Visitors to the castle and garden will be transported into the magical world of Harry Potter while walking through the set of Hogwarts and the Poison Garden.
Activities in the garden include wand and spell-book making classes, the Forbidden Forest Trail of mythical creatures and a Muggles tour of the famous Poison Garden.
To coincide with the theme of Halloween, the garden will also host pumpkin carving lessons followed by a pumpkin parade.
CEO of the attractions Christian Perdier said: "Next month sees the final Harry Potter film his out screens. It’s an exciting time for us at Alnwick Castle with our famous reputation as a film location for Hogwarts and we wanted to bring the films to life for fans around the UK in a way only we can.
"The Castle will be a wizardry haven, from spells and magic, to tours of the castle grounds. It’s going to be the perfect place to spend a magical mid-term school break."
The events will run throughout each day in October, with a ‘Battleaxes to Broomsticks’ tour running daily from 11.30am to 2pm. Tickets for the finale Hogwartian Party on 28 October cost £20.
