Norway is incredibly beautiful, especially in the West Coast area and above the Arctic Circle. I especially liked going from Voss via the train from Myrdal to Flam down to the Sognefjord and then exploring by ferry and hiking.
The opportunities for hiking are unlimited, once you get established. The problem is trying to see everything, and also getting from point to point.
Norway is a very expensive place. Food, transportation, and lodging all induce sticker shock. But the Norwegians are some of the friendliest and most hospitable people I've ever met.
