My girlfriend and I were fortunate enough to be able to visit Norway in November 2013, and we both loved every minute of our time there. We had talked about doing a land-based trip but, in the end, we went with the Norwegian ferry company, Hurtigruten, as they had some very special prices on their 12-day round trip from Bergen to Kirkenes and back, as 2013 was the company's 125th Anniversary.
Describing Hurtigruten as just a ferry service, however is really underselling it, as the service we experienced would put some established cruise lines to shame. Hurtigruten operate 11 ships up and down the Norwegian coastline carrying passengers, mail and other cargo. Our 12-day trip stopped at 34 ports along the way - some of these stops were for as little as 15 minutes, though we were able to disembark in some of the larger towns and cities along the route, including Alesund, Trondheim, Bodo, Tromso, Hammerfest and Kirkenes.
Hurtigruten have a number of organised excursions in many of the ports that they visit including a trip to the North Cape and, our favourite, the husky sledding trip in Tromso. Also, as we were inside the Arctic Circle in November, we were lucky enough to see the Northern Lights three times during the trip - although it is quite difficult to take decent photos of the lights from a moving ship
We did find Norway to be an expensive country, however as the cost of accommodation and meals was included in the ferry fare, we only needed to worry about incidental expenses and souvenirs. If the cost and itinerary work out for you, I would recommend Hurtigruten as a way of seeing Norway, as the coastal voyage is truly breathtaking.
