SEA LIFE Brighton: how to do it well
The world's oldest operating aquarium sits on Marine Parade, and a little planning makes it a much better wet-weather morning.
By Only Brighton Editorial
SEA LIFE Brighton is on Marine Parade, BN2 1TB, next to Brighton Pier on the Seafront. It has been there since 1872, which makes it one of the more unlikely things you can do on a rainy Thursday: walk through a Victorian arcade and end up under a shark. It is an all-weather attraction, so it earns its keep when the seafront turns grey.
A bit of history
The aquarium was conceived and designed by Eugenius Birch, the architect of the West Pier. Work began in 1869 and it opened in 1872, at a cost of £133,000, which the official history puts at about £5.5 million today. Guinness World Records lists Brighton as the world's oldest aquarium still in operation.
It had a rocky financial life. The Corporation bought it in 1901 and rebuilt the exterior between 1927 and 1929, though it was still regarded as a white elephant. It was requisitioned by the RAF during the war, ran as Brighton Aquarium and Dolphinarium from 1969 to 1991, and SEA LIFE bought it in 1991. A £2.7m Day and Night display opened in May 2019.
Look up as you go in. The Victorian arcade at the entrance has Gothic and Pompeian-inspired arches and columns, with coloured lighting. It is the best bit of architecture you will walk through all day.
What to see
The official site says there are more than 5,000 marine creatures, from rays and sharks to seahorses, starfish and an iguana. The zones are Day and Night, Glass Bottom Boat and Rainforest Adventure. The walk-through ocean tunnel is the showstopper, and the seahorse nursery is worth slowing down for.
The green sea turtles, Lulu and Gulliver, are the residents to find. Lulu is the biggest at 28 stone, and both are around 80 years old.
The glass bottom boat is billed as the UK's first indoor glass-bottomed boat, floating over the 750,000-litre Ocean Display. It costs extra, so check the price when you book. Brighton Journal gave the aquarium five stars in March 2026, praising the themed zones, the tunnel, the boat and the staff talks, and called it not the largest aquarium but packed with character.
To be fair, some recent TripAdvisor reviewers call it dated, say a few tanks could do with a refresh, and found the walkthrough shorter than expected. Allow 1.5 to 2 hours; the ticket is valid all day.
Tickets and booking
Book online before you go. The official site says it is essential to guarantee entry, and it is a cashless attraction. Advance adult tickets start from roughly £16 to £19 depending on the page and the day, and they cost more on the day. Prices change, so check the official page for the date you want. The official tickets page is the one to trust.
- Under 2s go free, according to the official site.
- Compass Card holders pay the standard rate, and one accompanying carer goes free.
- A ticket-holding disabled guest can get a free carer ticket with documentation.
- Thameslink promotes a discounted attraction offer for rail travellers.
When to go
Visit Brighton says it opens at 10am, with closing times varying through the year. Winter hours are shorter, and autumn hours on the official site have shown last entry as early as 2pm or 3pm. Check the day before you set off. A reviewer on TripAdvisor suggested booking the opening slot, finding it quiet first thing and busy by the time they left. A weekday morning, pre-booked, is the sensible plan.
Getting there
From Brighton station it is about 20 minutes on foot: down Queens Road to the seafront, then turn left. Buses 12, 12A and 27 stop outside. Official advice is to come by train, as council parking is limited and can be expensive. Coach parking is on Madeira Drive.
The aquarium is buggy and wheelchair accessible, apart from the auditorium Ocean Display, which can be seen from the Ocean Tunnel. There is an accessible toilet and a buggy park. For the step-free entrance, go from the promenade onto the seafront, take the ramp to the beach, then use the underpass to the entrance. The official directions page has the detail.
For after: Shelter Hall
Shelter Hall is at Kings Road Arches, BN1 1NB, a walk of roughly 15 minutes west along the seafront. It is a food hall in a building from the 1880s, with seven kitchens, a bar, a terrace and the Skylark cocktail bar, open daily until late.
Restaurants Brighton mentions breakfast rolls and hash browns from 3Bros Burgers, Portuguese-style broken eggs from Churrasco, and chicken and waffles from Lost Boys Chicken. Pick one, find a seat on the terrace if the weather allows, and let the turtles settle in your head. More at Visit Brighton.
