum, red. ed. 2013) provides some 25 walks to explore the glen’s heritage. This includes the burial mounds, standing stones, rock art as well as Carnassarie Castle and the Crinan Canal. And those looking for beavers in nearby Knapdale also have a suggested route. This is a beautifully produced book with clear maps and colour photographs. It is an essential purchase for getting the most out of this part of Scotland.
For other prehistoric landscape walks in Britain see Stonehenge and Avebury.

I have been there too and I read somewhere that there were a couple more “footprints” scattered in Scotland. Is that true ?
