Travellers consistently call this the best rainy-day option in Barcelona for families — particularly those with kids 3-12. Most-cited positives: the underwater tunnel, the Mediterranean tanks, and the location on the harbour. Most-cited issue: travellers without children find it less compelling than other Barcelona activities — it's primarily a family-focused attraction.
