About

The Big One Hundred concludes with a weekend of Explorer Days at the spectacular Herstmonceux Castle. Set within more than 500 years of history, this grand finale brings together performances and outdoor activities for the final chance to encounter the Forest’s mythical creature.

Young adventurers can collect their final Explorer Stamps and become official Ashdown Explorers while exploring the stunning castle grounds and gardens.

Tickets for this event are included within standard admission to Herstmonceux Castle.


Join us for The Big One Hundred: a brand-new programme inspired by the landscapes and wildlife of Ashdown Forest, to celebrate 100 years of Winnie-the-Pooh. Created in partnership with Ashdown Forest and award-winning creatives Trigger, the programme combines nature with storytelling and performance through a series of exciting events taking place across Wealden throughout the summer.
