"Is there any place in Norway that is unspoiled? "
Most of it. ^^
Especially way up north.
Okay, sir, as we all know, you are in Oslo; you are right there on the spot in Norway, the Nebraska of Europe.
This book recommends, among other things, "Kvikne's Hotel," in Balestrand, but it smacks highly of some sort of modern westernized trendy bed-and-breakfast, with those stupid quilts and all that.
And then it proceeds further north--all the way to the North Pole, as a matter of fact--naming places, and they all sound like tourist-traps and "artists' colonies," even as far north as Tromso.
Norway is a large country with a small population, and surely there are places where the Birkenstock-REI-Burden's Outdoor Outfitters-Ben & Jerry's ice-cream crowd do not go.
I am interested in going where they do not go.
