Place to visit In Norway

 There are some things that are unique to Norway, I would search for those. Here are some examples:

Vigeland’s sculptures in Frogner Park Oslo

The Viking Ship Museum, the Fram, and Kontiki. All at Bygdøy in Oslo.

Very long road tunnels on the main roads to the west.

West coast fjords. In some places, the main road ends at the quay and you then take a ferry along the fjord to pick up the road again.

There is of course a lot more but that would keep you busy enough for a week or two. Try a road trip from Oslo to Bergen via Kongsberg and Hardanger, return via Sognefjord and Geilo.
