Why go to Northern Ireland?
Northern Ireland fits into a pocket handkerchief, and that is precisely what makes it one of the most packed road trips in Europe. In less than an hour's drive from Belfast, you go from the industrial docks where the Titanic was built to the basalt columns of the Giant's Causeway, then to castle ruins clinging to the cliff. Nothing is far, everything flows, and the light changes ten times a day beneath an Atlantic sky that never sits still.
It is also a land of stories. Here the landscapes fed the Celtic legends of the giant Finn McCool, then the sets of Game of Thrones, and in between the painful history of the Troubles, still legible on the painted walls of Belfast and Derry. So you travel as much through memory as through geography, with local guides who tell the story of their city without holding back.
The practical context often surprises visitors: Northern Ireland is part of the United Kingdom, so you pay in pounds sterling, drive on the left and distances are shown in miles. Yet the border with the Republic of Ireland is invisible; you cross it without a single checkpoint. This guide covers the highlights of the Causeway Coastal Route and the two main cities, enough to build a three- to five-day trip with no dull moments.

How much does a trip to Northern Ireland cost?
Northern Ireland is paid for in pounds sterling (GBP), not in euros like the neighbouring Republic: remember to withdraw or pay in the right currency, especially at the pump. Prices are close to those in the rest of the United Kingdom, with accommodation on the pricier side. The amounts below are per person per day, excluding car hire.
| Style | Per day | What it covers |
|---|---|---|
| Backpacker | £55-80 (approx. €65-95) | Hostel or guesthouse, Ulster fry and pub grub, coastal sites, shared car. |
| Comfort | £110-170 (approx. €130-200) | Good hotel or B&B, one proper meal a day, distillery and museums, a car for two. |
| Luxury | £250 and up (approx. €290) | Exceptional address such as the Culloden, fine dining, guided experiences. |
The currency is the pound sterling (GBP), not to be confused with the euro used in the Republic of Ireland. Contactless cards are accepted almost everywhere, even in small shops and car parks. Still, bring a little cash in pounds for markets and tips. Some Scottish or Northern Irish banknotes may look unfamiliar, but they are legal tender.
Is Northern Ireland safe?
Northern Ireland is now a very safe destination, on a par with the rest of the United Kingdom and Western Europe. The Troubles have been a thing of the past since the Good Friday Agreement of 1998, and both towns and countryside can be explored without any particular worry. Petty crime remains low, including in the districts of Belfast and Derry once scarred by the conflict, now open to tourism and proud to tell their story.
Simply stay alert around certain symbolic dates, notably the July marching season, when a few gatherings can create localised tensions and disrupt traffic: just keep away from the parades. The usual precautions are enough: keep an eye on your belongings at tourist sites, and on the coast follow the signs near the cliffs and along wind-exposed paths.
What to see and do in Northern Ireland
- the Giant's Causeway
- Titanic Belfast
- the Dark Hedges
- Carrick-a-Rede Rope Bridge
- Dunluce Castle
The Giant's Causeway
Around 40,000 hexagonal basalt columns tumble down to the sea, so regular you would swear they were man-made: science speaks of a lava flow that cooled 60 million years ago, while legend prefers to see the causeway built by the giant Finn McCool. A UNESCO World Heritage Site, it is reached from a modern National Trust visitor centre, from where a shuttle bus or a path leads down to the columns in about fifteen minutes. Carry on along the wilder clifftop path, which offers the most photogenic viewpoints. The visitor centre ticket is expensive, but access to the site itself remains free for those arriving on foot via the coastal path. The best time is early morning or late in the day, when the coaches have gone and the light skims across the basalt.
Titanic Belfast
On the former Harland & Wolff shipyards, on the exact spot where the liner was designed and launched in 1911, a sharp-edged steel building evokes both a ship's bow and an iceberg. Inside, nine immersive galleries trace industrial Belfast at the start of the 20th century, the construction of the ship, its luxury, then the sinking and its echoes up to the discovery of the wreck. You even ride a small gondola that simulates the descent through the hull under construction. Right next door floats the SS Nomadic, the last surviving White Star Line ship. Allow two to three hours and book a time slot online, as it can get very busy. It is the most comprehensive museum in the world on the subject, and well worth the price.
Belfast
Northern Ireland's capital has traded its post-conflict reputation for a very real creative energy, concentrated in the Cathedral Quarter with its cobbled lanes, live-music pubs and street-art murals. The Edwardian City Hall, monumental and free, marks the centre, while St George's covered market, open at weekends, serves up seafood in a fine Victorian hall. To understand the city, nothing beats a black cab tour: a driver takes you along the political murals of Falls Road and Shankill Road, on either side of the so-called peace walls, and recounts the Troubles with striking frankness. Add Crumlin Road Gaol, a former prison turned museum. Allow at least one full day, and keep an evening for the pubs in the centre.
A night at the Culloden estate
About ten kilometres east of Belfast, on the shores of Belfast Lough, the Culloden Estate & Spa occupies a 19th-century former bishop's palace surrounded by gardens and woods. The interior unashamedly cultivates baronial luxury: wood panelling, fireplaces, antiques, hushed lounges where afternoon tea is taken as it was in the last century. The hotel has a full spa with an indoor pool, a fine-dining restaurant and the more relaxed Cultra Inn. It is the place to book for a sumptuous, peaceful interlude, while staying a quarter of an hour from Titanic Belfast. Ideal for a night bridging the city and the coast. Book ahead in high season, as the best rooms with lough views go fast.
The Dark Hedges
This avenue of two-hundred-year-old beech trees, planted in the 18th century by the Stuart family, has become a global icon since Game of Thrones turned it into the King's Road. The trunks lean and intertwine above the road, forming a ghostly green tunnel, magnificent in the morning mist. The visit takes just a few minutes, but the atmosphere justifies the inland detour, not far from Ballymoney. Traffic is now banned to protect the roots: park in the nearby car park and walk to the avenue. Come early in the morning or on a weekday: in the middle of a summer's day, a photo without people becomes a challenge. Autumn, when the leaves turn red, offers the most spectacular setting.
Carrick-a-Rede Rope Bridge
Strung almost thirty metres above the waves, this bridge of ropes and planks links the coast to a tiny rocky islet that salmon fishermen once crossed. The crossing lasts only a few seconds, but the drop beneath your feet and the Atlantic wind make it a memorable little thrill, with no real danger thanks to the handrails. The superb access path follows cliffs and turquoise coves, with views on a clear day as far as Rathlin Island and Scotland. Run by the National Trust, the site requires online booking with a time slot, essential in summer. Bring good shoes and a windproof jacket. The best time is early morning, before the crowds.
Dunluce Castle
Perched on the edge of a sheer cliff plunging into the Atlantic, the ruin of Dunluce is one of the most dramatic silhouettes in Ireland, especially at sunset when the stone turns gold. A MacDonnell stronghold in the 16th and 17th centuries, it was partly abandoned after part of the kitchens reportedly collapsed into the sea one stormy night. The site is said to have inspired Hogwarts and served as a Game of Thrones location. The visit takes about an hour, with a small visitor centre explaining the history of the place. It sits ideally on the road between the Giant's Causeway and Portrush. Come in late afternoon for the light, and in strong wind to feel the full power of the setting.
The walls of Derry/Londonderry
The province's second city has two names depending on the community, and remains the only city in Ireland whose walls survive intact all the way round. Built in the early 17th century, the ramparts can be walked in a circuit of just under an hour, offering a plunging view over the Catholic Bogside district. It is there, below, that you find the large murals commemorating Bloody Sunday in 1972, now explained without varnish. The Free Derry Museum and the Peace Bridge, arching over the Foyle, round off a visit steeped in history but turned towards reconciliation. Located in the west near the border, the city makes a good stop between Donegal and the Causeway Coast. A local Bogside guide greatly enriches the visit.
How many days, and which itinerary?
Three days are enough for the essentials: a day in Belfast (Titanic, black cab tour, Cathedral Quarter), then two days on the Causeway Coastal Route, one of the most beautiful coast roads in Europe, unrolling its cliffs, villages and iconic sites between Belfast and Derry. Four to five days let you add Derry as a full stop, the Glens of Antrim, a distillery and a few hikes. In practice, you can easily link the Giant's Causeway, the Dark Hedges, Carrick-a-Rede and Dunluce in one full day from Bushmills or Portrush. If you are combining Northern Ireland with the Republic, count this circuit as a three-day loop grafted onto a wider trip, entering via Belfast and leaving towards Donegal via Derry.

Getting there and getting around
Getting to Belfast is simple: the international airport is about thirty minutes from the centre, with direct flights from several European cities depending on the season, and a second, smaller airport, George Best Belfast City, mainly serves UK routes. Many travellers also land in Dublin, about two hours south by road or bus, without ever meeting a border check. Direct buses link Dublin and its airport with Belfast several times a day, and the Enterprise train connects the two capitals in just over two hours. Once there, central Belfast is best explored on foot, but the coast is far better discovered by car.
For the Causeway Coastal Route, a car is a must: the sites are scattered and poorly served by public transport. Remember that traffic drives on the left, and all distances and speed limits are in miles, not kilometres. Fuel is paid for in pounds sterling, not euros, including at the pump, so bear that in mind if you are arriving from the Republic. The roads are in good condition and the distances short, but the narrow coastal roads call for care. A contactless bank card works everywhere, and parking at the main sites is often paid. If you hire a car in Dublin, check that the insurance covers crossing into Northern Ireland.
Where to stay in Northern Ireland?
Belfast is the best base for one or two nights in the city. The Cathedral Quarter and the centre have the most characterful addresses and boutique hotels, within walking distance of the pubs, City Hall and St George's Market. For a sumptuous stay away from the bustle, the Culloden Estate & Spa, to the east on the shores of the lough, offers the most refined experience in the region. Youth hostels and family-run guesthouses round out the options for tight budgets, often with a warm welcome.
On the coast, it pays to sleep near the main sites rather than make the round trip from Belfast. The village of Bushmills, famous for its distillery, and the seaside resort of Portrush put the Giant's Causeway, Dunluce and Carrick-a-Rede a few minutes away. The Bushmills Inn, a former coaching inn with peat fires, is the quintessential characterful stop. Livelier Portrush and Portstewart line up seafront hotels, guest houses and holiday lets, handy for fanning out along the whole Causeway Coastal Route.

What to eat in Northern Ireland?
The signature breakfast is the Ulster fry: eggs, bacon, sausages, grilled tomato and, above all, two local specialities, fried soda bread and potato bread. Hearty, it will keep you going through a whole morning of coastal walking. The Atlantic coast also offers very fresh seafood, oysters, mussels, crab and smoked fish, served in seaside pubs and more ambitious restaurants alike.
The essential drink is Bushmills whiskey, from the oldest licensed distillery in the world according to the house, which you can tour and taste on site, a stone's throw from the Giant's Causeway. Belfast has established itself as a genuine food destination, with award-winning restaurants around the Cathedral Quarter and St George's Market. For something sweet, don't miss a warm scone with strong tea, and try champ, mashed potato livened up with spring onions.
Entry requirements
A passport is required: EU ID cards are no longer accepted. EU, US, Canadian and Australian visitors travel without a visa but must apply online for an Electronic Travel Authorisation (ETA) before departure. Irish citizens need neither.
Rules change: check your own government's travel advice before you go.
Frequently asked questions about Northern Ireland
Can you visit Northern Ireland without a car?
Belfast and Derry are easy to explore on foot and by public transport, and organised day tours link Belfast with the Giant's Causeway. But to explore the Causeway Coastal Route and its scattered sites freely, a car remains by far the most practical solution.
How many days should I plan?
Three days cover the essentials, one day in Belfast and two on the coast. Four to five days let you add Derry, the Glens of Antrim, a distillery and some proper hikes, without rushing from one site to the next.
When is the best time to visit?
From May to September, for long days and milder weather, with a peak in visitors in July and August. May, June and September offer the best compromise between light, manageable crowds and sites at their best.
Is it really safe, given the history of the Troubles?
Yes, very safe. The conflict ended in 1998 and the region can be visited as calmly as the rest of the United Kingdom. The former flashpoint districts, in Belfast as in Derry, are now open and welcoming places of remembrance.
