Get your family and friends together for a huge celebration at the UK's largest Zoo.

Join us for the Big Birthday Bash over the May bank holiday weekend (2-4 May 2026).

We're marking 200 years of ZSL - the charity behind Whipsnade and our sister site, London Zoo. And to celebrate this momentous milestone, we're throwing a family-friendly street party with crafts, games and a gigantic picnic.
