You leave Belfast on the M2 with the shipyard cranes fading in the rear-view mirror, and within forty minutes the city is gone. That is the thing about the Causeway Coastal Route — it does not really begin where the brochures say it begins. It begins the moment the motorway ends and the water starts appearing on your right. From there to the Giant's Causeway you have roughly fifty miles of coast, and every one of them earns its place.
Most people talk about the Causeway Coastal Route as one continuous ribbon from Belfast to Derry. It is, technically. But the eastern half — Belfast to the Giant's Causeway — is a different creature from the western stretch. The western half has the distilleries, the rope bridge, the castle ruins and the big-sky beaches. The eastern half has the Glens, the fishing villages, and the road itself, which is the main event. If you try to do the whole thing in a day, you will remember the traffic and the car park queues, not the places in between. Give Belfast to the Giant's Causeway a full day, and you will understand why this drive keeps showing up on lists. The full route is covered in our complete Causeway Coastal Route hub, but this guide is about the eastern half and how to do it properly.
The Eastern Half Deserves Its Own Day
The eastern half of the Causeway Coastal Route gets treated like a commute. People drive it because they have to, on the way to the Giant's Causeway, and they treat the stones as the only destination. That is the wrong way round. The stones are the full stop at the end of a very long sentence, and the sentence is the road.
Start in Belfast and you have the whole day in front of you. Start in Larne and you have already cut off one of the most interesting transitions in Irish driving, which is the move from city to coast in under an hour. Start at the Giant's Causeway and drive east, and you are fighting the sun and the afternoon coaches all the way. Belfast to west is the natural direction, and the one I recommend.
This half of the route also suits the kind of traveller who likes a bit of everything in one day: harbours, gardens, beaches, cliffs, villages and one world-famous geological oddity. It is not a theme-park day. It is a driving day, and the car is what makes it possible.
Belfast to Larne: The Quiet Start Most People Rush
The first section is the one drivers skip. They want the cliffs. But Belfast to Larne has its own story, and rushing it is a mistake. You pass through Carrickfergus, and if you are early enough, the castle is worth a stop — not a long one, but the keep and the views across Belfast Lough are solid. It opens at ten most days, and the morning light on the water is worth the timing.
Beyond Carrickfergus the road tightens and the hedgerows close in. You are still on the A2, but it feels smaller now. Larne itself is a working port, not a picture-postcard town, but it is a good place to fill the tank and buy coffee before the real coast begins. Petrol is cheaper here than it is at the Causeway visitor centre, and the supermarkets have proper sandwich selection. There is no shame in getting fuel and leaving. The coast starts just past Larne, at Glenarm, and once it starts you will not want to stop.
The Antrim Coast Road Proper Opens Up
Once the A2 turns coastal at Glenarm, everything changes. The road hugs the shore, the Mourne Mountains sit across the water to the south, and you are driving through a landscape that feels older than the maps. The section from Glenarm to Cushendun is what people mean when they say the Antrim Coast Road. It is not the only beautiful part of the route, but it is the part that teaches you the rhythm of this drive: slow corner, open view, slow corner, open view.
Glenarm has a walled garden and a castle estate that opens on certain days. Carnlough, a few miles on, has a small harbour where the local fishermen still unload. You can stop for tea and watch the boats. Waterfoot sits at the foot of Glenariff, the Queen of the Glens, and if you have time the short walk up the Glenariff Forest Park waterfall trail is one of the best quick stops on the whole coast. We covered the best of this stretch in our
We covered the best of this stretch in our Antrim Coast Road driving guide, and I will not repeat it all here. The short version is this: do not rush it.
Cushendun, Cushendall and the Glens of Antrim
Cushendun is the first village that makes you want to stop. White cottages, a small harbour, and a beach that empties out as soon as the coach buses leave. It is a good place for a walk and a sandwich. There is a reason artists and writers have been coming here for a century: the light is different. The harbour curves in a way that calms the water even when the sea beyond it is rough.
Cushendall, a few miles west, is larger and more practical — shops, pubs, and a straight run of seafront. It is also where the road starts to feel wilder. Between them you are driving through the Glens of Antrim, nine glens that cut down from the Antrim Plateau to the sea. You do not need to name them all. You just need to know that the road dips into green tunnels and then opens again to the water, over and over, and that this is the reason you came.
Torr Head and the Secret Shortcut
Just past Cushendall, the main A2 cuts inland slightly. The scenic option is the Torr Head Road, a narrow single-track that climbs and drops along the headland. On a clear day you can see Scotland. On a busy day you will meet a tour bus coming the other way and discover exactly how wide your car is. There are passing places, but they are not always where you want them.
I like the Torr Head Road, but I do not recommend it to cousins who are still getting used to the left side, or to anyone in a hurry. It adds time. It also adds views. If the weather is good and your nerves are steady, take it. Otherwise stay on the A2 and do not feel guilty. The main road is still beautiful. The point of this drive is not to take every shortcut.
Ballycastle: Lunch, Fuel and the Ferry Decision
Ballycastle is the last proper town before the Giant's Causeway, and it knows it. The harbour is busy, the chip shops are good, and there is a real choice of places to eat. It is also the jumping-off point for Rathlin Island. The ferry runs from here, and in summer it books up. If Rathlin is on your list, you need to decide that in Ballycastle, not when you reach the car park.
For most cousins doing this drive, Ballycastle is a lunch stop and a fuel stop. That is enough. Do not linger so long that you arrive at the Giant's Causeway in the worst of the afternoon coach traffic. If you can time it, eat in Ballycastle, then carry on. The best light at the Causeway is often late afternoon anyway.
The Final Stretch to the Giant's Causeway
From Ballycastle to the Giant's Causeway is only about twenty minutes, but the road keeps giving. You pass by Carrick-a-Rede and Ballintoy Harbour — both worth their own stops, and we have separate guides for those. The cliffs get darker and more vertical. Then suddenly the visitor centre appears, the car parks fill both sides of the road, and you are there.
The stones are extraordinary, but by the time you arrive you have already driven one of the best coastal roads in Europe. That is the part I want you to remember. Read our full Giant's Causeway by car guide for parking, timing and how to approach the stones without losing your patience.
What the Drive Time Actually Looks Like
The straight answer is about an hour and ten minutes if you do not stop. Nobody does this drive in an hour and ten minutes. A realistic Belfast to Giant's Causeway day, with stops, is six to eight hours from first key turn to last photograph. Here is how it breaks down.
| Segment | Non-stop driving | Realistic with stops |
|---|---|---|
| Belfast to Larne | 35 min | 45–60 min |
| Larne to Cushendun | 45 min | 1.5–2 hrs |
| Cushendun to Ballycastle | 30 min | 1–1.5 hrs |
| Ballycastle to Giant's Causeway | 20 min | 30–45 min |
Add an hour at the Giant's Causeway itself, plus whatever you spend at Glenariff, Cushendun, or Ballycastle. If you are doing the Torr Head Road, add another thirty to forty minutes.
What to Skip, and What Not To
If you are short on time, skip the Torr Head Road and do not try to visit Carrick-a-Rede on the same day unless you have a timed ticket already. Do not skip the Glens section between Cushendun and Cushendall. Do not skip Ballycastle if you need fuel or food, because there is not much after it. And do not, under any circumstances, try to park at the Giant's Causeway without a plan.
The other thing not to skip is the detail work. Northern Ireland is a different jurisdiction from the Republic. The speed limits are in miles per hour, the currency is pounds sterling, and the road signs change. If you are arriving from Dublin or the south, read our Ireland driving rules guide for the differences that actually matter on the road.
The Car You Want for This Coast
This is where I put my cousin hat on. The Antrim Coast Road is not difficult, but it is narrow, winding, and full of rental cars with confused drivers. You want something compact, automatic if you are not used to manual, and covered for the whole island including Northern Ireland.
Some rental companies treat Northern Ireland as a cross-border extra. My Irish Cousin does not. We cover both sides of the border as standard, with zero excess, no deposit beyond a €1 credit card pre-authorisation, and full roadside assistance if you need it. That matters on a route that takes you back and forth across a jurisdiction line most people do not even notice. If you are starting in the Republic and heading north, read our guide to taking a rental car from Ireland to Northern Ireland.
The drive from Belfast to the Giant's Causeway is not a warm-up act. It is half the show. Take the whole day, let the Glens slow you down, and arrive at the stones in the evening light if you can. That is when the coast looks most like itself.
