2026 Glenarm Castle Tours
Step inside centuries of living history during the 2026 Castle Tour season at Glenarm Castle, the ancestral home of the McDonnell family, Earls of Antrim.
Still a cherished private residence of the Earl and Countess of Antrim and their family, Glenarm Castle opens its doors on select dates, offering visitors a rare and intimate glimpse into life behind its historic walls.
Guided by the family butler and house staff, your tour brings the castle’s stories vividly to life as you explore the elegant Drawing Room, grand Dining Room, atmospheric Blue Room, and the Castle’s striking Great Hall. Each space reveals generations of heritage, tradition, and personal history woven into the fabric of the castle.
From 17th March to 1st November*, complete your visit with a stroll through the enchanting 17th-century Walled Garden, a tranquil and beautifully restored space that adds another layer of discovery to your day.
Please note: Garden access is subject to ground and weather conditions. Discounted rates apply when the Walled Garden is unavailable, including during private garden bookings or the off-season (early November to mid-March).
Tours are limited and advance booking is essential.

Glenarm Castle is the ancestral home of the McDonnell family, Earls of Antrim.
The Castle was built by Randal McDonnell, 1st Earl of Antrim, in 1636 and it has remained in the family ever since. The McDonnells have been in Glenarm since the 14th Century and the story of the family is very interlinked with the history of the North Antrim Coast.
You can find out all about their story when you visit our Antrim McDonnell Antrim Heritage Centre. Today Glenarm Castle is the home of Randal and Aurora McDonnell, the 15th Earl & Countess of Antrim and their children.
Although Glenarm Castle is a private home, we are delighted to welcome visitors for guided tours on selected dates throughout the year. We also welcome group bookings for both Castle Tours and visits to the Walled Garden.
