The road along the Antrim coast

The Causeway Coastal Route follows the east and north coasts of Northern Ireland for nearly 200 kilometres, from Belfast to Derry~Londonderry. North of Larne, the Antrim Coast Road, cut into the rock between 1832 and 1842, runs right beside the waves, below cliffs of white chalk and then black basalt. It crosses the Glens of Antrim, green valleys that run down to the sea. At Glenariff, a path on wooden boardwalks leads to the waterfalls.

After Cushendun and its white cottages, a small single-track road climbs to Torr Head. This is the point of Northern Ireland closest to Scotland, which lies about twenty kilometres away. The road comes back down to Ballycastle, where the ferry leaves for Rathlin Island. Further on, the rope bridge at Carrick-a-Rede, 20 metres long, hangs 30 metres above the rocks.

Along the north coast come the Giant’s Causeway, the ruins of Dunluce and Mussenden Temple, above Downhill Strand. Derry, a walled city on the Foyle, is less than an hour away.

Castles and city walls

The ruins of Dunluce stand on a headland, near Bushmills. In the 16th century, the MacDonnells, a clan of Scottish origin, took the castle from the MacQuillans and made it their stronghold. In 1588, a ship of the Spanish Armada, the Girona, was wrecked close by. Her cannons were set up in the castle and her cargo paid for the building work. According to tradition, part of the kitchens fell into the sea one day.

Near Belfast, Carrickfergus Castle was built in 1177 by the Norman knight John de Courcy. King William III landed there in June 1690.

At the end of the road, Derry has kept its walls from 1613–1619, which you can walk all the way round. They were never taken, not even during the siege of 1689, which lasted 105 days. Below the walls, the Bogside recalls a more recent history: the gable wall of Free Derry Corner and Bloody Sunday of 1972.

The Giant’s Causeway and its legend

The Giant’s Causeway has around 40,000 basalt columns, most of them six-sided. They were formed 50 to 60 million years ago, when a lava flow cooled and cracked. The site has been on the UNESCO World Heritage List since 1986. The cliff paths lead to other formations, such as the Organ and the Giant’s Boot.

According to legend, the Irish giant Finn McCool built it to go and fight the Scottish giant Benandonner. In one version, his wife dresses him up as a baby; seeing the size of the child, Benandonner imagines the size of the father and runs away, tearing up the causeway behind him. Similar columns appear in Scotland, on the island of Staffa, further north.

The Gobbins

Islandmagee, Northern Ireland · 25 minutes from Carrickfergus

A path from 1902 at the foot of the Islandmagee cliffs: walkways, tunnels and bridges just above the waves, among the seabirds. Guided tours only, booked in advance. Reopened in March 2026 after a rockfall, it often closes in rough weather.

Practical notes

When to go
May to September, when the days are long. July and August are the busiest months. Wind and rain are possible all year round.
Getting there
Belfast has two airports and ferries from Scotland and Liverpool. Derry is very close to the Republic of Ireland: check the insurance on your hire car.
Access
Everything is tarmac. You drive on the left; distances are in miles. The Torr Head road, narrow and steep, is not recommended for coaches or caravans: in a motorhome, avoid this detour and stay on the A2 via Glendun and Ballyvoy.
Sleeping in a van
Campsites along the coast, at Cushendall, Ballycastle, Bushmills and Portrush. Book ahead in July and August.
Worth knowing
Carrick-a-Rede is booked online with the National Trust; the bridge closes in high winds. Visitors from the European Union, except the Irish, need a UK Electronic Travel Authorisation (ETA).
Allow
Four days, one more for Belfast or Rathlin Island.

Food on the Antrim coast

In the morning, you get an Ulster fry: eggs, bacon, sausages, soda farl and potato bread, all fried. In the small harbours, you eat salmon and seafood. At the end of August, the Ould Lammas Fair in Ballycastle sells dulse, a dried seaweed, and yellowman, a honeycomb toffee.

In Bushmills, you can visit the distillery. The date 1608 on its bottles refers to a licence to distil granted that year by King James I; the company dates from 1784. In Ireland, it is spelt whiskey, with an e; Scotland writes whisky.
