Overlooking the busy but beautiful Solent, Portsmouth’s Blue Reef Aquarium takes visitors on an undersea adventure.

From the rich variety of British waters to the beauty of a tropical coral reef and more than 40 other displays – the aquarium offers a fascinating window into the hidden world beneath the waves. At the aquarium’s heart is a giant tropical reef tank that is home to hundreds of brightly-coloured reef fish. Visitors are able to get up close to these creatures and see life from the sea bed, thanks to the underwater, walk-through tunnel.

During the summer, families can take a break in the outside play area and splash pool.
