Hi Vix
I didn't really blog much of our Orcadian trip but this blog takes in some of the Hollywood sites.

Due to the now overcrowded nature of listings of Orcadian sites on here, it's hard to pick out the spectacular 'Hollywood' sites any more.

If you're on Mainland, the obviously ones are of course:
Brodgar, Stenness, MaesHowe and Skara Brae. All MUST-SEES for really good reason!

If you can get down to the Tomb of the Eagles you WILL have your mind blown :-)

Other easy 'interesting-but-less-well-known' ones are Wideford, Unstan, the Fairy Knowe. And Rennibister Earth House http://www.themodernantiquarian.com/site/5110/rennibister.html was superb.

There's no reason you shouldn't be able to see all those in 2 days.

If you can get to Skara Brae after official opening hours, you can see the place and have it to yourself without interruption from coach parties. We were there with Mr and Mrs Hob and it was absolute magic.

You may not need them as much as I did, what with me being a soft southern jessie, but don't forget your longjohns and a furry hat with flappydown ears suitable for polar exploration. And a flask of tea :-)

Have fun
J
