ZSL London Zoo’s BIG Summer of Fun!

What to expect from ZSL London Zoo’s BIG Summer of Fun!

Get set for heaps of family fun this summer with a whole day packed with wild games, over 14,000 animals, and giant attractions including England's biggest penguin pool, London’s biggest living rainforest and, of course, big cats.

New for 2023, from Saturday 22 July to Sunday 3 September there'll be no cheat-ahs allowed at the Really Wild Challenge: wildlife lovers can play their way through the animal kingdom with a whole host of animal-themed family games. Going head-to-head with their 'troop' to test their wild skills, families can try their hand at being a ZSL conservationist – working to protect wildlife across the world.

Whether you win big on the Really Wild Challenge or not, London Zoo is never short of super-sized experiences. Come face-to-face with a colony of Humboldt penguins as they dart and dive in England's biggest penguin pool, before saying hello to a newborn Golden lion tamarin in London's largest living rainforest. And don't forget to visit the zoo's big cats – Endangered Asiatic lions Bhanu and Arya, as well as Critically Endangered Sumatran tiger cubs, Zac and Crispin.

With more than 14,000 incredible animals to be inspired by, and free entry for under 3s, London Zoo's BIG Summer of Fun, running from 22 July to 3 September, is the ultimate big value day out this summer holidays.
