Glenarm Castle: An Inclusive Guide to the Antrim Coast’s Living Estate

Why Glenarm Castle belongs on your Northern Ireland itinerary

Glenarm Castle sits at the gateway to the Glens of Antrim on the famous Causeway Coastal Route, a scenic drive linking Belfast with the Giant’s Causeway. Part grand country house, part working estate, and part community hub, it blends history, horticulture, events, and coastal scenery in one easy stop for families, couples, and solo travellers.

Visitors come for the Walled Garden, woodland walks alive with birdsong, artisan food, and seasonal festivals. Many stay longer for sea-view glamping pods, coastal cycles, or to anchor a wider Antrim Coast road trip taking in Carrick-a-Rede Rope Bridge, Cushendun Caves, and the basalt drama of the Giant’s Causeway.

A short history of Glenarm Castle

The estate is the ancestral home of the McDonnell (MacDonnell) family, Earls of Antrim. The present castle was begun in the 17th century under Randal, 1st Earl of Antrim, and after periods of conflict and rebuilding, has remained the family seat ever since. Today, the castle remains a private residence with access by guided tour on selected dates, while the gardens and wider demesne welcome visitors much of the year.

The Walled Garden you see now took shape in the 1820s, when the castle’s household required a protected, productive plot near the sea. Over time, it has evolved into a richly planted, design-led space, balancing historic features with contemporary borders and sculpture.

Glenarm Castle: Highlights of the estate

The Walled Garden

Glenarm’s four-acre Walled Garden is a masterclass in coastal horticulture. Expect seasonal structure, yew hedging, brickwork, and espaliered fruit punctuated by exuberant borders from spring tulips to high-summer colour. Herb gardens, potager planting, orchards, sculpture, and a photogenic sundial keep your camera busy.

For families, the garden’s layout offers easy loops and benches for snack breaks. For couples, it’s an effortless amble with framed vistas. Solo travellers will relish the planting detail and tranquil corners for sketching or reading.

Woodland Walk

Enter at the top of the Walled Garden and follow gentle trails through mixed woodland. Look for red squirrels, robins, and views over parkland grazed by the estate’s shorthorn cattle. Footpaths are generally well-made, though some sections have gradients or uneven ground; sturdy shoes are recommended.

Castle tours (selected dates)

When available, pre-book a timed guided tour to step inside the family home. You’ll hear stories of the Earls of Antrim and see characterful rooms such as the hall and drawing room. For conservation and privacy, indoor photography is typically restricted; bring a small bag and be prepared for some standing and stairs.

Heritage Centre & Coach House Museum

Near the garden entrance, the Heritage Centre gives a brisk primer on the McDonnell family’s island-spanning story from medieval alliances to coastal estates. Petrolheads take note: the Coach House Museum often displays a rotating selection from Lord Antrim’s vintage car collection.

Food, drink, and artisan finds

• Tea Room (in the old Mushroom House): hearty soups, sandwiches, and bakes, with seasonal dishes championing estate produce such as Glenarm shorthorn beef and organic salmon.
• The Milk Parlour: freshly churned gelato – perfect post-walk.
• Pizza Pavilion: wood-fired sourdough slices in a sheltered space.
• The Potting Shed: hot drinks and traybakes beside the woodland walk.
• Retail: a cluster of makers and shops near the Welcome Centre for ceramics, scents, local crafts, and garden gifts.

Glenarm Castle: Planning your visit

Opening hours & tickets

In high season, the Walled Garden & Woodland Walk typically open daily around 10:00–17:00 with last entry 30–45 minutes before closing. The Tea Room often opens earlier for breakfast-style bites. Castle tours run on limited dates and must be booked in advance. Event tickets (e.g., Tulip Festival, Halloween/Christmas experiences) sell quickly.

Tip: if you plan repeat visits or will attend an event, consider a season membership, which can include perks such as early entry to the garden, event presales, and accommodation discounts on the estate pods.

Accessibility

There is step-free access to most outdoor areas and accessible toilets near the garden/Tea Room. Do note gravel car parks and paths in places, plus uneven historic surfaces. If you need assistance or a ramp for specific experiences, notify staff when booking teams are used to accommodating wheelchairs, mobility scooters, and buggies.

Photography

Photography is welcomed around the estate; however, indoor photos are usually not permitted during castle tours. Outdoors, be mindful of other visitors and any drone restrictions.

When to go

• Spring (Mar–May): tulips, blossom, and lengthening days. Chillier evenings; bring layers.
• Summer (Jun–Aug): long daylight, peak bloom, and the fullest event calendar, book parking and tickets early.
• Autumn (Sep–Oct): golden woodland and quieter paths; intermittent showers make waterproofs handy.
• Winter (Nov–Feb): limited opening beyond special events; atmospheric coastal light and value stays nearby.

Glenarm Castle: Getting there

By car: From Belfast, follow the M2 to Larne, then cruise the A2 Causeway Coastal Route north to Glenarm (about 35–50 miles / 60–80 minutes, traffic and photo stops depending). From the Giant’s Causeway or Ballycastle, wind south along the A2 through Cushendall and Carnlough (allow 60–90 minutes).

By public transport: Trains run from Belfast to Larne or Ballymena, with connecting Translink buses (service 162 along the coast) calling at Glenarm. Journey times vary (roughly 2–3 hours with changes). Timetables shift seasonally, so check live schedules before you travel.

Parking: Signposted estate parking sits above the village near the Welcome Centre. Arrive early on event days and bank holidays.

On two wheels: Hire an e-bike on site for a breezy spin to Carnlough Harbour (10 minutes) or along the coastal flats to Ballygally and Larne. Helmets and hi-vis are typically provided with rentals.

• With kids: Build your day around short bursts, garden first, snack stop, woodland loop, then Mini Land Rover or the dog-friendly Dog Park.
• With limited mobility: Start at the garden’s level paths and Tea Room terrace; ask staff about the easiest routes and any available ramps. Plan rest breaks on benches and inside the cafés.
• Photography: Golden hour paints the castle façade and garden walls; in spring, the tulip displays are irresistible. Respect no-photo zones indoors.

Beyond Glenarm: tie-ins across the UK & Ireland

Use Glenarm as your springboard for heritage-led trips around the UK.
