Midges - As Garlor said Avon 'Skin so Soft' is the stuff, no idea what chemicals they put in their cosmetics but it is the only thing that deters Scottish midges.

My favourite place in Northern Scotland is Skye -  everything is accesible and the island is a microcosm for the whole of Scotland in geological and topographic terms.  If ancient stone circles is what you are after there is one on the road to Elgol just behind the cemetry and chapel on the right.  Most people pass it without even knowing it is there. 
imho one of the best views in Scotland can be seen by following the path beside the chapel over the ridge for about 2miles, sign posted Camasunary, where you will see the the Cullins stretched out before you (if the weather is kind)  and views out over the western isles to Rum, Soay and beyond.
It is a steep path not to be attempted in bad weather !!!

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
