If Belfast is not convenient for you, the tour can be accessed at any point along the route.

Get an early start to avoid tour buses on the road and crowds at attractions. Attendance is heaviest at the Giant’s Causeway between 11am and 3pm. The goal is to arrive a by t the Visitor Centre by 10am at the latest. If you leave from Belfast, try to be on the road by 7am.

The route is not complicated. It is well signed and the roads tend to be in good condition making the Causeway Coastal Route a great place to rent a car. If you do drive, we recommend paying the extra money to rent an automatic. The roads are curvy and crowded (even if you are used to driving a standard there is the added challenge of doing it on the opposite side).

Dress for the environment and weather. Wear shoes with good tread and sturdy soles. Consider packing rain gear, a warm fleece, hat, walking sticks, sunscreen, water and snacks in all seasons.
