I am norwegian, and I confirm the fact that many of the norwegian resorts are park/big mountain-related. Though the real experiences don't come from our resorts. If you're into charging above the tree line, and prepared for some hiking, you will be pleased. Shit is fucking expensive up here (like 10 USD for a beer). If you've got the money, hire a boat for a week or two and hike the mountains around the fjords. Amazing nature.
Ask the guys on this norwegian forum if there's anything you wonder about. They're kinda like freeride/hiking gurus. http://www.friflyt.no/index.php?pagenr=32&zone=102&category=1000&subcategory=2
Norway has probably som of the best big-mountain skiing in the world. But the problem is that most of the ski resorts isn't build on the really big mountains. Off course you have places like Narvik, Hemsedal, Stranda and Røldal. But still if you wanna ski the best big mountains in norwa you will have to hike up, because heli's are not allowed to land on mountains in Norway without special permission. In the park scene we got really good places like Varingskollen, Hemsedal, hafjell and trysil. But compared to the US i don't think you will find the parks in Norway that good.
This is what i think of Norway after i started jibbing/ski pow 3 years ago.
