Since opening to the public in 2005 the garden continues to evolve as a centre of horticultural excellence with imaginative herbaceous borders, water features, fruit and vergetable gardens and display of flowers which burst with colour from spring to autumn. From the mount at the top of the garden you have a great view of the Castle,sea and the estate beyond.

Glenarm Castle

Glenarm Castle is the home of Viscount and Viscountess Dunluce and their family. The present castle has been in the McDonnell family since it was first built in 1636. The McDonnells have been in Glenarm for nearly 600 years and the Estate has been in the family for 400 years. In the house you will see superb examples of Irish furniture as well as portraits of family members from the early 17th Century through to the present day. Before taking up full time residence at Glenarm the family lived most notably at Dunluce Castle. The castle is occasionally open to the public, and welcomes group visits. Contact us to arrange.

A warm welcoming awaits all visitors to the garden and on a few occasion ( the family open their home to visitors throughout the year.
