Around forty thousand interlocking basalt columns step down from the cliffs into the sea on the north Antrim coast. They formed roughly sixty million years ago as lava cooled and contracted, and they are the only UNESCO World Heritage Site in Northern Ireland.
Most visitors spend ninety minutes here. This guide covers what to look for, where the named formations are, and how the paths connect.

The Three Sections
The Causeway divides into three. The Little Causeway is the first section you reach. The Middle Causeway, better known as the Honeycomb, sits between. The Grand Causeway is the largest and most photographed, extending from Port Noffer towards Pleaskin Head, narrowing gradually as it enters the sea.

The Named Formations
The Amphitheatre is the most striking of them. A curved bay ringed by columns roughly eighty feet high with a broad rounded projection beneath, said to be where Finn McCool seated his guests. The bay rises to around 350 feet.
The Giant’s Organ is a run of tall columns set into the cliff face resembling organ pipes.
The Chimney Pots stand at the eastern end of Port Noffer, four tall isolated columns. Ships of the Spanish Armada mistook them for the towers of Dunluce Castle in 1588. The Girona was wrecked nearby, and the name Port na Spaniagh, the Bay of the Spaniards, comes from that night. Treasure recovered from the wreck is held at the Ulster Museum in Belfast.
The Giant’s Eyeglass and The King and His Nobles are formations along the cliff path towards Port na Spaniagh.
Hamilton’s Seat sits above Horse Shoe Bay at the far end of the clifftop route.
The Wishing Chair and The Giant’s Boot are among the stones themselves.


The Paths
The main path runs about a kilometre down from the visitor centre to the stones, on tarmac, with a shuttle bus for anyone who prefers not to walk the descent. The climb back is the harder direction.
The clifftop path, the Red Trail, runs above the site and gives a wider view along the coast. It involves the Shepherd’s Steps and takes longer. It is protected by railings in the exposed sections, and the view along the towering basalt columns is the reward.
The Legend of Finn McCool
Fionn mac Cumhaill, anglicised as Finn McCool, is among the most prominent figures in Irish mythology. In the best-known version, he builds a causeway across to Scotland to confront the giant Benandonner, then realises on seeing him that he has badly misjudged the size of his rival.
Finn’s wife, Sadhbh, disguises him as a baby. Benandonner arrives, sees the size of the infant, draws the obvious conclusion about the father, and flees back to Scotland, tearing up the causeway behind him. Similar columns at Fingal’s Cave on Staffa are the other end of the same formation, which is what makes the story work as well as it does.

Practical Information
The site and coastal paths are managed by the National Trust. You can walk to the stones without a visitor centre ticket, though the centre covers the geology and the legends and is worth the time in poor weather. We partner with Dalriada Kingdom Tours to offer guided visits to the site.
Summer sees heavy coach traffic between mid-morning and mid-afternoon. Early and late are quieter. Conditions on this coast rarely match Belfast, so bring layers, whatever the forecast says, and wear something with grip because wet basalt is slippery.
Visiting With a Private Driver
Our private Giant’s Causeway tour runs from Belfast along the Causeway Coastal Route, with time built in at each stop rather than a fixed coach schedule.
Most visitors combine the Causeway with Carrick-a-Rede Rope Bridge fifteen minutes away, Dunluce Castle, and the Game of Thrones filming locations along the same coast.
Cruise passengers arriving at Belfast should see our shore excursions page for what fits inside a port call.
Common Questions
Where is the Giant’s Causeway?
On the north Antrim coast between Bushmills and Ballintoy, around sixty miles from Belfast.
How were the columns formed?
Lava cooled and contracted around sixty million years ago, fracturing into mostly hexagonal columns. The same process created Fingal’s Cave in Scotland.
How long do I need?
Ninety minutes for the stones. Two hours or more with the clifftop path.
Is it free?
You can walk to the stones without charge. The visitor centre and car park are ticketed.
How many columns are there?
Roughly forty thousand.
Can I get there without a car?
Public transport runs from Belfast and Coleraine but takes considerably longer. Most visitors drive or take a tour.
Is it suitable for limited mobility?
The shuttle covers the descent to the stones and the main path is surfaced. The clifftop route is not accessible.
