An aquarium is set to open a special immersive underwater trail in time for Halloween.

The Sea Life centre in Marine Parade will launch the “Ascarium” trail on October 20, inviting guests to find magic potion ingredients hidden in the tanks of some of the centre’s scariest sea creatures.

With these ingredients located, visitors must then enter the lair of the terrifying Sea Witch, whose magic spell will open a treasure chest containing a special prize.

Each paying guest will also receive a free return voucher for the Spring of 2019 to experience a brand new ocean display currently being restored.

The Aquarium is also running a competition in which one family can win a trip to Alton Towers.

The attraction will run until November 4 and entry starts from £11.50 when bought online.
