Butterfly tunnel

Welcome to our butterfly tunnel – a tropical treat for all ages!

Come rain or shine, our tropical butterfly tunnel is a truly magical place to explore. Open from mid-May to October, it’s a warm, plant-filled haven where butterflies from around the world fly freely around you – and there’s something new to spot every time you visit!

A World of butterflies awaits

Step inside and you’ll find butterflies from South America, Africa, India, the Philippines and Australasia, flitting through colourful flowers and leafy greenery. It’s a peaceful, tropical space where the whole family can slow down and enjoy nature up close. 

See the butterfly life cycle in action

Our butterfly tunnel is not just beautiful – it’s full of fascinating things to learn.

You’ll see real pupae, carefully attached to sticks and placed in warm, steamy cabinets until they hatch. Once they’ve transformed into butterflies, we release them into the tunnel, where they can stretch their wings and start the next stage of their journey.

Look carefully under the leaves – you might spot tiny caterpillars or butterfly eggs! And be sure to watch your step… some butterflies like to rest on the ground.

Bright clothes? A butterfly might choose you!

Some butterflies are drawn to bright colours and even the salt on our skin. So don’t be surprised if one lands on your arm or shoulder! It’s a lovely moment – just be sure to check you’re not taking a butterfly home with you when you leave. They need to be in the butterfly tunnel to stay healthy and happy.

Why our butterfly tunnel isn’t open all year

We’re often asked why our butterfly tunnel is only open during warmer months. The answer is simple: our butterflies are from tropical parts of the world, and they need heat, humidity and sunlight to stay healthy – things we don’t have enough of in the colder months.

By opening from mid-May to October, we give the butterflies, and the tropical plants they love, the best conditions to thrive. During this time, you’ll see the tunnel at its absolute best – full of colour, movement and life.

It’s warm in there so take a break if you need to

The tunnel stays hot and humid to keep our butterflies and plants happy. Misters come on throughout the day to keep the air moist – just like a real rainforest! If it gets a bit too warm, feel free to step outside for a break and cool down.

Help us conserve British butterflies too

Feeling inspired? Every July, the charity Butterfly Conservation runs the Big Butterfly Count – a fun way to spot butterflies in your garden, local park or on a countryside walk. It’s easy to take part and helps scientists track how butterfly numbers are changing across the UK.

Sadly, more than three-quarters of British butterfly species are in decline. That’s why projects like this are so important.
