This aquarium is not huge, and if you just want to walk around the exhibits, you could do it in an hour or so. But they have tons of activities during the day, feeds, hands on experiences and the best one is the diver getting into the huge fish tank. For my kids, this all added up to the best day they had on the entire trip. there is only so much of fjords and mountains a kid can stare at, so this aquarium was the best antidote.
Gift shop is not bad either, good selection of soft toys, and surprisingly for Norway, you did not feel robbed.
Food in the cafe was overpriced rubbish, so beat a retreat and ate in town.
