I might be slightly biased (
) but I think Norway is great for GA flyging.
The controllers are great
Bring up to date maps, and study the location of wires along your route. And have respect for the weather, lots of cumulus granitus when you get away from the Oslo area, and it often hides in cloud! Planning long flights in marginal VMC will more often than not end short of the destination....hopefully at an airfield.
