They need a Norwegian climber to come to the fore so we can get a proper mountainous race, I get the feeling the Tour of Norway is kind of a Tour of the Oslofjord to stay close to population centres, and the parcours is designed to maximise the reasons for people like Kristoff and EBH to show up.
They have stages finishing in Drammen, which is very close to Oslo, and they could have a 1-2 of puncheur climbs with Hagatjern before Drammen then a Murito finish at Landfalltjernet (I think they might have finished at Landfalltjernet the year they were 2.2 and Wilco Kelderman won, but not since going pro). I've been begging for a finish at Holmenkollen or Tryvann - plenty of room, the climb is enough to make a difference on a flat to hilly race but not enough to make it a one-stage race, and it's on the Oslo T-bane. And even as a Tour of the Oslofjord it sadly doesn't make the best of the sights, and that's hardly the most scenic part of Norway either (even though I absolutely love Oslo).
Anyway, you know what this race needs? It's finishing around Stavanger, just down the road from Sandnes, which hosts the Blink Festival, with its summer skiing and biathlon events. And that travels out a bit for a hillclimb race called the Lysebotn Opp. It's a ludicrously beautiful climb from a village in the Lysefjord.
Unfortunately, however, the village at the bottom simply cannot be connected to anything else; this is the only road out, and so involving it in a genuine race would be nigh on impossible... however, an MTT...
The Lysebotn Opp only climbs as far as Øygarstøl, so only just over 7km. That in my opinion is good, because it's steep, but short enough that the gaps won't be such that there can't be good racing on the other stages with a few hills here and there - it's not a "win the TT win the race" or "win the mountaintop win the race" event.
Edit: also, anybody interested in seeing Norway in its purest beauty could watch
this video. They famously broadcast the view from a Hurtigruten cruise ship, non-stop, and broke all kinds of viewing figure records in Norway. This video condenses it into one 37-minute chunk. I was in Norway at the time it was being broadcast, and can vouch for the hypnotic power of it. It was really nice after being out for an evening to come back in, chill out with a drink you hadn't had to pay a ludicrous amount for, and relax in front of some mesmerising scenery.
