Here is just a few places i'v visited in norway lately, that deserves a zone
All in the "Østlandet"-Region.
Tusenfryd - Norways biggest amusement park, South of Oslo. I placed a Suggestion outside the main entrence. http://www.tusenfryd.no
Oscarsborg on an Island, in the Oslo fjord, costs 90 Nok to take the ferry out there, But if you swim its fo free i guess
It's a Museum nowdays, And there are some real big cannons facing south, to Defend Oslo from the water. This place played a big role when the Nazis invaded Norway in 1940 and the sanked a big German Battleship. http://en.wikipedia.org/wiki/Oscarsborg_Fortress
Gaustatoppen Highest point in the region of Telemark, Alot of ppl walk up here. you can buy waffelt at the top station
Takes 2 houers to walk up but they say you can see one sixth of Norways mainland from the top. So I made a suggestion up there^^http://en.wikipedia.org/wiki/Gaustatoppen
There you go
Some real turistic zones^^
