With all due respect for Stavanger - I love that town, but if you want the most amazing fjords and scenary, I would recommend
Geiranger further north- its on Unesco's World Heritage List. The fjords/scenary there iare all amazing post card material.
If you have a week, you have time for Geiranger AND Stavanger tho.
I would suggest you go straight from SCC to Oslo (45 minute drive), if you want some viking culture, the Viking ship museum is open until 6 pm on Sunday. Right next to that museum is the folk museum, a huge open air museum on Norwegian cultural history. Lots of exhibits and buildings, including traditional houses from the last 1000 years, including viking houses, a medieval
stave church up to a turn of the century town house - torn down and built up brick by brick. Close by is also the
Fram museum - a polar museum if you are interested in the polar explorers Fridtjof Nansen and Roald Amundsen and the
Kon Tiki/Thor Heyerdahl museumIf you are on a budget,
Coch's Pensjonat is the place to stay in Oslo- from 440 kroners for a single room (590 kr for their best rooms with fridge, kettle, bathroom and TV). It's a budget guesthouse smack in the middle of the best part of Oslo, located in Bogstadveien, the main shopping street on the West side. Right across the street is the Royal Castle, walk through the park for five minutes and you are downtown Oslo. If you want a standard hotel, there are lots of them for around 800-1000 kroners per night (shave off one zero and you have the price in £)
From Oslo you can drive directly north to Geiranger (425 km), experience the fjords etc (even the drive there should give you some good scenary). From Geiranger, drive south to the city
Bergen (370 km). The famous wharf/fish market in Bergen has been almost untouched since the 11th century (and on Unesco's World Heritage List too), visit composer Edvard Grieg's home or do a million other things you like.
From Bergen you can go to Stavanger - the oil industry capital (I am sure Trond can recommend lots of things to see/do there). I can promise you, the drive from Geiranger-Bergen-Stavanger will give you the most spectacular scenary/roads you will ever see.
From Stavanger you can get a ferry to the Northern tip of Denmark (you are returning to Belgium, right? If not, there are also ferries to the UK). When driving south through Denmark, I would recommend the beach on the west side where you can drive (and camp) right on the sandy beach.
