Glenarm Castle overlooks an extensive demesne following the Glenarm River to the sea, providing a picturesque site. The present house was remodelled in the early 19th century, incorporating earlier versions of the mid-18th century and the early 17th century. The river valley was established as a deer park in the 17th century and developed as a landscape park from 1775. Nearer the house, features include lawns, parkland with mature trees, a lime tunnel, a beech walk and an arboretum. An early 19th-century gatehouse stands at the entrance to the demesne. There is a walled kitchen garden.
