We are planning, for May 2010, a round trip drive from Oslo via Geilo, Bergen, Stavanger and Kristiansand. The only part that worries me is the drive from Bergen to Stavanger. Autoroute gives me a best route down the E39 but this seems to include about 3 ferries. Is this the best route and can anyone help with web links for ferry details. We have a full day for this drive so any suggestions for sights along the way to visit would be appreciated.
