The story that haunts this land
Giant's Causeway Visitor Centre in Bushmills opened in 2012 as an award-winning sustainable building, starting point for electric shuttles to the rock formations. This visitor center offers interactive exhibitions, films and audio-guides about the volcanic activity that formed these columns 60 million years ago. Here you discover the first documented traces of Fionn mac Cumhaill, mythic figure from the 2nd century whose tales traverse Irish manuscripts. Guided walking tours depart throughout the day toward the Atlantic coast, where legends come alive on the hexagonal stones.
Giant's Causeway itself reveals over 40,000 hexagonal basalt columns formed by volcanic activity, UNESCO World Heritage Site since 1986. The descending path from the Visitor Centre to the coast takes about 15 minutes walking toward these formations extending into the Atlantic Sea. The columns of varying heights require climbing up and down along the coastal causeway, where each stone seems carved by the hand of giant Finn McCool according to Irish tradition.
The Wishing Chair stands as a natural basalt formation shaped like a chair on Giant's Causeway, legendary seat of Finn McCool where visitors have made wishes for centuries. Accessible on foot from the main coastal causeway, this stone throne evokes tales where the Irish giant sat contemplating Scotland before building his causeway to Staffa island. Tradition holds that Finn shaped this seat to watch his Scottish rival Benandonner.
Giant's Boot and The Organ complete the legendary landscape with their evocative shapes: the rock shaped like a giant boot associated with Finn McCool's footsteps, and the tall thin columns resembling an organ, visible along the main coastal path. Giant's Chimneys add their groups of slender columns evoking chimneys in this coastal landscape explorable on foot. Each formation tells an episode of the legend where Finn prepared his battle against the Scottish giant.
The upper path of Giant's Causeway offers panoramic views over all formations from the marked coastal trail of 1.2 to 3.2 km Red Trail, part of the Causeway Coast Way accessible from the Visitor Centre. This final perspective reveals the scope of the geological and mythological challenge: 60 million years of volcanism and 2,000 years of Irish legends carved in Ulster's basalt stone. You leave with certainty of having walked one of Europe's most documented natural wonders, where science and mythology meet on the Atlantic coast.
