Top Things to Do in Nantes — Complete Guide 2026
Published June 2026 · 12 min read
Nantes is one of those rare cities where the main attraction genuinely doesn't exist anywhere else. A 12-metre mechanical elephant that walks through the streets carrying passengers? Check. A three-storey mechanical carousel of sea creatures? Check. An entire city turned into a summer art gallery by a green painted line? Check. But Nantes' genius is that its imagination doesn't stop at the island. The medieval Bouffay quarter, the Château des Ducs de Bretagne, the Passage Pommeraye, and the beautiful Erdre and Loire riverbanks make Nantes a city you could explore for a week without repeating yourself. Here's the complete guide to the very best things to do. Once you've planned your days, book your eco-hotel in Nantes through IMPT — best price guarantee, 1 tonne CO₂ removed, 5% cashback.
The Big Stuff — Nantes' Unmissable Attractions
1. Les Machines de l'Île
This is the thing everyone comes to Nantes to see, and it delivers. Housed in the former shipyards of the Île de Nantes, Les Machines de l'Île is a mechanical bestiary inspired by the worlds of Jules Verne (born in Nantes) and Leonardo da Vinci. The Grand Éléphant is the star — 12 metres tall, 8 metres wide, constructed of steel and tulip wood, it carries up to 50 passengers on a 45-minute walk through the site, trumpeting its trunk and spraying water. Inside the Galerie des Machines, you'll see the workshops where these creatures are built and maintained, plus rideable mechanical insects and birds. The Carrousel des Mondes Marins is a three-storey marine-themed carousel with 35 moving sea creatures — crabs, squid, submarines, and manta rays — that you can actually ride. The whole complex is a triumph of imagination, engineering, and sheer joy. Allow 3–4 hours. Book Grand Éléphant tickets online in advance for summer visits. Located on the Île de Nantes, 15 minutes' walk from the city centre or Tram Line 1 (Chantiers Navals stop).
2. Château des Ducs de Bretagne
The castle of the Dukes of Brittany is Nantes' historical anchor. Built in the 15th century by François II (the last independent Duke of Brittany) and his daughter Anne of Brittany (who became Queen of France twice), it's a masterpiece of medieval military architecture — a complete circuit of walls and towers surrounded by a water-filled moat. Walking the ramparts is free and gives panoramic views across the city. Inside, the Musée d'Histoire de Nantes occupies 32 rooms and traces the city's history from its Gallo-Roman origins through the Breton era, the Atlantic slave trade (a difficult but essential section), the industrial revolution, and the creative reinvention of recent decades. The museum is modern, engaging, and pulls no punches about the city's complex history. EUR8, courtyard free. Allow 2 hours.
3. Voyage à Nantes — The Green Line Art Trail
Every summer (early July to early September), Nantes becomes one enormous contemporary art gallery. The Voyage à Nantes commissions international artists to create site-specific installations in parks, squares, historic buildings, along the Loire, and sometimes in unexpected locations like disused factories or canal barges. A green line painted on the pavement connects the works in a continuous 10 km route from the city centre to the Île de Nantes and out to the western suburbs. The installations range from playful to profound, and the journey between them becomes part of the experience. Even outside summer, the green line remains as a walking route, and some permanent installations stay year-round. Free. Allow 1–2 days (you can do sections).
4. Passage Pommeraye
Opened in 1843, this exquisite covered shopping arcade spans the steep slope between Rue de la Fosse and Rue Santeuil. It's a masterpiece of 19th-century commercial architecture: marble staircases, ornate ironwork, neoclassical sculptures, and a glass roof that floods the space with light. Designed by architects Jean-Baptiste Buron and Hippolyte Durand-Gasselin, it was one of the first covered arcades in France outside Paris. The boutiques within are worth browsing — artisan jewellery, local designers, an excellent chocolate shop — but the real attraction is the architecture itself. Free, always open. Allow 30 minutes (longer if shopping).
5. Jardin des Plantes
This 7-hectare botanical garden, established in 1807, is one of the finest in France. It contains over 10,000 plant species, magnificent Victorian greenhouses, a Japanese garden, and a series of whimsical topiary sculptures by children's author and illustrator Claude Ponti — look for the giant reclining bench shaped like a gardener and the oversized flower pots with legs. The benches are made from recycled materials, a nod to Nantes' green credentials. The garden's collection of magnolias and camellias is particularly renowned. Free, open daily 08:30–20:00 (winter hours vary). Allow 1–2 hours.
River & Water Experiences
6. Erdre River Cruise
The Erdre is often called France's most beautiful river, and the stretch that runs through Nantes justifies the claim. Bateaux Nantais operates 1.5-hour cruises from the city centre, passing 18th-century châteaux, wooded banks, and the Île de Versailles (a Japanese-inspired island garden). The commentary is in French, but the views need no translation. Cruises run April–October, EUR14–16. Alternatively, rent a small electric boat (no licence needed) from Ruban Vert on Quai de Versailles and explore at your own pace. Allow 1.5–2 hours.
7. Loire à Vélo — Cycling the Loire
The Loire à Vélo is one of Europe's great cycle routes, running 900 km along the Loire Valley, and Nantes is a key waypoint. From the city, you can cycle west towards the Atlantic (50 km to the fishing port of Pornic) or east into the Loire Valley proper. The path is well-signed, mostly flat, and largely traffic-free. Rent a bike from Détours de Loire (Rue de l'Héronnière, Île de Nantes) or use the Bicloo city bike-share scheme (EUR1.50 for 24 hours). The 26 km route from Nantes to the charming village of Clisson, through Muscadet vineyards, is a perfect day ride. Allow half-day to full day.
Museums & Culture
8. Musée d'Arts de Nantes
Nantes' fine arts museum, reopened in 2017 after a major renovation, is housed in a striking building that combines a 19th-century Palais des Beaux-Arts with a modern glass extension (the "Cube"). The collection spans from the 13th to 21st centuries, with particular strengths in 19th-century French painting (Delacroix, Courbet, Ingres) and modern art (Kandinsky, Monet, Sonia Delaunay). The temporary exhibitions are ambitious and well-curated. EUR8, free first Sunday of each month. Allow 1.5–2 hours.
9. Cathédrale Saint-Pierre-et-Saint-Paul
Despite the devastating fire of July 2020 (caused by arson, restoration is ongoing), the cathedral remains a Gothic masterpiece worth visiting. Construction began in 1434 and was only "completed" in 1891. Inside, the Tomb of François II and Marguerite de Foix is a Renaissance masterpiece by Michel Colombe (1507), with allegorical figures of the cardinal virtues at each corner. The soaring white stone interior is unlike the darker Gothic of northern France. The cathedral's status changes as restoration progresses — check before visiting. Free entry when open.
10. Le Lieu Unique
A former LU biscuit factory transformed into a cultural centre that epitomises Nantes' creative reinvention. Le Lieu Unique houses a theatre, concert venue, bookshop, bar, restaurant, and a hammam (yes, in a former biscuit factory). The programme is eclectic — experimental theatre, world music, art exhibitions, philosophical debates. The bar is worth visiting even without a ticket to an event, for the building itself and the atmosphere. Located near the train station.
Day Trips from Nantes
11. Clisson & the Muscadet Vineyards
The village of Clisson (30 min by train) looks like it was transplanted from Tuscany — Italianate architecture, a ruined castle overlooking the Sèvre Nantaise river, and a setting among Muscadet vineyards. The 19th-century sculptor François-Frédéric Lemot, who owned the castle, rebuilt the town in Italian style after the Vendée Wars destroyed much of it. The result is uniquely beautiful. Wine tastings at Domaines de la Bretonnière or Château du Coing. Allow a full day combining wine and architecture.
12. Pornic — Atlantic Coast
The fishing port of Pornic (45 min by train) offers a complete change of scene: a medieval castle overlooking the harbour, a sandy beach, cliffside walks, and excellent seafood restaurants. The coastal path (sentier des douaniers) leads to hidden coves and dramatic views. It's a perfect summer escape from the city, or a bracing winter walk followed by oysters and Muscadet. Allow half-day or full day.
