Saint-Nazaire 2026: Crit'Air at the Port That Built Liners
Saint-Nazaire, France · ZFE
Saint-Nazaire — the great industrial port at the mouth of the Loire in Brittany/Pays de la Loire, famous for its shipyards (the Chantiers de l'Atlantique, which built the legendary liners Normandie and France and today builds some of the world's largest cruise ships), a colossal WWII German submarine base on the waterfront (now a cultural and visitor site), and Airbus aircraft works — runs a Crit'Air ZFE (foreign cars included) with fines from around EUR 68 for cars. The centre is walkable. Park and walk; the shipyards, the submarine base and the coast are the draws.
Can your car enter Saint-Nazaire?
Saint-Nazaire’s ZFE requires a Crit’Air sticker for every car, including foreign-registered ones, and driving in without one risks a fine from around EUR 68. The Chantiers de l’Atlantique shipyards here built the liners Normandie and France and now construct some of the world’s largest cruise ships. A colossal WWII submarine base on the waterfront survived the bombing that flattened much of the town and today houses museums.
This page covers driving around Saint-Nazaire. For the emission classes and zone boundary, see the Saint-Nazaire ZFE details.
Crit’Air, park and walk
Order the Crit’Air sticker ahead (certificat-air.gouv.fr); without it the ZFE fine is from EUR 68. Park and walk to the shipyard tours (Escal’Atlantic) and the submarine base. France’s limits: 50 km/h urban, 0.05% alcohol.
When the car helps
Keep it for the coast — the resort of La Baule, the salt town of Guérande, the Brière marshes and the Loire estuary — driven from a central car park.

Winter tyres in France — 2026–27 season
Winter tyres are required in France whenever conditions are wintry — 1 Nov - 31 Mar (mountain law, designated departments).
- Tread minimum: 1.6 mm — France sets no separate winter figure.
- Accepted marking: M+S or 3PMSF
- Studded tyres: restricted
- Penalty: Not published by the French authorities. Note: the obligation is only enforceable where the B58/B59 signs have actually been installed (Code de la route art. D. 314-8).
In French the rule is pneus hiver, and snow chains are chaînes à neige — that is the wording on signs, in hire-car paperwork and on any penalty notice.

Frequently Asked Questions
Yes. Saint-Nazaire's ZFE requires a Crit'Air windscreen sticker for all cars, including foreign-registered ones, with the most polluting classes restricted. Order it ahead from the official site (certificat-air.gouv.fr), as it arrives by post. Driving in the zone without a valid sticker risks a fine from around EUR 68 for cars. The walkable, rebuilt centre means most visitors park near the centre and walk in.
Saint-Nazaire is home to the Chantiers de l'Atlantique, one of the world's great shipyards, which built famous transatlantic liners like the Normandie and the France and today constructs some of the largest cruise ships afloat. Visitors can take guided tours (Escal'Atlantic and the shipyard visits) to see the giant building docks and learn the history of ocean-liner construction. It's the town's defining industry and a fascinating draw, on the waterfront.
During WWII the Germans built a colossal, almost indestructible concrete U-boat base (the Base Sous-Marine) on Saint-Nazaire's waterfront, which survived the heavy bombing that flattened much of the town (and the daring 1942 British commando raid on the great dry dock). The vast bunker has been reinvented as a cultural quarter with museums (including Escal'Atlantic, recreating an ocean liner), exhibition spaces and viewpoints. It's a striking and sobering landmark, walkable in the centre.
Use a car park near the centre or the waterfront, with the Crit'Air sticker for the ZFE, then walk. The rebuilt town centre, the submarine base and the seafront are walkable or close together. Parking once and walking is the easy way around, keeping the car for the surrounding coast — the resort of La Baule, the Guérande salt marshes and the Loire estuary.
Not for the compact centre and waterfront, which are walkable, and Saint-Nazaire is on the rail line near Nantes. A car helps for exploring the coast around it — the elegant resort of La Baule with its great beach, the medieval salt town of Guérande and its marshes, the Brière marshland regional park, and the Loire estuary with its artworks — driven from a central car park rather than used in the ZFE centre.
