One day
Start in the centre before the cruise crowds and walk the Art Nouveau streets around the Brosundet canal — Kongens gate, the decorated facades, the warehouses on the water — and step into the Jugendstilsenteret to make sense of it. Climb the 418 steps up Mount Aksla to Fjellstua for the panorama, then come down for a harbour seafood lunch. Spend the afternoon at the Atlanterhavsparken aquarium west of town, and end with a bacalao dinner in a warehouse restaurant on the canal.
