Sea Life Helsinki

Sea Life Helsinki is an indoor aquarium next to Linnanmäki, displaying around 50 species of marine and freshwater life. Highlights include the glass shark tunnel, ray pool and a colourful tropical fish gallery. A visit typically takes 1–1.5 hours and pairs well with a trip to Linnanmäki, especially on rainy days. The route is short, indoor and fully stroller-accessible, making it suitable for toddlers and grandparents alike. Entry requires a ticket, available online or at the door. Parking is shared with Linnanmäki, with good public transport connections from the city centre.
