Carnlough sits where one of the nine Glens of Antrim meets the sea. The mountain road from Ballymena drops down through the trees, turns a corner, and the Irish Sea is suddenly there in front of you with a small white-walled harbour at the bottom of it. The whole village is built around that harbour, and the harbour was built around limestone.
Once, the hills behind the village were quarried hard. A narrow-gauge railway ran down from the quarries, over a stone bridge that still spans the main street, and out onto the pier where the boats waited. The trains are gone. The bridge is still there. So is the pier. Cross it on a calm evening and you can see why the production designers of Game of Thrones picked this spot to stand in for a canal in Braavos.
Most people pass through Carnlough on the way to somewhere bigger — Cushendall, the Giant's Causeway, the Glenariff waterfalls. That's the right way to travel this coast. But the village is worth a stop of its own: a coffee at the harbour, a slow look at the old hotel where Churchill once owned the rooms, half an hour up the path to Cranny Falls. Then back in the car and on round the coast.
Three things every local will eventually mention. Read these and you've already understood more than most day-trippers do.
Frances Anne Vane-Tempest, Marchioness of Londonderry, paid for the harbour in 1854 to ship limestone out by sea. The little harbour wall is still the prettiest thing on this coast.
Stories & lore → 02 The bridgeThe white limestone bridge that crosses the village road once carried quarry wagons down to the harbour. The trains are long gone. The bridge has stayed.
Walks → 03 The coast roadYou are on the Causeway Coastal Route. North to the Glens proper. South to Larne and the ferry. Either way, drive slowly — the road is the attraction.
Getting there →None of these are themed Irish pubs, because they don't need to be. A few that earn the trip:
The bar of the village's coaching-inn hotel. Open fires, dark wood, the kind of room where a long lunch turns into a long afternoon.
A proper village local on the main street. Pint, talk, no fuss.
Tucked beside the limestone railway bridge. The kind of place that's been there long enough that nobody remembers when it opened.
| Place | Type | € | Local note |
|---|---|---|---|
| The Londonderry Arms Hotel | Hotel restaurant | ££ | Lunch and dinner in the old coaching-inn dining room. Sunday carvery is the local fixture. Book for that. |
| The Waterfall Tearoom | Tearoom | £ | Soup, sandwiches, traybakes. The kind of café you want at the bottom of a walk. |

| The Londonderry Arms Hotel | Historic hotel | Built in 1848 as a coaching inn by the Marchioness of Londonderry. Winston Churchill inherited it from his great-grandmother in 1921 and briefly owned it. Still trading, still the social heart of the village. | |
| Self-catering cottages above the village | Self-catering | A handful of stone cottages on the slopes above the harbour. Wood stoves, sea views, the wind to put you to sleep. | |
The reason to come back. The things every local will eventually tell you about, usually after the second pint.
Wear waterproofs. Bring a sandwich. Tell someone where you're going if it's the mountain.
There is no bad time. There are different times.
Glens are at their greenest. Cranny Falls in full flow.
The Coastal Route is busy. Carnlough itself stays manageable. The harbour is at its best on a calm July evening.
The glen woods turn. Coach traffic thins. The hotel fires get lit.
Storms roll in off the Irish Sea. Some places shut midweek. The Londonderry Arms keeps going.
If a local was sitting beside you, this is the bit where they'd lean in.
You'll drive past Carnlough in eight minutes and remember nothing. Break the route at Carnlough or Cushendall. Stay a night. The whole point of this coast is slowness.
There isn't one. The harbour is the location. Walk to the steps, take your photo, move on. The official tours start in Belfast or Ballycastle.
Doesn't exist. The bridge is the museum. Stand under it, look up, that's the exhibit.
On the A2 Antrim Coast Road between Larne (30 min south) and Cushendall (20 min north). Belfast is 1h. From Ballymena, the B14 cuts over the hills and drops down through the trees into the village — it's the better arrival.
Translink Ulsterbus 162 runs Larne–Carnlough–Cushendall–Ballycastle along the coast. Useful for hopping a glen or two without driving.
Belfast International (BFS) is about 50 minutes by car. Belfast City (BHD) about 50 minutes too.
