SEA LIFE London Aquarium is an indoor aquarium on the South Bank, inside County Hall next to the London Eye, with sharks, rays, turtles, Gentoo penguins and jellyfish across 14 themed zones. Adult tickets cost from £28 online or £39 on the day (September 2026), and most visits take one to two hours.

The aquarium is run by Merlin Entertainments, the company behind the London Eye, Madame Tussauds and the London Dungeon. That matters for two reasons. Prices change with demand, like airline tickets, so the same visit can cost very different amounts. And you will be offered combination tickets with Merlin's other attractions, which can be good value or not, depending on what you actually want to see.

It is a walk-through experience spread over several floors of County Hall, entirely indoors, with lifts throughout. It suits families with children of primary school age best, and it is one of the more reliable rainy-day options in central London.

The zones you walk through

The route is one-way and takes you through a series of themed areas. SEA LIFE describes more than 500 species in 14 zones, and says it has the UK's largest coral reef display. In order, the main areas are:

There are six shark species, including sand tiger sharks, nurse sharks, blacktip reef sharks and a zebra shark. The sand tigers look fierce, with rows of pointed teeth, but the aquarium explains that divers regularly swim with them because they are not dangerous to people.

Talks and feeding times

Staff give short talks at Ray Lagoon, the shark displays, Rainforest Adventure and the penguins. They are the best way for children to learn something beyond the name on the label, and there are also feeding sessions and diving displays. The times change from day to day, so check the boards when you arrive and plan the route around the talk your children care about most.

Ticket prices and how they change

SEA LIFE uses demand-based pricing. The online price starts at the figures below and rises on busy days and as your date gets closer. The on-the-day price at the door is fixed and higher. SEA LIFE says advance online booking saves up to 28%, that there is no booking fee, and that the attraction is cashless, so bring a card.

TicketAdult onlineAdult on the dayWhat you get
StandardFrom £28£39Entry at a chosen time slot
Anytime EntryFrom £33£44Arrive at any time on your chosen day
Standard + VR ExperienceFrom £32£43Time slot plus a virtual reality ocean experience
Deluxe PackageFrom £38£49Anytime entry, VR experience and a mission pack or guidebook

Children aged 2-15 pay from £25 online or £35 on the day, and under-2s go free. Children aged 15 and under must be with an adult aged 18 or over. A free carer ticket can be added to an advance booking with at least one full-price ticket, with proof of eligibility shown on the day. Students can get discounted tickets through Student Beans.

What a family pays

Two adults and two children pay at least £106 online on a quiet day, and £148 if they turn up and pay at the door. A couple pays from £56 online or £78 on the day. That gap of more than £40 for a family is the main reason to book ahead, even if only the night before. Check live prices on the official ticket page.

Tickets are non-refundable, but you can change the date and time up to three times through the online booking portal, as long as there is space. SEA LIFE says it cannot guarantee entry to people who buy at the door, particularly at peak times.

SEA LIFE's "save up to" figures compare with door prices. A SEA LIFE and London Eye combination costs from £49 online. The aquarium says that saves up to £29, which is true against the two walk-up prices of £39 each. Against the two cheapest online prices, £28 and £29, the saving is closer to £8. The combination still helps, just by less than the headline suggests.

Combination tickets with the London Eye and other Merlin attractions

Because the London Eye, Madame Tussauds and the London Dungeon are run by the same company, SEA LIFE sells tickets that bundle them together. The published "from" prices in September 2026 were:

CombinationAdult online from
SEA LIFE + London Eye£49
SEA LIFE + Shrek's Adventure£49
SEA LIFE + London Eye + Madame Tussauds£54
SEA LIFE + London Eye + Madame Tussauds + London Dungeon + Shrek's Adventure£59

How they work: you book a time slot for SEA LIFE, which you visit first, and then have seven days to visit the others, according to the ticket page. You must book a free timed entry for each extra attraction through the booking portal, and entry is subject to availability, so book those slots early in busy periods. (A separate offers page on the same website mentions 90-day validity; check the terms shown when you buy.)

A combination ticket makes sense if you already planned to visit two or more of these attractions. Four or five paid attractions in one week is a lot of indoor time and money for most families, though, and a cheap bundle is not a bargain if you skip half of it. Our analysis of whether the London Pass is worth it explains how to compare passes and bundles with the tickets you will really use.

Merlin also sells annual passes covering SEA LIFE and many other attractions in the UK, which can pay off for residents or for visitors returning within a year.

How long to allow and when to go

SEA LIFE's FAQ says the average visit takes one to one and a half hours; the aquarium's main page suggests one and a half to two. In practice, families who stop for talks and the rockpool take the longer end, and adults on their own may be through in an hour.

The aquarium usually opens at 10am, with last entry an hour before closing. Closing time varies: in mid-September 2026 it closed at 5pm on a Friday and 7pm on a Saturday. Weekends and school holidays are the busiest times and the most expensive to book. A weekday morning in term time is calmer, cheaper and easier with small children.

The first toilets come straight after the Shark Walk. SEA LIFE has toilets with baby changing at three points on the route: after the glass shark floor, after Rainforest Adventure and just before Ocean Invaders. Once you move past one, the next may be a while away, so it pays to stop when you can.

Bags, buggies and accessibility

There is no cloakroom, and SEA LIFE does not allow suitcases or large items of hand luggage. Handbags and backpacks up to about 30 litres are accepted. If you are between hotels or heading to a train, find a left luggage service first; the aquarium itself points visitors to the London Eye ticket office or Waterloo station.

Buggies are welcome, and SEA LIFE says the attraction is fully accessible, with lifts throughout. There is also a free buggy bay if you would rather leave the pushchair during busy periods. Photography is allowed, but not with flash, because it can frighten the animals, and tripods are not permitted.

Visitors in wheelchairs or with other access needs will find detailed information in the aquarium's accessibility guide, linked from the official website.

Getting to County Hall

SEA LIFE is inside County Hall, the large building by the south end of Westminster Bridge that was once the headquarters of London's government. It is on the South Bank, beside the London Eye.

Buses on Westminster Bridge Road include the 12, 53, 59, 76, 148, 159, 211 and 341. Driving is not recommended: the aquarium is inside the Congestion Charge zone, and parking nearby is limited and expensive.

Is SEA LIFE London worth the price?

In its favour

  • indoor, compact and easy with buggies
  • sharks, penguins and turtles in one visit
  • next to the London Eye, so easy to fit into a South Bank day

Against it

  • expensive for one to two hours if you pay at the door
  • crowded at weekends and in school holidays
  • not as large as some of Europe's biggest aquariums

If budget matters more than sea creatures, London has excellent free alternatives for children. The Natural History Museum, with its dinosaurs and blue whale skeleton, costs nothing, and our guide to London's free museums lists more. For live animals on a larger scale, London Zoo is a full day out, at a higher price.

Making a day of it on the South Bank

The aquarium sits in one of the easiest parts of London for families. The London Eye is next door and the London Dungeon is in the same building. A river trip from the piers by the London Eye is a good way to rest tired legs; our page on Thames river cruises compares the options.
