Cushendun Caves sit at the northern edge of Cushendun village, where the Glens of Antrim meet the sea on Northern Ireland's Causeway Coastal Route. They're small as sea caves go, carved into rust-red conglomerate rock that geologists date back roughly 400 million years, and you can walk the whole thing in under ten minutes. Most visitors aren't here for the geology, though. They're here because this is where Melisandre waded ashore in a rowboat with Davos Seaworth and gave birth to a shadow assassin in front of a fire, one of the stranger scenes from the early seasons of Game of Thrones. The caves hold up on their own merits too, with rock streaked in deep red and ochre, a sea that pushes right up to the cave mouth at high tide, and a crescent of cottages nearby that look lifted from the Cornish coast.

Why Cushendun Caves matter beyond Game of Thrones

The caves would be a footnote on most maps without the show, and that's worth saying plainly. There's no visitor centre here, no plaque, no gift shop cashing in on the association. What you get instead is an unmarked, free, publicly accessible sea cave that happens to have hosted one of the more talked-about moments in modern television, in a village that was never built for tourism the way the Giant's Causeway or Carrick-a-Rede were. That contrast, a genuine filming location with almost no infrastructure around it, is part of what makes the detour feel worthwhile.

Getting there

Cushendun sits on the A2 coast road, roughly midway along the Causeway Coastal Route, north of Cushendall and south of Ballycastle via the mountain road. From Belfast, the drive takes a little over an hour depending on which way you route through the Glens of Antrim. There's a small public car park right in the village, close to the river mouth, and the caves are a short, flat walk from there along the shoreline path, past the cottages and down onto the beach. You don't need a guide, a map, or any special equipment, just reasonable footwear.

The layout and experience

The caves open directly onto the beach, so the approach is simple: park, walk down past the Cushendun cottages, and follow the sand or rock shelf around to the cave mouths. There are a few separate openings rather than one single deep cavern, and you can walk into and through parts of the formation depending on the tide. The floor inside is often wet, sometimes with standing water, and the rock underfoot can be slick, so this isn't a place to wear anything with no grip.

Inside, the red conglomerate is the main event. It's a coarse, pebbly rock, visibly different from the darker basalt that dominates most of the Antrim coastline further north toward the Causeway. Light gets into the caves at an angle, so the mood shifts a lot depending on time of day and cloud cover. On an overcast afternoon the caves can feel flat and grey. When the sun is low and angled correctly, the red in the rock turns almost glowing.

History and background

The village of Cushendun is the other reason to linger here. Much of it, including the row of cottages nearest the caves, was designed in the early twentieth century by the Welsh architect Sir Clough Williams-Ellis, the same architect behind the far more famous Italianate village of Portmeirion in Wales. The connection isn't a coincidence of style, it's the same hand, and it's why Cushendun has a slightly displaced, storybook look that doesn't quite match the rest of the Glens. The cottages are now in the care of the National Trust.

The caves predate all of that by hundreds of millions of years, shaped by sea erosion working on sedimentary rock laid down long before Ireland had anything like its current coastline. None of that geology was on anyone's mind when the production crew picked this spot, but it's part of why the location reads so well on screen. Few coastal caves anywhere have quite that particular red color, which is probably why a location scout settled on this unremarkable stretch of Antrim coast for a scene that needed to look otherworldly without any set dressing at all. Within the show, the beach plays Dragonstone's shoreline, and the scene itself, Melisandre giving birth to the shadow that kills Renly Baratheon, is one of the moments that signalled early on how strange the series was willing to get.

Best time to visit

Tide matters more here than almost anywhere else on this stretch of coast. At high tide, parts of the cave floor can be underwater or difficult to reach, and the sea can come close enough to the entrances that lingering inside isn't sensible. Check a local tide table before you go, and aim for low or mid tide if you want to walk fully into the formations.

For light, late afternoon tends to work best in the warmer months, when the sun sits low enough in the sky to angle directly into the cave mouths and catch the red rock. Early morning in summer can work too, with fewer people around and softer light. Winter visits are possible and often very quiet, but daylight hours are short and the weather on this stretch of coast can turn quickly.

Photography tips

Bring something to protect a phone or camera from spray, since the cave floor is often wet and the sea isn't far off even at low tide. A wide lens helps capture the full mouth of the caves along with the red streaking in the rock, and shooting from just outside looking in tends to give better depth than standing inside looking out. If you're trying to recreate the look from the show, aim for the low, warm, late-in-the-day light rather than flat midday sun, which drains the color out of the conglomerate.

Facilities and preparation

There isn't much in the way of facilities at the caves themselves. No signage, no staff, no toilets on site. Cushendun village has a pub and a small shop within a few minutes' walk, which covers the basics. Wear shoes with grip, bring a layer for wind off the water, and don't count on mobile signal being strong right at the shoreline. Because the floor can be uneven and genuinely wet, this isn't an easy stop for anyone with limited mobility, and it's not somewhere to bring very young children without keeping a close eye on footing near the water's edge.

Combining with nearby attractions

Cushendun works well as one stop on a longer run along the Causeway Coastal Route rather than a destination in its own right. Cushendall, a few minutes south, has more in the way of cafes and shops if you need a proper break. Heading further north brings you toward Ballycastle and, eventually, the Giant's Causeway and Carrick-a-Rede rope bridge, both of which draw far bigger crowds and come with visitor centres, car parks, and entry fees. Cushendun offers the opposite experience: no infrastructure, no queue, and a sense that you've found something the main itinerary skipped over. If you're working through other Game of Thrones filming locations in the Glens and along the coast, this one slots in easily on the way between Belfast and the Causeway.

Practical tips

• Check tide times before you go, since high tide can block access to parts of the cave floor
• Wear shoes with real grip, the rock inside is often wet and can be slick
• Visit late afternoon in summer for the best light on the red conglomerate
• Park in the small village car park near the river mouth, it's a two-minute walk to the beach
• Don't rely on mobile signal right at the shoreline
• Pair the visit with a walk through the Clough Williams-Ellis cottages on your way down

FAQ

Is there an entry fee for Cushendun Caves?
No. The caves are open at all times with no ticket, booking, or staff presence.

Which Game of Thrones scene was filmed here?
This is where Melisandre, played by Carice van Houten, gives birth to the shadow assassin after arriving by boat with Davos Seaworth, a key early scene tied to the character Renly Baratheon's death.

How long does it take to see the caves?
Most people walk the full formation in under ten minutes, though many linger longer for photos or to explore the separate openings at low tide.

Can you visit at high tide?
You can still see the caves from outside, but parts of the floor can flood and the sea can push close to the entrances, so it's worth timing your visit around low or mid tide.

Is Cushendun Caves suitable for kids or wheelchair users?
Young children should be watched closely near the water's edge, and the uneven, often wet rock makes this a difficult stop for anyone with limited mobility.
