The festival returns in September with free entry available throughout the day. Various performers are present across the historic estate, alongside activities offered by heritage organisations, private owners and local authorities within the gardens. The event is funded and organised by Cadw as part of Wales' annual contribution to European Heritage Days.

Entry rules require no charge to attend, but the date is 19 September 2026 rather than Saturday 13 September mentioned in the text. The venue is Erddig Hall and Garden in Chester. Activities include exploring lesser-known and smaller-scale sites that are usually closed to the public.
