Overview
Carnlough sits at the head of a sheltered bay on the foothills of Glencoy, one of the nine glens that define the Antrim Coast and Glens. With a population of just over 1,500, the village retains a close-knit character while serving as a natural pit stop along the Causeway Coastal Route. The compact, limestone-built harbour forms the community’s centre, sheltering working fishing vessels, occasional pleasure craft, and a steady stream of visitors drawn by the dramatic coastal backdrop.
History & Heritage
The harbour’s design reflects the industrial ambitions of the mid-19th century. Local landowner Phil Gibbons commissioned its initial construction to service the extensive limestone quarries scattered across the surrounding hills. By the 1840s, the export trade had grown enough to warrant expansion under Frances Anne Vane Tempest, the Marchioness of Londonderry. She also funded the Harbourview Hotel in 1848 – originally opened as the Londonderry Arms coaching inn – which still anchors the village square today.
A quieter, deeply personal chapter of local history is carved into the harbour wall itself. A plaque here honours ‘Paddy the Pigeon’, an RAF messenger bird owned by a Carnlough native. During the Normandy landings in World War II, Paddy was one of thirty pigeons tasked with flying coded messages back to base. For his service, he was awarded the PDSA Dickin Medal, the animal equivalent of the Victoria Cross, making him the only Irish recipient of the honour.
What to See & Do
The Harbour Walk & Game of Thrones Steps
The most striking feature for visitors is the steep, stone-slated staircase that drops from the main street down to the water’s edge. These steps gained international recognition in Season 6 of Game of Thrones, standing in for the canals of Braavos as Arya Stark emerges from the water. Even without the TV connection, the descent offers excellent vantage points for photographing the harbour’s limestone arches and the 19th-century bridge that spans the entrance channel. For context on the area’s quarrying boom, the Heritage Hub inside Carnlough Town Hall displays local photographs and artefacts.
Boat Tours & Coastal Cruises
Local skipper Davy Smyth operates Carnlough Bay Boat Tours from the harbour aboard the Curiosity, a converted lifeboat run by a third-generation fishing family. The 30-minute Black Rock cruise (£10 for adults, £6 for children) is a popular half-hour excursion that circles the bay, offering reliable chances to spot bottlenose dolphins, grey seals, harbour porpoises, and colonies of seabirds.
Longer coastal trips extend north along the rugged shoreline. Routes typically reach Garron Point, Tommy’s Port, and Ringfad – the wreck site of the 1827 West Indiaman Enterprise of Lynn. The four-hour voyage to the Maidens islets includes a stop at a working lighthouse, providing a full-day coastal experience. Custom charters can be arranged directly with the operator for private groups.
Sea-Angling
For those interested in fishing, the Amberjack offers three-hour offshore trips departing about 1.5 miles from shore. Skipper Billy McClelland targets species like mackerel, cod, haddock, whiting, and gurnard. All equipment, including rods, bait, and a fish-finder, is provided, making it straightforward for beginners to join.
Getting There & Parking
Carnlough is located directly on the A2, which forms part of the Causeway Coastal Route. Ample free parking is available in the car park adjacent to the harbour, with spaces suitable for cars and small coaches. Clear signage from the A2 directs traffic straight to the village centre.
Public transport is available via regular Ulsterbus services running between Belfast and Ballycastle, with stops in Carnlough. Timetables and route numbers should be checked before travel, as services can vary on weekends and holidays.
Wildlife & Seasonal Highlights
The waters around Carnlough Bay are active year-round, but spring and early autumn typically offer the calmest conditions and the highest frequency of marine wildlife sightings. Grey seals are common residents, while bottlenose dolphins and harbour porpoises pass through regularly. Birdwatchers visiting between April and July may spot puffins, guillemots, and razorbills on the offshore rock stacks. Weather on the north-east coast can shift quickly, so layering up and bringing a waterproof jacket is advisable regardless of the season.
