A compact harbour city where the aquarium, the funicular and a fjord boat sit within a mile.
Akvariet i Bergen
Penguins, seals and sea-lion feedings on a schedule worth planning around, out on the Nordnes headland with a playground and park attached.
VilVite science centre
Two floors of levers, bicycles and weather machines that reward pressing everything. Suits five to twelve, and it is entirely indoors when the rain sets in.
Fløibanen funicular
Eight minutes up the mountain to a viewpoint, a troll-themed forest trail and a large playground. Buy a single up and walk down if legs allow.
Mostraumen fjord cruise
Three hours from Zachariasbryggen through a narrow fjord to a tidal current and a waterfall. The boats are heated and enclosed, which matters here.
Rain is the plan
Bergen gets rain on most days of the year. Waterproofs and boots for everyone, and a mental list of indoor options, will save the week.
