The Big One Hundred at Herstmonceux Castle

Our journey concludes at Herstmonceux Castle, against the incredible backdrop of a site steeped in over 500 years of history. We’ll be bringing a weekend-long Explorer Day to see out this incredible project. 

Across two days, experience the creature alongside a rich programme of performances, workshops and outdoor activity, offering young people one last chance to get collect their Explorer Stamps and become Ashdown Explorers, as well as a final opportunity to meet and interact with the curious creature.

Tickets for this event are included with standard admission to Herstmonceux Castle Estate and are priced according to Herstmonceux Castle entry rates. Tickets can be booked online via the Herstmonceux Castle website or purchased on arrival. As Herstmonceux Castle is often very busy during the summer and frequently reaches capacity in advance, we strongly recommend booking ahead.
