Day 1 — Oslo: arrival and a stroll along the Bjørvika waterfront
✈️ Upon arrival at Oslo Lufthavn Gardermoen airport, the most convenient option is to take the Flytoget express train to Oslo S (central station): about ~19–22 minutes, with frequent departures throughout the day. From the station, walk to the Bjørvika waterfront: the glass-and-wood Opera House, the wave-like Deichman Library building, and the brand-new MUNCH museum form a futuristic ensemble right by the water.
🚶 In the evening — an easy walk along Aker Brygge and Tjuvholmen: sea breeze, open terraces, yacht lights. If you want a more intimate vibe, head into the courtyards of the old center around Karl Johans gate.
