Hi Tom, I'm up the week after you, can't wait.
As people say, Kintyre is a treasure chest of beautiful views. I would personally recommend:-
* Skipness. Go for a walk round the Castle and Abbey, at this time of year it will be deserted, just you and the elements, and the proxinmity to Arran leaves loads of opportunities for great photos.
* Saddell Bay. Just my favorite place on Kintyre. Extremely serene vibe, and the lovely Landmark trust properties (including the castle) around the bay, make for great dusk shots. Especially when the candles are flickering from within!
* Westport Beach. Especially on a clear day, some nice shots of the Paps of Jura can be had.
Best bet is to take a look at the pics on here, or look at some of the views in my latest video (Back To) The Kintyre Way, here ...
