>PS I presume it was a typo in your itinery when you said Callanish instead of Castlerigg on day one ;)

It was!

You guys have given me much food for thought. My heart is sinking a little with every post, as you are all saying the same.
I may be getting over-zealous with my trip. . (my original plans had me visiting Aberdeenshire on the way back to check the recumbent Stone Circles over there! I must have been mad!).

But how can I choose between Callanish & Brodgar?
