Dunluce Castle

Dramatic medieval castle ruins perched on basalt cliffs along the Causeway Coast, with a history spanning 1000 years. The partial collapse of the kitchen into the sea in 1639 adds to its romantic, windswept appeal and Game of Thrones filming connections. It sits in Belfast's City Centre, close to the other main sights. It sits below the headline sights but earns its place on a longer visit to Belfast, especially paired with nearby Carrick A Rede Rope Bridge. Tickets cost £5 adult, £3 child, family tickets available and 1-1.5 hours is enough to see everything without rushing.

You'll walk through crumbling stone archways with the Atlantic Ocean crashing directly below the cliff edge. The wind and isolation create an almost mystical atmosphere among the ancient walls.

Accessibility: Very limited wheelchair access due to uneven medieval stonework and cliff-top location

One of Ireland's most photographed ruins with strong coastal drama. It is not the first thing you should see in Belfast, but with two or more days it fills a gap the major sights leave. It pairs naturally with Carrick A Rede Rope Bridge and Peace Walls - together they fill a solid half-day. Afternoon tends to work best here.

Skip if: You prefer well-preserved buildings over distinctive ruins

• Wear sturdy shoes for uneven stone surfaces.
• Bring layers as it's very exposed to wind.
• Visit nearby Giant's Causeway on the same day.

Insider tip: The best viewpoint is actually from the coastal path below the castle, not from inside the ruins

handsome sunset shots possible, dramatic angles from cliff paths, some interior areas restricted for safety
