Hi,
you could go up to Scotland and do some of the West Highland Way, especially the sections from Bridge of Orchy to Kinlochleven as these are the most scenic and the poor weather can often add to the atmosphere for taking photo's. There is also good accomodation available in bunkhouses at Bridge of Orchy and Kinlochleven and there is the famous Kingshouse inn in between.
Another good choice would be to go to some of the islands on the west coast of Scotland like Arran, Islay, Mull etc.. all beautiful places and there are reasonably regular bus routes round these islands that can leave you and pick you up in some very remote places.
If you need any info on these places, just ask.
Cheers John
