I see that ejn is,

Off to Scotland in 11 days ...
back we go a week next Saturday to stay in a log cabin near Fort William ...
Thinking of going to the Isle of Mull and the Isle of Skye

I took a look at Google maps to get an idea of the overall location you will be visiting. 

One of my interests (and someday I will see some) is Standing Stones -- Neolithic Monumental Art/Architecture.  One of my references books is "A Guide to the Stone Circles of Britain, Ireland and Brittany" Second Edition (Paperback) by Aubrey Burl -- actually, I own the first edition ... but you'll want the later one.  The same book is also on amazon.co.uk [link]. 

If you are interested, I'll scan the map for that section of Scotland and list the site names from the book.  There are about 10 significant sites in and around that area.  OTOH, around Inverness, there are about 30 sites listed.
