In-depth guide · CampingSpirit
From the salt pans near Guérande via the tidal causeway to Noirmoutier, the Vendée coast and the canals of the Marais Poitevin to La Rochelle, the Île de Ré and Oléron: around 550 kilometres of flat country where the tide table matters more than the road map.
The spirit of the route
This coast lives to the rhythm of the tides. In the morning the Passage du Gois still lies under grey water; two hours later you are rolling over wet tarmac, with shellfish gatherers prodding the mud to left and right. Between Guérande and Oléron everything is flat and wide open: white mounds of salt in the pans of the paludiers, oyster parks whose stakes poke out of the mudflats at low tide, pine forests behind long sandy beaches. Through the sliding door you smell seaweed and pine resin, and at night a lighthouse flashes above the dunes. In the Marais Poitevin the mood changes: ash and poplar trees are reflected in green canals, and the only sound is the pole dipping into the water. After that come La Rochelle with its harbour towers, the cycling island of Ré, and the Vauban fortifications at Brouage and Rochefort. Anyone travelling here keeps stages short, gets on the bike often, and plans island trips by the tide table and the shoulder season.
Stage-by-stage plan
1Stage 1: Guérande to Pornic (approx. 65 km)
- The drive
- From the walled old town of Guérande, drive down through the salt pans to Saint-Nazaire and over the Saint-Nazaire bridge across the Loire (about 3.4 km, toll-free, unpleasant for tall vehicles in strong crosswinds) to Saint-Brevin-les-Pins. Continue south on the well-built D213 (the “Route Bleue”) to Pornic. About 1 hour of pure driving time, flat and straightforward.
- Highlights & must-sees
- Guérande salt marshes: the pans, clay banks and salt heaps of the paludiers, best understood at the Maison des Paludiers in Saillé or on guided tours by Terre de Sel; buy fleur de sel directly from the producer.
- Guérande town walls with the Porte Saint-Michel – the ring of walls is completely preserved and can be walked in half an hour.
- Pornic: the Vieux Port with its castle by the water, and the coastal path (Sentier des Douaniers) to small coves and old fishermen’s huts on stilts.
- CampingSpirit overnight tip
-
Official campsite or RV park: In Guérande there is a Camping-Car Park network aire on the edge of town (about 34 pitches, electricity, service point, access with the network card). In Pornic, Camping Le Pâtisseau is a well-equipped choice with electricity, service point and sanitary facilities; the municipal motorhome pitches in Pornic are small and fill up early in summer.
Free camping or nature tip (where legal): Around Guérande, La Turballe and La Baule there are many municipal aires – overnighting in beach and salt-pan car parks, on the other hand, is not permitted, and height barriers are common. In the salt pans themselves the paths between the pans are private; park only in the designated areas.
- Insider tip for campers
- The narrow lanes inside the walls are not for a motorhome – park at the ring of walls and walk in. If you are coming via Nantes: the Nantes Métropole ZFE applies inside the Périphérique and currently excludes only vehicles without a Crit’Air rating (cars registered before 1997, commercial vehicles before 1997 or lorries before October 2001), on weekdays 7–9 am and 4–7 pm; the route via Saint-Nazaire bypasses the city anyway. Market days in Guérande are Wednesday and Saturday; arrive early, otherwise the car parks at the ring of walls are full.
2Stage 2: Pornic to Noirmoutier-en-l’Île via the Passage du Gois (approx. 55 km)
- The drive
- Via Bourgneuf-en-Retz and along the edge of the Baie de Bourgneuf with its oyster parks to Beauvoir-sur-Mer, then on the D948 onto the Passage du Gois: a good 4 km of paved road across the mudflats, flooded twice a day. On the island, continue via Barbâtre and La Guérinière to Noirmoutier-en-l’Île. A good 1 hour of driving time without waiting; your departure depends entirely on the tides.
- Highlights & must-sees
- Passage du Gois: cross at low tide, then walk out onto the sandbanks, where hundreds of shellfish gatherers are out at big coefficients; rescue refuges on stilts with platforms line the route.
- Château de Noirmoutier, the medieval castle in the middle of the main town, with views over the salt pans and harbour.
- Bois de la Chaize: holm oak and pine forest with bathing coves and beach huts at the Plage des Dames.
- CampingSpirit overnight tip
-
Official campsite or RV park: The island has several aires with service points, including Camping-Car Park in Noirmoutier-en-l’Île (about 140 pitches, access with the network card); the tourist office and the municipalities list further aires. If you want electricity and sanitary facilities: Camping municipal de la Pointe at the Bois de la Chaize or Camping Huttopia Noirmoutier between the main town and the beach. Book in summer.
Free camping or nature tip (where legal): On Noirmoutier, sleeping in your vehicle outside the designated aires is strictly prohibited under a municipal order (arrêté municipal) and is enforced; use the aires or campsites instead – beach, forest and harbour car parks are not an option either. On the Gois itself you must not stop, park or stay overnight; the day car parks at the approaches do not allow overnight stays.
- Insider tip for campers
- The crossing is only possible around low tide: according to the Noirmoutier tourist office, from 90 minutes before to 90 minutes after low water; wind and coefficient shift the window, and fog is especially dangerous. The times are posted on boards at both approaches and on the tourist office website – never set off at the last minute, never stop on the Gois, and hose down the underbody after the crossing (salt water). If you miss the window, the Fromentine bridge (toll-free) is the alternative.
3Stage 3: Noirmoutier-en-l’Île to Saint-Gilles-Croix-de-Vie via Saint-Jean-de-Monts (approx. 65 km)
- The drive
- Back south along the island road and over the toll-free bridge to Fromentine, then through the pine forest of the Pays de Monts via La Barre-de-Monts and Notre-Dame-de-Monts to Saint-Jean-de-Monts. Continue via Saint-Hilaire-de-Riez to Saint-Gilles-Croix-de-Vie. A good 1.5 hours; slow going at roundabouts and beach access roads in July and August.
- Highlights & must-sees
- Écomusée du Daviaud in La Barre-de-Monts: life in the Marais Breton with bourrines (clay-plastered, thatched houses) and salt meadows.
- Corniche Vendéenne near Sion-sur-l’Océan: the only rocky coast for miles around, with the Trou du Diable and the rock pinnacles of the Cinq Pineaux.
- Saint-Gilles-Croix-de-Vie: sardine port at the mouth of the Vie, canneries and fish auction, with a view of the yachts and fishing boats in the evening.
- CampingSpirit overnight tip
-
Official campsite or RV park: In Le Fenouiller on the edge of Saint-Gilles there is an aire with a good 40 pitches, electricity and service point; another large aire is near Saint-Hilaire-de-Riez. Campsites line up behind the dunes in Saint-Jean-de-Monts, for example Camping de la Parée du Jonc with electricity, service point and swimming pool – heavily booked in high season.
Free camping or nature tip (where legal): On the Vendée coast almost all municipalities restrict motorhome parking in beach car parks and on waterfront roads, often with height barriers and a night-time ban. In the Forêt des Pays de Monts the forest tracks are closed to vehicles. Plan on using the aires – there are plenty here.
- Insider tip for campers
- The ferry to the Île d’Yeu leaves from Fromentine – motorhomes are not carried across, so take your bike along or hire one over there. The Vélodyssée (EuroVelo 1) runs parallel to the coast through the pine forest: ideal for leaving the vehicle parked for a day. Ask the tourist office for the market days in Saint-Gilles and Saint-Jean-de-Monts – in summer the town centres are barely passable on those mornings.
4Stage 4: Saint-Gilles-Croix-de-Vie to Talmont-Saint-Hilaire via Les Sables-d’Olonne (approx. 45 km)
- The drive
- On the D38 via Brétignolles-sur-Mer to Les Sables-d’Olonne, past the harbour of Port Olona and through the town onto the D949 to Talmont-Saint-Hilaire. A short stage, a good hour; the drive through Les Sables is slow in summer, so avoid the waterfront road (Remblai).
- Highlights & must-sees
- La Chaume in Les Sables-d’Olonne: fishing quarter opposite the old town with the Tour d’Arundel and the Prieuré Saint-Nicolas, reached by small ferry across the channel.
- Port Olona, start and finish harbour of the Vendée Globe single-handed round-the-world race, and the Île Penotte district with shell mosaics on the house walls.
- Château de Talmont, a ruined medieval castle above the marsh, and in the evening the Plage du Veillon with the Pointe du Payré.
- CampingSpirit overnight tip
-
Official campsite or RV park: In Les Sables the Port Olona aire is near the harbour with a service point. In Talmont-Saint-Hilaire the Aire du Lac (La Chapelle) offers a good 40 pitches with electricity and service point, and on Veillon beach there is the Aire Château Guibert – La Plage. Campsite alternative: Camping La Dune des Sables in the north of Les Sables.
Free camping or nature tip (where legal): Les Sables-d’Olonne and Talmont prohibit motorhomes in many beach and waterfront car parks, and at the Pointe du Payré (nature reserve, Conservatoire du littoral) overnighting is taboo. Use the aires; checks in summer are regular.
- Insider tip for campers
- Les Sables is a big town: head straight for the Port Olona aire and go into the centre on foot or by bike rather than looking for a space on the Remblai. The fish auction and the Les Halles Centrales market hall are worth a morning visit.
5Stage 5: Talmont-Saint-Hilaire to Coulon (Marais Poitevin) (approx. 95 km)
- The drive
- Inland via Avrillé to Luçon and through the drained Marais desséché – dead straight roads between canals and cornfields – to Maillezais, then along the edge of the Marais mouillé to Coulon. About 1.5 hours. In Maillezais, Damvix and Coulon the roads become narrow, often running right beside the canal with no guard rail.
- Highlights & must-sees
- Abbaye de Maillezais: Gothic cathedral ruin with monastery buildings on a former island, starting point for punt trips on the Autize.
- Abbaye Saint-Vincent in Nieul-sur-l’Autise with a fully preserved Romanesque cloister, a short detour.
- Coulon: a punt trip with a pole (“pigouille”) through the green canals of the “Venise verte”, if you wish with a guide who ignites marsh gas on the surface of the water.
- CampingSpirit overnight tip
-
Official campsite or RV park: The municipal Aire de l’Autremont in Coulon is within walking distance of the village: about 90 pitches, water, electricity, grey-water and toilet disposal, WC and Wi-Fi. Ask the commune of Coulon for rates and opening times. With more comfort: Camping de la Venise Verte on the edge of the village with electricity, service point and swimming pool, or Camping municipal La Niquière.
Free camping or nature tip (where legal): The Marais Poitevin is a regional nature park and has been awarded Grand Site de France status; overnighting is not permitted on the canal banks and boat landing stages, and many paths by the water are closed to motor vehicles. Small aires in Damvix, Le Mazeau and Arçais offer legal alternatives.
- Insider tip for campers
- You can hire a punt without a guide at the embarcadères in Coulon and Arçais – take a map, as the canals all look the same. Take insect repellent for the evening hours. In the Marais mouillé, do not follow the satnav onto every farm track: many lanes are single-track, with soft verges and weight limits, and vehicles end up in the canal every year.
6Stage 6: Coulon to La Rochelle via Arçais (approx. 70 km)
- The drive
- On narrow roads along the Sèvre via Le Vanneau to Arçais, then through the marsh to Marans and on the wide D137 to La Rochelle. A good 1.5 hours. In La Rochelle do not drive into the old town, but go straight to the aire or the park-and-ride.
- Highlights & must-sees
- Arçais: small punt harbour with the Logis and gardens, quieter than Coulon; cycle loops on embankments into the Marais mouillé.
- Vieux-Port of La Rochelle with the Tour Saint-Nicolas, Tour de la Chaîne and Tour de la Lanterne, plus the arcaded streets of the old town and the Grosse Horloge.
- Aquarium La Rochelle on the harbour basin and the Les Minimes marina, one of the largest yacht harbours on the Atlantic coast.
- CampingSpirit overnight tip
-
Official campsite or RV park: The municipal Aire de Port-Neuf on Boulevard Aristide Rondeau is exclusively for motorhomes: about 170 pitches, vehicle length up to 11 m, payment by card (according to Campercontact €13 in the winter half-year and €15 from April to September for two people, water, electricity and disposal included; check the current rate on site). It is about 3 km along the waterfront to the Vieux-Port, ideal by bike. Campsite near the town: Camping municipal Le Soleil near Les Minimes (check the season beforehand).
Free camping or nature tip (where legal): La Rochelle and the neighbouring communes do not allow motorhomes to overnight in waterfront car parks and residential areas; the Aire de Port-Neuf is the intended solution. In the town-centre multi-storey car parks, height restrictions prevent entry.
- Insider tip for campers
- In 2026 there is no ZFE in force in La Rochelle; check with the Agglomération for changes before you travel. The best way into the old town is by bike (Yélo hire scheme), bus or the Seebus (bus de mer) between Les Minimes and the Vieux-Port. The Vélo Francette links the Marais Poitevin with La Rochelle on cycle paths – a nice alternative for part of the route.
7Stage 7: La Rochelle to Saint-Clément-des-Baleines (Île de Ré) (approx. 40 km)
- The drive
- Over the bridge to the Île de Ré (just under 3 km, toll only in the direction of the island) to Rivedoux-Plage, then on the island road D735 via La Flotte, Saint-Martin-de-Ré and La Couarde between salt pans to Ars-en-Ré and Saint-Clément-des-Baleines. Around an hour, considerably more in summer; the drives through the villages are narrow, with cyclists everywhere.
- Highlights & must-sees
- Saint-Martin-de-Ré: harbour and Vauban fortifications, part of the UNESCO World Heritage site “Fortifications of Vauban” since 2008.
- Phare des Baleines with views over the rock platforms in the west of the island, next to the old lighthouse of 1682.
- Salt pans and the Lilleau des Niges bird reserve near Les Portes and Loix, best by bike; also the black-and-white church tower of Ars-en-Ré.
- CampingSpirit overnight tip
-
Official campsite or RV park: In Saint-Clément-des-Baleines there is a Camping-Car Park aire with about 40 pitches and service point (access with the network card); there are more aires in Les Portes-en-Ré, Saint-Martin-de-Ré and La Flotte – pitches are limited, and the length of stay is often restricted to 24 or 48 hours. Campsites with electricity and sanitary facilities: Camping Les Baleines or Airotel La Plage near the lighthouse.
Free camping or nature tip (where legal): On the Île de Ré free camping is practically ruled out: the communes ban motorhomes from parking overnight outside aires and campsites (generally between 11 pm and 7 am), and checks are made on beaches, in the dunes and in the nature reserves. On the aires the length of stay is often limited to 24 or 48 hours, and camping behaviour is prohibited.
- Insider tip for campers
- Since 2025 the bridge toll for cars costs €4 (15 November to 1 March), €8 (the rest of the time) or €16 (15 June to 14 September and at the weekends around Ascension and Whitsun), depending on the season; whether a separate tariff applies to motorhomes, and how much it is, could not be confirmed – check the current position with the Département Charente-Maritime. Only the trip onto the island is subject to a toll. Leave the camper parked on the island: more than 100 km of cycle paths link all the villages, and in summer Saint-Martin has hardly any room for large vehicles.
8Stage 8: Île de Ré to Le Château-d’Oléron via Rochefort and Brouage (approx. 115 km)
- The drive
- Back over the bridge (toll-free in the direction of the mainland) and on the N137 expressway to Rochefort, then over the Charente bridge and through marshland to Brouage and via Marennes to the toll-free bridge onto the Île d’Oléron. A good 2 hours; a long but easy stage – if you like, stay overnight in Rochefort.
- Highlights & must-sees
- Corderie Royale in Rochefort: the 374 m long rope works of the 17th-century naval arsenal on the Charente, plus the gardens by the river.
- Brouage: fortified town with fully preserved ramparts, once a salt port, now in the middle of the marshland, birthplace of Samuel de Champlain.
- Le Château-d’Oléron: citadel and the colourful oyster huts at the harbour, where artists and oyster farmers work; at low tide, a view of Fort Louvois.
- CampingSpirit overnight tip
-
Official campsite or RV park: Rochefort: Aire Fosse aux Mâts near the Corderie or Camping municipal Le Rayonnement with electricity and service point. In Brouage there is a motorhome area about 200 m from the citadel on the D3 (about 20 pitches, year-round). On Oléron: Camping Les Remparts in Le Château-d’Oléron or the Aire de Dolus-d’Oléron.
Free camping or nature tip (where legal): On Oléron too, many communes restrict motorhome parking in beach and forest car parks, and overnighting is prohibited in the Forêt domaniale de Saint-Trojan. In the oyster-farming areas the access tracks to the parks are working premises, not car parks.
- Insider tip for campers
- The best place to buy and taste oysters is directly at the farms (dégustation) along the Seudre and in Le Château-d’Oléron; the Cité de l’Huître in Marennes explains how they are farmed. To finish, Royan is worth a visit (about 50 km via La Tremblade and the Forêt de la Coubre), or a detour inland to Cognac. At low tide Fort Louvois can be reached on foot from Bourcefranc – mind the tides.
Camping practice & local rules
Wild camping & overnight parking
- France distinguishes between parking (“stationnement”) and camping: a motorhome counts as a vehicle and may park wherever parking is allowed (for a maximum of 7 days in the same place), provided no municipal order (arrêté municipal) says otherwise. Camping behaviour – stabilising legs, awning, table and chairs, draining water – is prohibited outside campsites and aires.
- On the coast between Guérande and Oléron almost all communes have restricted motorhome parking in beach, harbour and waterfront car parks or banned it at night; height barriers are the rule. On the islands of Noirmoutier, Ré and Oléron motorhomes are directed to the aires, and on Ré there is practically a night-time parking ban everywhere outside aires and campsites. Blanket bans for an entire municipal area are open to legal challenge (such bans have been overturned in French courts), but the signs on the spot are what count.
- Wild camping is prohibited on the seashore, in dunes, in sites classés, within 500 m of monuments historiques and near drinking-water abstraction points. Nature reserves such as Lilleau des Niges, the Pointe du Payré and Conservatoire du littoral land are taboo; forest tracks in state forests are closed to motor vehicles.
- You can stay legally overnight on campsites, municipal aires de camping-car and Camping-Car Park sites (access by card), and at producers via France Passion. Apps: park4night, Campercontact, Camping-Car Park.
- Forest fires: the pine forests of the Pays de Monts, Oléron and the Coubre are at risk in summer too; the Vendée and Charente-Maritime can restrict access to forests, and barbecues and fires are prohibited. Check the current situation with the prefectures.
- Gathering shellfish (pêche à pied) is allowed, but with minimum sizes and maximum quantities per species; individual zones are temporarily closed for hygiene reasons. Before gathering, check the notices on site and the information from the prefecture or the ARS.
Waste disposal & supplies
- Service points (“aire de services”, “borne”) can be found in almost every town on the Atlantic coast; the posts (Euro-Relais, Flot Bleu, Raclet and others) work with coins, tokens, credit card or network card. In the Marais Poitevin the aires are less frequent, but there are some in Coulon, Arçais, Damvix and Le Mazeau.
- Empty grey water and the cassette only at the service point – on the sandy soils of the coast and in the canals of the Marais, any discharge is penalised.
- Tap water is drinkable; avoid posts marked “eau non potable”. In summer, water-saving restrictions often apply in the Vendée and Charente-Maritime – no vehicle washing at the posts.
- Salt water: after the Passage du Gois and drives on the beach, rinse the underbody with fresh water; many petrol stations have wash bays for tall vehicles.
- Gas: French exchange cylinders (butane/propane) are available in every supermarket; foreign cylinders are not exchanged. LPG pumps for refilling refillable tanks are rare, mostly at large supermarkets; bring adapters (Dish, Euronozzle).
Vehicle size & traffic rules
- Speed limits: motorhomes up to 3.5 t and combinations up to 3.5 t permissible gross train weight as for cars – 130 km/h on motorways, 110 km/h on expressways, 80 km/h on country roads (90 only where signposted), 50 km/h in built-up areas; in rain 110/100/80. Motorhomes over 3.5 t up to 12 t: 110 km/h on motorways, 100 km/h on expressways, 80 km/h on country roads, speed disc at the rear. Combinations over 3.5 t: 90 km/h on motorways and expressways, 80 km/h on other roads.
- Vehicles over 3.5 t, expressly including motorhomes, must carry the “Angles morts” stickers on the sides and rear (since 2021, €135 fine).
- ZFE and Crit’Air: the Conseil constitutionnel struck down the nationwide abolition of the ZFE on 21 May 2026, so the zones remain and each Métropole sets the classes itself. On this route that mainly concerns arriving via Nantes (ZFE inside the Périphérique, currently excluding only vehicles without a Crit’Air rating, on weekdays at peak times); no ZFE is in force in La Rochelle. Check the position before you travel, and order the Crit’Air sticker (also valid for foreign vehicles) only via certificat-air.gouv.fr.
- Tolls: apart from the bridge to the Île de Ré, the route itself is toll-free (the Saint-Nazaire, Noirmoutier and Oléron bridges are free). For the journey there on the A11, A83 or A10: class 2 for vehicles over 2 m and under 3 m in height up to 3.5 t, class 3 for two-axle vehicles 3 m or more in height or over 3.5 t, class 4 for three or more axles over 3.5 t or 3 m and above.
- Tidal causeway: the Passage du Gois can only be driven around low tide; stopping and parking on the carriageway is prohibited. If you are caught by the water, leave the vehicle and climb onto a rescue refuge – vehicle recovery is expensive; whether your insurance pays depends on the policy – you would do well not to ignore the posted times.
- Alcohol limit 0.5 per mille (new drivers 0.2); phoning at the wheel is prohibited even with a headset. A high-visibility vest for the driver within reach and a warning triangle are compulsory. Bike racks must not cover the number plate or lights.
CampingSpirit packing & preparation checklist
- Tide table for Noirmoutier and La Rochelle (printed or as the SHOM app) – indispensable for the Passage du Gois, Fort Louvois and shellfish gathering.
- Bikes with a sturdy rear carrier: the Vélodyssée, the Vélo Francette and the cycle paths of the Île de Ré are the best means of transport on this route.
- Oyster knife, cut-resistant glove and a cool box – here you buy oysters directly from the farmer.
- Measuring gauge and bag for pêche à pied, plus wellies or neoprene shoes for the mudflats and oyster beds.
- Insect repellent and a mosquito net for the evenings in the Marais Poitevin.
- Garden hose with a spray head, to rinse the salt off the underbody after the Gois crossing and beach car parks.
As of 2026-09. Closures, fees and booking rules change: check official sources before you go.
