Two smaller cities worth a stop: a medieval cathedral city and a town rebuilt in Art Nouveau after a fire.
Trondheim is Norway's third most populous municipality, with 218,460 people on 1 January 2026, founded in 997. Wikipedia says it was the capital of Norway through the Viking Age until 1217. Ålesund is a coastal town of 55,684 residents (2024), rebuilt in Art Nouveau after a fire on 23 January 1904.
We could not source a best season for either city from the pages we opened. See our when to go page for Norway-wide guidance.
Visit Norway: airport buses and trains reach Trondheim centre in 25 and 35 minutes, there are daily trains from Oslo and Bodø, the bus from Oslo takes about 8 hours, and Hurtigruten calls daily. Ålesund is a Hurtigruten port, according to Wikipedia.
A fire on 23 January 1904 destroyed much of the town, and it was rebuilt in that style.
Visit Norway says there are daily trains, and that the bus takes about 8 hours.
