Number 3: Sea Life London

SEA LIFE London Aquarium

Young visitors at the Penguin Point attraction at SEA LIFE London Aquarium

This is a great way to introduce the kids to the deep – which over 500 species of aquatic life on show.  You can see sharks and piranhas, as well as the more passive Nemo-like clown fish.  There are daily feeds and expert talks – fun whilst learning – the best of both worlds.
