The station was originally opened on 19 January 1987 to replace the closed Ardrossan Winton Pier railway station.[3] Ardrossan Harbour station is slightly further inland (approximately 220 yards/200 metres to the east) than its predecessor[4] and is sited at the end of a 1-mile (1.6 km) long branch line from Ardrossan South Beach.
The station is unstaffed and consists of a single platform and shelter, a short walk from the "CalMac" terminal building.
