What you need to know

We've made some changes to help keep you safe, and things might be a little different when you visit. Here's everything you need to know.

  • Do we need to Book?

    You don’t need to book your ticket in advance, but you will always get the best price and guaranteed entry by booking online ahead of your visit.

    If you are a Member and wish to book, your ticket is still free.

    Your booking is for the site/event only and does not guarantee a car parking space, which may carry an additional charge.

  • Keeping you Safe

    Our staff are still working hard to keep everyone safe. We’re continuing with enhanced cleaning and you’ll find hand sanitiser stations on site. Our staff are continuing to wear a face covering in our busy areas and indoor spaces, and we encourage you to do the same. You can also help us keep you and other visitors safe by not visiting if you have symptoms or have been asked to self-isolate.
