Guérande lies 80 km west of Nantes, 2,000 hectares of salt pans worked by paludiers who hand-rake fleur de sel and the coarser grey sea salt.
Tip: Terre de Sel at Pradel runs guided marsh walks seven days a week year round, but booking ahead is compulsory rather than optional.
Le Croisic closes the Guérande peninsula west of Nantes, with 27 food traders under its halles and fishmongers selling straight off the criée.
Tip: The halles trade on Thursday and Saturday mornings, plus Tuesdays in July and August; the sea and terroir market runs Fridays at the criée.
Trentemoult in Rezé faces Nantes across the Loire, a painted old fishing village whose narrow alleys open onto lively quayside terraces at dusk.
Tip: The Navibus leaves Gare Maritime every ten to twenty minutes on weekdays on a standard tram ticket, so the crossing costs no more than a bus ride.
Clisson sits half an hour up the tram-train line from Nantes, an Italianate town of Muscadet cellars, a wooden market hall and the Hellcity brewpub.
Tip: The market trades under the halles on Tuesday and Friday mornings; Hellcity pours its own beer seven days a week beside the Hellfest site.
Le Pallet, a tram-train stop south of Nantes, holds the Musée du Vignoble Nantais, where the galleries on Muscadet end in a guided tasting session.
Tip: Entry is €6 with under-12s free, and the museum shuts on Saturdays outside the summer, so plan a weekday or a Sunday.
La Haie-Fouassière is the first vineyard stop out of Nantes, a village that lent its name to the fouace and throws a Muscadet weekend each autumn.
Tip: Fouace et Muscadet en fête takes the streets on the last weekend of September, with an oyster bar, a producers' market and free entry.
