I had a cousin from Philadelphia pull over at the first lay-by past Carrickfergus and tell me she finally understood why I kept talking about the north coast. She had flown into Dublin the night before, picked up the car, and driven the A2 up through Larne and Ballygalley. By the time the road turned inland at Glenarm and then opened out again above Carnlough, the Irish Sea was on her right, the Antrim hills were on her left, and she realised the rest of her trip had been a rehearsal for this stretch.
The Causeway Coastal Route is only about fifty miles as the crow flies, but the coastline makes you earn every one of them. It is not a single road with a neat beginning and end. It is a collection of A-roads, B-roads, harbour lanes, and cliff-top lay-bys that together make up one of the great drives of the British Isles. Some visitors come for the Giant's Causeway and treat the rest as scenery. That is a mistake. The best part of the day is often the stretch between the famous stops, where the road narrows, the hedges drop away, and the Atlantic fills the windscreen.
This article pulls the whole route together. The detailed guides below cover each stop in turn. Here I want to give you the overview: how to drive the route, where to stop, what to skip, and how to make sure your rental car is as ready for Northern Ireland as you are.
Why the Causeway Coastal Route Is Worth the Full Day
There are shorter drives in Ireland that look good in a photograph. There are longer drives that feel like a commute. The Causeway Coastal Route is the rare stretch that rewards you mile for mile without wasting an hour. It runs from Belfast in the east to Derry~Londonderry in the west, hugging the coast for most of the way, and it packs in more distinct scenery per kilometre than almost anything else on the island.
You get fishing villages, castle ruins, rope bridges, basalt columns, beaches backed by cliffs, and inland detours through the Glens of Antrim. You also get the practical advantage of a single road that is easy to follow: the A2 for most of it, with the B roads taking you down to the specific sites. If you are the kind of driver who likes a clear plan in the morning and a full memory card by evening, this is your route.
What makes it different from the Ring of Kerry or the Wild Atlantic Way is the density. On the Wild Atlantic Way you can drive for an hour between highlights. On the Causeway Coastal Route the highlights are stacked on top of one another. That is a blessing and a trap. The blessing is variety. The trap is trying to see all of it in one go.
The Route at a Glance
The full route is roughly 120 miles from Belfast to Derry, depending on how many detours you take. Most cousins do it as a long day trip, starting in Belfast and finishing at the Giant's Causeway or pushing on to Portrush. A two-day version lets you walk the rope bridge, tour the castle interiors, and stop in Bushmills without checking your watch every ten minutes.
The table below is a rough guide, not a prescription. Driving times are optimistic and assume you do not stop. You will stop. The point is to show you how the day divides into chunks, so you can decide where to spend your time.
| Section | Distance | Highlights | Time |
|---|---|---|---|
| Belfast to Larne | ~20 miles | Harland & Wolff cranes, coastal suburbs | 45 min |
| Larne to Cushendun | ~25 miles | Glens of Antrim, Glenarm, Carnlough | 1 hr |
| Cushendun to Ballycastle | ~20 miles | Torr Head, Murlough Bay, Fair Head | 1 hr |
| Ballycastle to Giant's Causeway | ~15 miles | Carrick-a-Rede, Ballintoy, Dunseverick | 1–1.5 hr |
| Giant's Causeway to Portrush | ~10 miles | Dunluce Castle, White Rocks beach | 45 min |
| Portrush to Derry | ~35 miles | Portstewart, Mussenden Temple, Downhill Beach | 1 hr |
Those times are driving-only. Add parking, walking, queues, and lunch, and a one-day Belfast-to-Causeway run is a ten-hour day. That is doable, but it is not relaxing. My honest view: if you can stretch it to two days, you will see more and enjoy it more.
Where to Start and Where to Finish
Most people start in Belfast because that is where they are staying or where they flew in. The city gives you two advantages: a full tank of fuel and a morning head start before the coaches reach the coast. From Belfast City Centre you join the A2 at the docks and follow it north and east. The first twenty minutes are urban and industrial; do not judge the route by them. The scenery starts in earnest past Whitehead.
The natural finishing point depends on your stamina. Giant's Causeway is the obvious headline, and many cousins turn around there. If you keep going, Portrush is a good place for dinner, Portstewart for a beach walk, and Derry~Londonderry for a second night in a completely different city. For a detailed breakdown of the eastern half, see the Belfast to Giant's Causeway drive.
If you have already seen Belfast, consider starting in Derry and driving east. You get the same coast in reverse, the sun behind you in the afternoon, and the Giant's Causeway as a grand finale before you turn for home.
The Best Stops from East to West
I am going to list these roughly in the order you meet them driving Belfast to Derry. You do not need every stop. In fact, trying to do all of them in one day is the most common mistake I see. Pick four or five, leave the rest for a return trip, and you will have a better day than the people racing from car park to car park.
The Antrim Coast Road itself is the first proper highlight once you clear the Belfast suburbs. Glenarm has a walled garden and a harbour that feels like it has not changed in a century. Carnlough has a single street, a harbour, and a bay that catches the evening light. Cushendall and Cushendun are small, friendly, and useful for a sandwich. The Antrim Coast Road guide covers the practical side: where to pull over, where the coaches bunch up, and how to time it.
Northern Ireland's film tourism is impossible to ignore once you are on this coast. The Dark Hedges and Ballymoney is the most photographed stop, and it is genuinely atmospheric early in the morning before the coaches arrive. Further along, the Game of Thrones filming locations covers the full set: Ballintoy Harbour, the Murlough Bay viewpoint, and the other sites within a short drive of the main road. If you want the indoor exhibition, the Game of Thrones Studio Tour explains how to get there from Belfast or the coast.
Carrick-a-Rede is the one stop where the queue can eat your whole morning. You need a timed ticket to cross, and the car park fills early in summer. The walk out to the bridge is the real reward even if you do not cross. My Carrick-a-Rede rope bridge has the booking details and the parking strategy.
Then comes the Giant's Causeway. This is the reason most people come. The basalt columns are as good as the photographs suggest, but the experience depends heavily on timing and parking. The visitor centre car park is expensive and fills with coaches by mid-morning. The alternative is to arrive early or late, park at the railway line car park, and walk in. The Giant's Causeway by car tells you exactly how to do that without getting caught in the coach drop-off.
Dunluce Castle sits on the cliff edge just west of the Causeway and is worth the stop even if you only view it from the road. Further west, Portrush is useful for food and a beach walk, while Portstewart Strand is a long, flat beach that works well for families. The Dunluce Castle and the Mussenden Temple and Downhill Beach cover the western half of the route in more detail than I can fit here.
Practical Driving Notes for the Route
The Causeway Coastal Route is not a difficult drive, but it is not a motorway either. The A2 is mostly two lanes with occasional narrow sections, and the side roads down to villages and car parks can be tight. If you are not comfortable with oncoming traffic on a narrow road, take the bigger pull-outs and let faster traffic pass you.
Three things catch people out. First, Northern Ireland uses miles per hour, not kilometres. Your car's speedometer probably shows both, but make sure you are reading the right scale. Second, mobile signal is patchy along parts of the coast, so download offline maps before you leave Belfast. Third, coach traffic is heaviest between 10:00 and 16:00 from May through September; plan your Giant's Causeway and Carrick-a-Rede stops outside those hours.
Parking can also surprise you. The main sites charge for car parks, and some fill by mid-morning in peak season. Carry pound coins or a working contactless card for the smaller car parks. At the Giant's Causeway, the railway line car park is a useful alternative to the visitor centre if you are happy with a short walk.

Where to Base Yourself
Belfast is the most practical base if you want restaurants, museums, and a city atmosphere. It adds about an hour each way to the eastern end of the route. Ballycastle puts you in the middle of the best scenery and within twenty minutes of both Carrick-a-Rede and the Causeway, but it is smaller and quieter. Portrush has the beach, the golf, and more accommodation options for families.
If you are doing the full Belfast-to-Derry run, consider staying the night in Portrush or Portstewart and finishing in Derry the next day. Derry~Londonderry is one of the most interesting small cities on the island and deserves an evening, not just a drive-through. Its walls, murals, and food scene make a strong case for an overnight stop.
For a quieter base with direct access to the coast, Bushmills and Portballintrae are both within a few minutes of the Giant's Causeway. They lack the nightlife of Portrush but win on peace and proximity.
The Honest Truth About Doing It in One Day
You can drive Belfast to Giant's Causeway and back in a day. Thousands of people do it on coach tours. What you cannot do is drive it, walk the Causeway, cross Carrick-a-Rede, explore Dunluce Castle, have a proper lunch, and still be relaxed by dinner. Something has to give.
My advice for a one-day trip: start by 08:00, skip at least two of the minor stops, pre-book Carrick-a-Rede if you want to cross, and aim to reach the Giant's Causeway by 15:00 at the latest. If you are starting later than 09:00, cut Carrick-a-Rede or the western end. The route will still be one of the best days of your trip; it just will not be everything.
The coach tours do a remarkable job of packing the highlights into eight hours, but they are packing, not savouring. If you are driving yourself, you have the advantage of choosing your own pace. Use it. A rushed day on the Causeway Coast is still beautiful, but a slow day is unforgettable.
How My Irish Cousin Covers the Whole Island
The Causeway Coastal Route is one of the best examples of why it matters which rental company you choose. The route crosses jurisdictions, mixes rural roads with coastal roads, and puts you a long way from the nearest depot if something goes wrong. My Irish Cousin treats Northern Ireland as part of the same rental at no extra cost: the same zero excess, the same toll device, the same roadside assistance, and the same replacement-car guarantee.
That means you can pick up in Dublin, drive the taking a rental car into Northern Ireland, loop the coast from Belfast to Derry, and drop back in Shannon without ever wondering whether your cover switched off at the border. There is no cross-border fee, no extra insurance product to buy, and no separate phone number if you need help near Ballycastle. It is one island, one quote, one set of terms.
If you are comparing options, the things to watch are the ones this route exposes: cross-border charges, excess amounts, and what happens if the car becomes undrivable. A low headline rate means little if you are paying separately for every jurisdiction and every tyre.
A Final Word on Taking Your Time
The Causeway Coastal Route does not reward speed. It rewards the willingness to pull over, get out of the car, and look at the same view for five minutes longer than your itinerary allows. The best moments I have had on this coast were not at the paid attractions. They were at a random lay-by above Torr Head, in a pub in Cushendun, and on the walk down to Ballintoy Harbour when the evening light turned the water silver.
Drive it in whatever direction suits your trip. Start in Belfast or Derry, do it in one day or three, see every stop or see only two. Just do not try to race it. The coast has been here for millions of years. Give it at least one full day of your own.
