Four of us went to Norway on a road trip on July. Was great fun!
There still is a ferry – a mainly freight affair leaving from Immingham and going to Stavanger – be warned though – it goes via Gothenburg so it's a 40 hour crossing all told.
Petrol is expensive but Diesel is cheaper than it is in Cambridge (although, having said that, it's probably cheaper on the Moon than Cambridge , too.)
We lined to floor of the car with beer and food. Seemed to work well and we only ate out twice I think.
There was only a little riding around Stavanger but there were some technical trails…
We moved on to Lillehammer and found the Hajfell Bike Park which was absolutely brilliant. Fantastic place, even if I did stuff my knee on one descent…
