We go to Norway every other year. If you want to be a tourist, most of the sites are well spelled out in guide books. I'm not saying that's bad, just not everything that is Norway. In Oslo see the Resistance Museum, Bygdøy, order hot food from cafeterias. Bergen is great, see old Bergen, Hanseatic Buildings, eat at or near the fish market, or in the basement of one of the many stores (locals eat there), Grieg's home Troldhaugen (old Bergen and Greig's can be seen on a single bus tour). Geiranger and Art Nouveau Ålesund are great, take a bus tour out of Ålesund to see high moutain passes, Geiranger by Ferry (ferry's are fun in Norway). Flåm train and "Nutshell" is ok but touristy. If you get a car in Bergen driving E16 will eventually get you to Oslo, but it will go through Flåm, near several Stavkirke and if you go on some side trips you can buy some great Norwegian Goat Cheese, fresh caught Mackerel, eat in some nice family/farm cafes buy some bringebær (raspberries) and see SogneFjord. It may take you 2/3/4 days but that’s some of the best of Norway. I just finished showing a friend how to spend 2 weeks in Norway and they will need to go back because there is much more. Trains are good but don’t get you into the smaller, quieter places, Bus service is wonderful. Cars and gas are expensive. Sunnfjord area has Glaciers and the best hiking (guides are available in many small towns and at some farms, ask when you eat in a cafe)
