Oslo
Tucked into its own fjord and set at the water's edge, Norway's lively capital is a small and eminently walkable city with engaging mix of old and new, and graced by broad avenues, parks and elegant neo-classical buildings.
Don't miss the enticing shops of pedestrianised Karl Johansgate and Bogstadveien, medieval Akershus Castle, the eye-popping Vigeland Sculpture Park and Bygdoy Peninsula's Kon-Tiki and Viking Ship Museums.
