Discover garden delights
A gentle springtime walk with your mum or little one through 100-acres of beautiful gardens is the perfect way relax and unwind. Admire bright spring colours as daffodils and crocuses emerge from the winter as part of our Bulbs and Blooms planting. Then treat yourself or your mum to a delicious drink and cake, or indulge in a Mothering Sunday lunch from the café. You can also enjoy family festivities for St Patrick's Day on Sunday 15 March.
Explore the castle
For just half the price, on Sunday 15 March join our expert castle hosts to uncover the history of Hillsborough Castle. Experience the grandeur of the State Rooms, discover stories of celebration and learn the pivotal role of Hillsborough Castle in the Good Friday Agreement negotiations. You will also experience Royal Style in the Making, an exhibition that explores the bond between the fashion industry and British royal women.
