SEA LIFE London Aquarium

About SEA LIFE London Aquarium

SEA LIFE London Aquarium sits in the basement of County Hall, the grand old building on the South Bank right next to the London Eye and directly across the river from the Houses of Parliament. It's one of central London's largest aquariums, laid out as a walk-through route that takes you down through a series of themed zones, from shark tanks and a glass-floored walkway to rays, seahorses, jellyfish, clownfish, and a penguin area. The Pacific display and the big ocean tank are the ones most people stop at longest, and the whole thing is designed to work for families with young children as much as for adults.

Because it's indoors and climate-controlled, it makes a good option for a wet or cold day, and it pairs naturally with other South Bank attractions since the London Eye, the Sea Life entrance, and the riverside walk are all within a couple of minutes of each other. Entry is by paid ticket, and timed-entry slots are the norm, so booking a specific arrival time online usually saves you queuing at the door. Weekends, school holidays, and midday hours are the busiest; earlier in the day tends to be calmer if you'd rather not navigate crowds around the smaller tanks.

Most visitors spend somewhere between an hour and 90 minutes walking the full route, though families with curious kids often linger longer. The venue is step-free and accessible throughout, with lifts between levels. If you're planning a full day on the South Bank, it's easy to combine with the London Eye, the Southbank Centre, and a walk along the Thames toward Westminster Bridge.
