Sea Life Brighton is a captivating underwater world located right on the seafront, just a stone’s throw from the iconic Palace Pier. It holds the prestigious title of being the oldest operating aquarium in the world, blending Victorian architectural grandeur with modern marine conservation.
What to See and Do
Visitors can walk through a stunning tropical ocean tunnel where sharks and giant sea turtles glide directly overhead. You’ll explore various zones, including the Day & Night exhibit, which mimics the shifting tides and bioluminescence of the ocean. There are interactive rock pools where you can touch a starfish, and a variety of tanks featuring everything from mesmerising jellyfish to camouflaged rays and colourful clownfish.
Length of Visit
On average, most visitors spend between 1.5 to 2 hours exploring the exhibits. If you take part in the extra experiences, like the glass-bottom boat tour, you might want to allow a little more time.


Who is it for?
Who might be bored? Those seeking high-octane thrills or massive, sprawling theme-park-style attractions may find it a bit intimate. However, the historical setting usually keeps even the skeptics engaged.
Best Time to Visit
To avoid the biggest crowds, aim for term-time weekdays or arrive right when they open in the morning. Late afternoons are also generally quieter. Since the attraction is entirely underground/indoors, it is the perfect “rainy day” activity in Brighton.
Unique Features
The architecture is the showstopper here. Unlike modern “box” aquariums, this centre is built into high-vaulted Victorian brick arches dating back to 1872. The contrast between the 19th-century design and the neon-lit modern tanks is something you won’t find anywhere else.
