Nature
The Causeway itself
Walk down the access road (or take the shuttle from the visitor centre) to the basalt columns at sea level. Most people stop at the first cluster — keep going past the Organ and the Camel toward the Shepherd's Steps for the best of it without the queue. The hexagons are slippery when wet; mind your step.
Good to know · The stones are free to access — the National Trust charges for the visitor centre, audio guide and car park. Park-and-walk options exist in Bushmills if you'd rather not pay the centre fee.
