North Norfolk Food and Drink Festival

Sixty-odd North Norfolk producers set up inside Holkham's walled garden — a proper working kitchen garden, not just a car park with gazebos — for a weekend of tastings, local cheese, seafood and drink stalls.

Free to walk in, which is rare for an estate this grand, and worth combining with a walk down to Holkham's beach or through the wider grounds while you're there.
