A guided bike tour or bike rental is the perfect way to discover Oslo, one of the world's greenest cities. A bike takes you to all the places a bus cannot: along the beautifully preserved fjord coastline, among the trees and lakes in Europe's largest urban forest, next to rushing waterfalls in the downtown, through the old castle grounds and the Royal Palace Gardens or perhaps along the stunningly modern car-free harbor. Let Viking Biking show you all Oslo has to offer.
