ZSL London Zoo

Top choice in North London

Opened in 1828, London Zoo is the oldest in the world. The emphasis nowadays is firmly on conservation, breeding and education, with fewer animals and bigger enclosures. Highlights include Land of the Lions, Gorilla Kingdom, the walk-through In with the Lemurs, Night Life and Penguin Beach. There are regular feeding sessions and talks; various experiences are available, such as Keeper for a Day; and you can even spend the night in one of nine Gir Lion Lodge cabins.
