Dunadd - I once took my girls up to the top, the youngest one and I both took our shoes and socks off to put our bare foot into the carved footprint, the oldest (then fourteen) refused point blank. "Why not?", I asked. "Don't know who else has put their foot in it there" she replied with an indignant scowl.

I'm a Kilmartin addict. Personally, I think that the whole area is a Scottish equivalent of the Valley of the Kings - the atmosphere is very, very special. It just reeks of history and continuity - but you must stand on top of Dunadd - bare foot optional, but recommended!
