Armagh to Westport Road Trip: Ultimate Guide to Hidden Gems

This 180-kilometer route from Armagh to Westport crosses the heart of Ireland, linking the ecclesiastical capital of the north with the scenic gateway to the west. The journey follows the A3 through County Armagh, then the N87 and N5, passing through the historic town of Longford before traversing the drumlin landscape of County Roscommon and into County Mayo.

One little-known fact: the A3 between Armagh and Monaghan was once part of the ancient Slí Midhluachra, a medieval highway connecting Ulster to the south. Today, the drive typically takes 2 hours and 20 minutes without stops, but savvy travelers will want to allow 4–5 hours to explore the many attractions along the way.
