Snippets of our last Open Day


Harwell Open Day offers free admission; however, everyone must have a valid ticket to gain entry. It’s important to reserve a ticket for every individual over the age of 2 who plans to attend. Note that infants under 2 years old are not required to have their own ticket, but they must be accompanied by an adult who is a ticket holder.

We anticipate a high demand for tickets, and they are likely to sell out very quickly.

To ensure you don’t miss out on this opportunity, we strongly recommend booking your tickets as soon as possible.
