Forego the lines by ordering tickets for Norled in advance. Make sure to take a jacket for the outdoor decks.
The ferry has a kids room on the lower deck. A great place for when you need a break from the wind.
To make the most of your trip to Bergen go during the warmer months of May-September, when the boat cruises operate.
Bring plenty of water and snacks for kids to avoid spending extra along the way.
