There are four ways getting by car from southern Sweden (which is connected with the continental Europe by bridge) to the west of Norway, either around all of the Oslo Fjord and through Oslo, through the Oslo Fjord tunnel where the fjord is quite narrow, through the Bastøy ferries (I will maybe make a post on them later) just before the fjord meets Skagerak, and finally there is the outer ferry between Sandefjord and Strömstad. The latter trip takes around three hours one way, and there are three ferries going - two from Color Line and there is also a smaller company Fjord Line having one ferry. Here we met the Fjord Line ferry "Oslo Fjord".
Unfortunately the decoration on the bow got a bit in the shadow and is not much visible at the photos - it looks a bit impressive.
Not much visible, but in the distance there is another ferry coming the other way - a blue ferry from Color Line.
It's actually possible to take those ferries for free, the ferry companies are considering that they earn more on tax-free shopping on board than on the ticket fares. While I had my boat in Strömstad I took those ferries a couple of times. It's a bit counter-intuitive as the distance from Oslo to Strömstad is quite comparable with the distance from Oslo to Sandefjord. However, there are no direct trains from Oslo to Strömstad, one has to take a bus from Halden to Strömstad, and that journey is awful (local bus doing lots of silly detours and spending far too much time on the trip). Of course, from a time-perspective the direct journey is a lot faster, but one can enjoy the time much better in the restaurant in the ferry!
