Île d’Aix is a small crescent of land three kilometres long at the mouth of the Charente, between Fouras and Île d’Oléron and directly opposite Fort Boyard. There are no cars here: people get around on foot, by bike or by horse-drawn carriage, between white houses with colourful shutters, ramparts designed by Vauban and beaches lined with holm oaks. It was on this island that Napoleon spent his last days in France in July 1815, in a house that is now a museum. A boat links it all year round to the Pointe de la Fumée in Fouras in about twenty minutes.

Where is Île d’Aix?

Île d’Aix lies in the Pertuis d’Antioche strait, in the Charente-Maritime department of the Nouvelle-Aquitaine region, off the Fouras peninsula at the mouth of the Charente river. It is a municipality in its own right, Île-d’Aix, with around 250 year-round residents. Crescent-shaped, it measures about 3 kilometres long and 700 metres wide, beaches and rocks included. Fort Boyard rises offshore between the island and Oléron, and from its shores you can see Île d’Oléron, Île Madame and the Fouras peninsula across the water.

The village, enclosed by fortifications, occupies the southern tip facing the mainland: you enter through a fortified gate and drawbridge that open onto Place d’Austerlitz. Beyond it stretch paths lined with pines and holm oaks, meadows and a coastline indented with small coves. The wilder north of the island is home to Fort Liédot and rocky headlands. With cars limited to service vehicles, the island enjoys a rare calm, disturbed only at the height of summer by day-trippers arriving on the boats.

History and culture

Strategically placed at the entrance to the Charente, Île d’Aix has always guarded the naval arsenal of Rochefort. Vauban designed the fortifications of the village and of the Fort de la Rade, later completed by batteries such as Jamblet. In the nineteenth century Fort Liédot was built in the north of the island, while Fort Boyard, out at sea, completed the defence of the roadstead. The church and priory of Saint-Martin recall the island’s religious past, which long predates its forts.

The most famous episode is Napoleon’s stay: from 12 to 15 July 1815 the fallen Emperor lodged in the garrison commander’s house, which he had ordered built in 1808, before surrendering to the British and sailing into exile on Saint Helena. Bought in 1926 by Baron Gourgaud, a descendant of one of his companions in exile, the house was given to the national museums, as was the neighbouring African museum, famous for the dromedary Napoleon is said to have ridden in Egypt. Hollyhocks and low houses complete the island’s character.

What to see on Île d’Aix

Start with the fortified village: cross the drawbridge, wander along Rue Napoléon and Rue Gourgaud, then visit the Napoleonic museum in the Emperor’s house and the African museum, which displays Baron Gourgaud’s hunting collections. The Maison de la Nacre, open from April to September, reveals the craft of mother-of-pearl taken from seashells. At the end of the village, the Fort de la Rade and its ramparts offer a fine view of Fort Boyard and Île d’Oléron, especially in the evening light.

Following the coastal path, you reach the twin white towers of the Île d’Aix lighthouse, nicknamed the island’s giants and protected as a historic monument, then the Jamblet battery, now an interpretation centre. In the north, Fort Liédot can be visited in season and overlooks the Rochefort roadstead. A full tour of the island takes a few hours on foot or a relaxed half-day by bike, with stops on the beaches along the way. To round off the visit, cruises circle Fort Boyard from La Rochelle, Fouras or Oléron.

Beaches, sea and nature

The island has several sand and shingle beaches. The Anse de la Croix, in the south near the village, is the only lifeguarded beach in summer and the most family-friendly. The Grande Plage, Coudepont beach and the coves of the Pointe du Parc in the north are wilder. The sheltered roadstead side offers calmer water for swimming, while the north coast, facing the open sea, is more exposed. Low tide uncovers wide rocky flats, ideal for shore fishing as long as you respect the rules and minimum sizes.

Free from traffic, the island is a haven for nature: fragile dunes, heathland, holm oaks and pines shelter many migratory birds, which can be watched along a discovery trail. Visitors are asked to stay on marked paths, not to pick flowers and to take their rubbish back to the mainland. Around the island, the waters of the Pertuis d’Antioche are perfect for sailing, paddleboarding and sea kayaking, with outings to Fort Boyard, Île Madame or Fort Énet.

Getting there and getting around

The main gateway is the Pointe de la Fumée in Fouras, some thirty kilometres south of La Rochelle. The Fouras–Aix ferry, organised by the Nouvelle-Aquitaine region, runs all year and crosses in 20 to 25 minutes. As a guide, an adult return costs €11 in low season and €18 to €25 in summer depending on demand, plus €8 to €12 for a bike. Cars stay on the mainland, in car parks near the pier. Timetables and fares change, so check them with the operator before you travel.

In season, other boats serve the island: Compagnie Interîles from La Rochelle, Boyardville on Île d’Oléron or Rochefort, and Navipromer cruises from La Rochelle’s Old Port, often combined with a tour of Fort Boyard. To reach Fouras, the nearest stations are La Rochelle, served by TGV trains from Paris, and Rochefort. On the island everything is done on foot or by bike: rental shops in the village offer bikes and small carts for luggage, and horse-drawn carriages tour the island in season.

Best time to go, budget and entry requirements

The oceanic climate is mild and sunny. May, June and September are the ideal months: the days are long, the sea is warming up and the island stays peaceful. From mid-July to mid-August, day-trippers pour in and the boats are busier, so book your crossing and accommodation in advance. Out of season the island returns to village life, with some shops and restaurants closed, but the Fouras ferry runs all year round. Spring and autumn are also the best times to watch migratory birds passing through.

Accommodation is limited, so book early: as a guide, expect about €100 to €170 a night for a double room at the hotel in season, and from €15 to €22 a night for a dorm bed at the youth hostel, with annual membership. The national museums and Fort Liédot charge a few euros for entry. The currency is the euro; carry some cash for the small shops. French and other EU citizens only need an identity card; other nationalities follow the usual Schengen rules and should check what applies to them. A tourist tax applies.
