About the garden

Owned by
Lord and Lady Antrim

Situated on the grounds of Glenarm Castle, The Walled Garden is one of the finest gardens in Northern Ireland. Dating from the early 19th century, in recent years it has been completely restored and includes new ornamental plantings by Catherine Fitzgerald as well as exciting new architectural and sculptural features. More recently 2022 saw the opening of a new woodland walk, with sweeping views across the park. 

With its incomparable setting by the sea, it will delight all with its charm and horticultural spectacle. Several delightful food outlets serve delicious offerings from breakfast through to afternoon tea. Several high-quality retail outlets are on offer too, selling plants, giftware, food and clothing.
