Epic Road Trip Guide: Dublin to Plymouth Ferry & Drive

The route from Dublin to Plymouth combines a sea crossing with a scenic drive through southwest England. The shortest sea link is the Stena Line ferry from Dublin Port to Holyhead (3h15m), then a 370-mile drive via the M6, M5, and A38, taking around 6h30m driving time (excluding ferry). An alternative is the ferry from Rosslare to Pembroke Dock (4h), adding coastal scenery. This guide covers the Holyhead route as the default.

A historical fact: the A38 between Exeter and Plymouth follows the ancient Fosse Way, a Roman road built in the 1st century AD. On the Welsh side, the A55 along the North Wales coast traces the route of Thomas Telford's London-Holyhead road, completed in 1830.

Infrastructure Safety & Road Quality

• Motorways (M6, M5) are well-maintained, but the A38 has some single-carriageway sections (especially near Plymouth).
• Speed limits: 70 mph motorway, 60 mph dual carriageway, 30-40 mph in towns. Average speed cameras frequent on M5 roadworks.
