The northern terminus of the Norwegian railway, Bodo is slightly north of the Arctic Circle (watch for the marker just before the train pulls into town). There's not much to do in town, although the modern cathedral is interesting and the Norwegian Aviation Museum is worth a look (http://www.
luftfart.museum.no). Nonetheless, the train trip there is a good way for Eurailpass holders to see a bit of tundra. Bodo is also very popular in summer—it's one of the largest towns in Norway that experiences the midnight sun (approximately 6 June-8 July). It also has a completely dark winter, should you want to get a taste of that. You can use Bodo as a jumping-off place for trips to the Lofoten Islands or for visiting the nearby Svartisen Glacier (excursions available on summer weekends only).
