Seattle to Oslo, Norway from $463

🌍 About oslo

Oslo's signature move is free: walk straight up the sloping white-marble roof of the Opera House, right off the water, for a fjord view 22 metres up with no ticket and no set path. The other essential is Vigeland Park — 200-plus granite and bronze nudes by one sculptor, Gustav Vigeland, the largest such park by a single artist, also free. Eat brunost, the caramel-brown Norwegian whey cheese, and try smoked reindeer if you see it. Fair warning: Oslo is one of the world's priciest cities, so a beer can run £10 — a cheap fare here goes fast. Come June–July for white nights, when the sun barely sets and you can stroll the harbour at 10pm. Winter is dark and cold, but that's when the fares drop — a real trade-off, not a free lunch.
