We can guarantee you’ll encounter some of the rarest animals on the planet.
We can guarantee your visit funds our vital species-saving conservation work.
We can guarantee a great day out.
But the one thing we can’t guarantee? The weather! Until now…

Our new Rainy Day Guarantee is here to help make sure you get a fantastic day out, even if the weather isn’t very good.

If it rains continuously for over an hour then you can come back and visit us for free on another day.

This means that you can enjoy great online savings without having to worry about the weather on your chosen date!


Our rainy day guarantee is simple. If you’ve booked online and it rains persistently for more than an hour during your visit, we’ll send you an email explaining how you can return again on a different day, free of charge. You’ll just need to keep hold of your original ticket which will still be valid for your rainy day replacement.


There’s still plenty of exciting things to do at the zoo when it rains. You can explore our immersive indoor spaces – like Monsoon Forest and Tropical Realm. Or why not discover our digital exhibit Planet Shark which opened earlier this year. Our animals also enjoy all weathers so a rainy day can still be a fun one, just don’t forget the waterproofs! Discover some of the wondrous places you can enjoy in all weathers at the zoo:
