Anyone ever fly fished in Norway?

There's not a ton of information out there, but from what I can find there don't appear to be too many restrictions. Are there any weird regulations that I'm unaware of? The biggest issue seems to be getting access. How difficult is access to river fishing?

How about fishing from the beaches/fjords? I know you don't even need a license to fish there, but I'm just curious how easy it is to successfully fish these places.
