How do I drive from Downpatrick to Ardglass for the harbour?

Ardglass is southeast of Downpatrick on the County Down coast.

Use the signed road towards Ardglass and navigate to the actual harbour or business rather than simply “Ardglass”, because seafront access and town streets are different from the approach road. The drive is a local road journey, not a motorway or a ferry crossing. If you have a delivery or a larger vehicle, confirm the harbour access with the destination before selecting a narrow local route in satnav.
