15 things to do in Brighton with kids
"The world’s oldest operating aquarium, it’s only a shell’s throw away from the sea itself with more than 150 creatures to see at the Brighton Sea Life Centre. Set in striking Victorian building, there are regular special exhibitions, as well as a variety of different underwater habitats, stamp trail, behind the scenes tour, and plenty more to discover including the UK’s first glass-bottom boat inside, activities for kids and the now obligatory underwater tunnel. The newest addition is the special Day and Night area showing how the oceans change over the course of 24 hours, including a bioluminescent beach."
