The Giants Causeway (Giant’s Causeway), managed by the National Trust, is Northern Ireland’s only UNESCO World Heritage Site with spectacular rock formations formed 60 million years ago. Deemed as one of the most amazing natural phenomena in the world, the 40,000 interlocking hexagonal basalt columns, packed like commuters on a busy train, huddle the shoreline.

The Red walking trail
1. The start
In front of The Causeway Hotel, built in 1836, overlooking the Atlantic Ocean as the first place for travellers to stay near the rock formations.

With the Visitor Centre on your left, walk on the sloped grass roof, picking up signs for the Red Trail from the rear. There is a plinth with a map and directions.
2. Weir Snout
Continue along the visible path and up a steep hill leading to Weir Snout. A viewfinder provides more information on the views. The Vikings first raided here in small parties, then later with fleets before attempting to conquer the country.

3. Aird Snout
The next vantage point is a headland known as the Aird. Overlooking Port Ganny are boulders that act as a deterrent to people walking out onto this headland. This area is spectacular but dangerous, and there are usually high winds.

4. Shepherd’s Steps
Continuing from Aird Snout, you’ll reach the top of Shepherd’s Steps overlooking Port Noffer. Onwards, the path becomes the Yellow Trail and leads to Hamilton’s Seat, providing an aerial view of the Amphitheatre.

At this point head back towards the Visitor centre and car park.
The Giants Causeway stones
The basalt stones are the main attraction at the Giants Causeway. Deceptive in height, with stones as high as 10m (32.8ft), with a backdrop of spectacular cliffs and seascape. Legend says that Finn MacCool, the folklore giant built the causeway, although a geological explanation is the most plausible formation theory.
