The London Sea Life Aquarium is one of the largest in Europe and, with its new owner and branding, has got even better. Fish and other creatures from the briny deep are grouped in some 15 zones according to their geographic origin, from the Pacific to the Atlantic Oceans and from temperate waters to tropical seas. The coral caves (zone 8) and tropical rainforest (zone 10) displays are particularly impressive, and there’s a shark walkway at the end. Things get localised with The River Thames Story (zone 11).
