Introduction
The Nantes to Galway road trip is a 1,200 km Atlantic odyssey that crosses three countries, two sea crossings, and a dozen microclimates.

You'll drive the A11, A81, and M4, plus Irish N-roads. Estimated driving time: 16-18 hours excluding ferries, but plan 3-4 days to uncover gems. Is it worth driving Nantes to Galway? Absolutely—this route stitches together Brittany's megaliths, Cornwall's clifftops, and Galway's craic.
The journey begins in France's 'City of Dukes' and ends in Ireland's cultural heart. Along the way, you'll traverse the Loire-Atlantique, cross the English Channel from Roscoff to Plymouth, and hug the Wild Atlantic Way.

Natural Landscapes and Local Commerce
From Nantes, the Loire estuary gives way to Brittany's bocage: hedgerows, pink granite, and menhirs. Stop at Carnac (1h detour) to see 3,000 standing stones. UNESCO World Heritage site, older than Stonehenge. Then, the Roscoff ferry crosses the Celtic Sea—dolphins often sighted. In Devon, Dartmoor National Park offers tors and ponies; take the A30 to see Widecombe-in-the-Moor. Cornwall's coast near St Ives is a surf paradise; hidden off-route spot: Tintagel Castle, linked to Arthurian legend (cliffside ruins).
Wales's Snowdonia looms to the north; from Fishguard, the ferry to Rosslare reveals Ireland's green patchwork. The Wild Atlantic Way from Rosslare to Galway passes Hook Lighthouse, the oldest operational lighthouse in Europe. Local commerce thrives on farm shops: in France, buy galettes and cider; in UK, Cornish pasties and clotted cream; in Ireland, brown bread and smoked salmon.
