SEA LIFE London Aquarium occupies the cavernous lower floors of County Hall, the grand former seat of London government on the South Bank, directly beside the London Eye and facing the Houses of Parliament across the Thames. One of the largest aquariums in Europe, it carries visitors below the waterline through a sequence of themed zones, culminating in a walk-through glass tunnel where sharks and rays glide overhead. For families, curious travellers and anyone seeking a rewarding hour or two indoors in the heart of central London, it is among the most accessible attractions on the river.
Why visit SEA LIFE London Aquarium
SEA LIFE London Aquarium is worth visiting for its scale, its central South Bank setting and its standout ocean tunnel, where sharks and rays pass directly above you. It offers a reliably engaging indoor experience for families and curious travellers, packing thousands of marine creatures into a single riverside venue beside the London Eye.
Its appeal lies in proximity and breadth. Few major attractions sit so squarely on the tourist trail, and fewer still gather such variety of marine life under one roof. The aquarium is arranged as a journey, moving from open displays of rays through coral environments to the deep ocean, so that even a fairly brief visit feels like a deliberate descent into the sea. Because it is entirely covered, it remains a dependable choice on a wet or cold London day, when much of the South Bank is best enjoyed from indoors.
Highlights and what to see
The aquarium is divided into themed zones, each built around a different marine habitat. The route is largely linear, guiding you from the shallows to the deep, with the most dramatic encounters saved for the journey through the main ocean display. Look out for the following highlights as you go.
- The Ocean Tunnel, a walk-through glass passage that lets you stand beneath sharks, rays and shoals of fish as they swim overhead.
- Sharks, among the venue's signature residents, viewed through the large ocean displays and the tunnel itself.
- Rays, often gliding close to the glass in their open tanks and a perennial favourite with younger visitors.
- Coral reef displays, vivid with tropical fish and a contrast to the cooler, deeper zones.
- Penguins, housed in their dedicated cold-water habitat.
- Jellyfish, lit dramatically against dark backdrops in their own gallery.
- Rockpool and touch experiences, where children can get close to smaller creatures under staff guidance.
Exhibits and feeding talks are refreshed from time to time, so it is worth checking the current programme before you arrive to make the most of any scheduled displays.
How to visit and getting there
SEA LIFE London Aquarium is located within County Hall on the South Bank, at the western end of Westminster Bridge and immediately beside the London Eye. The nearest Underground station is Waterloo, served by the Jubilee, Northern, Bakerloo and Waterloo and City lines, a short walk away. Westminster station, on the Jubilee, District and Circle lines, lies just across Westminster Bridge and is an equally convenient approach on foot, with fine views of the river along the way.
The aquarium is a popular attraction and tends to be busiest at weekends and during school holidays, so booking ahead is sensible. Tickets are usually cheaper and entry smoother when purchased online in advance, and timed-entry slots help to manage queues. Allow roughly an hour and a half to two hours for a full visit. As prices, opening hours and any seasonal closures change, please check the official SEA LIFE London Aquarium website for current tickets and times before you travel.
What's nearby
The aquarium sits at the heart of one of London's richest clusters of sights. The London Eye turns directly outside, while the riverside walk leads past street performers towards the cultural buildings of the Southbank Centre, the National Theatre and the BFI. Cross Westminster Bridge and you reach the Houses of Parliament, Big Ben and Westminster Abbey. A little further along the South Bank lie the Imperial War Museum and, downstream, the Tate Modern and Shakespeare's Globe. It is easy to fold a visit here into a broader day of riverside sightseeing.
