It seems that every turn you make in Scotland, you run into a castle. Half are abandoned and the others have been brought back to glorious life. The very best of them are perched right upon beautiful waterways or lochs (lakes). Situated directly upon Loch Ness (Yes, THAT ness) is Urquhart Castle. I did not see any monsters, but Loch Ness is GORGEOUS and goes on and on and on -- a true "finger lake" if there ever was one. I always pictured Nessi's lake as some small pondish lake, but vast sea river might be a better descriptor. In any case, Urquhart has an ideal location and is a stunning ruin.
