From Galway's Burren limestone pavement to the cliffs of Moher, the first leg showcases Ireland's wild Atlantic coast. The drive east crosses the Midlands — flat bogs and farmland — before reaching Dublin's urban sprawl.

• Cliffs of Moher: detour 1 hour from M18.
• Rock of Cashel: near M8 south of Dublin.
• Newgrange tomb: UNESCO site, off M1 north of Dublin.

After the ferry (Holyhead), the A55 hugs the North Wales coast with views of Snowdonia. The M6 through England passes the Peak District and Lake District (stops like The Roaches). Kent's Garden of England offers orchards and vineyards near the Channel.

Local commerce highlights: Dublin's food markets, Welsh wool shops, Cheshire cheese producers, and Kentish hops. In Boulogne-sur-Mer, the Nausicaá aquarium and seafood market are must-visits.

Road quality is excellent on motorways; minor roads in Ireland may be narrow with hidden dips. UK motorways have average lane discipline; France has strict rules (high beam use, emergency lane).
