Ardgillan Castle and Demesne is a visitor attraction and community amenity situated in North County Dublin on an elevated coastline between Balbriggan and Skerries.

It's 32 kilometers north of Dublin City and only 20 minutes from Dublin airport. The demesne is well signposted off the M1. The park consists of 194 acres of rolling open grassland, mixed woodland and gardens, overlooking the Irish Sea with views of Mourne Mountains to the north and Lambay to the south-east. Ardgillan is a sanctuary for many species of animals, mammals and birds for which the wooded areas provide a safe retreat from surrounding agricultural land. Today the demesne is a stunning visitor attraction with a range of facilities the public can avail of, including castle tours, theatre events, afternoon tea, children’s parties, a dog-friendly café, fairy trail and much more!
