Of all the myriad excursions organized by fjordland tour operators, the most trumpeted is the whistle-stop Norway in a Nutshell, which can be booked at any tourist office in the region or online at wnorwaynutshell.com. There are several possible itineraries to choose from, but the classic round trip from Bergen takes eight and a half hours, and is an exhausting but exhilarating romp that gives you a taste of the fjords in one day. The tour begins with a train ride to Voss and Myrdal, where you change for the dramatic Flåmsbana branch line down to Flåm. Here, a two-hour cruise heads along the Aurlandsfjord and then the Nærøyfjord to Gudvangen, where you get a bus back to Voss, and the train again to Bergen. You can pick up the tour (and shave an hour and a half off) in Voss for an affordable 705kr: the full excursion from Bergen costs 1045kr.
