The Giant’s Causeway
Geological studies of these formations over the last 300 years have greatly contributed to the development of the earth sciences, and show that this striking landscape was caused by volcanic activity during the Tertiary, some 50–60 million years ago.
In 1986, UNESCO declared it a World Heritage Site due to its geological importance, is home to a wealth of history and legend. There are 40,000 basalt pillars, each with 5 to 7 irregular sides. This process is like the mud cracks seen when mud dries after heavy rains.
Formation of the Giant Causeway
The Giant’s Causeway formed during the Tertiary period from successive volcanic eruptions. These eruptions created multiple layers of basalt, often separated by weathered “Interbasaltic Beds.” The site’s distinctive hexagonal columns formed when a final, thick lava flow pooled into contact with the Sea, which then underwent slow cooling and contraction.
The pillars are polygonal-shaped due to the cooling of the layers of lava and the atomic structure and natural fracturing of basalt. The Giant’s Causeway lies at the foot of the basalt cliffs along the sea coast on the edge of the Antrim plateau in Northern Ireland.
Periods of volcanic inactivity allowed the upper basalt layers to weather, forming the rich, red-colored soils known as the “Interbasaltic Beds.” The characteristic hexagonal columns formed when a particularly thick layer of lava cooled slowly, causing the rock to contract and fracture into these symmetrical shapes.
Over millions of years, erosion by rivers and Ice Age glaciers carved away the surrounding rock, finally exposing the famous columns of the Giant’s Causeway.
The dramatic sight has inspired legends of giants striding over the sea to Scotland. These curious geological exposures and polygonal columnar formations provide a classic locality for the study of basaltic volcanism. The features of the Giant’s Causeway and strata exposed in the cliff also provide an excellent location for understanding the sequences of activity in the Earth’s geological history.
Giant Causeway Tour
The Giant’s Causeway is Northern Ireland’s most popular tourist attraction. A world-class visitor center, aimed at improving both the visitor experience and ensuring the integration of the center within the landscape in order to maintain the property’s outstanding scenic beauty. The World Heritage properties and their surroundings are managed under the spatial planning system through a hierarchy of regional and local policies and plans.
The facilities at the Causeway Centre now include Tourist Information offices, Bureau De Change, Accommodation Booking Service, an Interpretive Audio-Visual Presentation, and a Souvenir Shop. The National Trust is the custodian of the Causeway and provides the National Trust Shop.
Giant’s Causeway walking trail difficulty and length
The walking trails around the Giant’s Causeway offer significant variety in difficulty and length. Easy, shorter options include the site’s own Blue Trail (2.4 km return, 30–45 minutes) and the Yellow Trail, which is shorter than the Red. The moderately challenging Red Trail (up to 3.2 km, approx 1 hour) includes steep steps. For a longer, more demanding experience, sections of the Causeway Coast Way are available, such as the moderate 9 km walk from Dunseverick Castle.

The Blue Trail is the shortest and easiest route, offering an easy 2.4 km, 45-minute return walk that leads directly from the Visitor Centre to the legendary basalt columns.
The Red Trail is a moderate choice, taking approximately 1 hour (up to 3.2 km) to complete. This route follows the clifftops, rewarding hikers with great views of the Causeway from above, but be aware that it involves steep steps.

Longer coastal trails
This moderate stretch of the Causeway Coast Way from Dunseverick Castle to the Giant’s Causeway is a popular, scenic hike. Covering 9 km in about 2 hours and 45 minutes, the trail follows a grassy path along the coastline and features significant ups and downs.
