Nantes is not a stopover on the way to Paris — it is one of the most alive cities in France. A 12-metre electric mechanical elephant that carries 49 passengers and sprays water from its trunk is one of the experiences you will not find anywhere else on earth. Add a ducal castle that once housed French royalty, arguably the most beautiful Victorian arcade in Europe, and a botanical garden where something is always in bloom, and Nantes will surprise you at every turn.
#1 Les Machines de l'île
An art-and-machine project inspired by the work of Jules Verne and Leonardo da Vinci. The electric mechanical elephant stands 12 metres tall, weighs 48 tonnes, carries 49 passengers at a time, walks under its own power, and sprays water from its trunk. Beyond the elephant, there is a Grand Carrousel of giant sea creatures and a gallery of mechanical animals that stops adults and children alike. This is one of the most genuinely singular attractions in the world.
- Book tickets online in advance — the elephant sells out every session, especially during public holidays and summer.
- Elephant rides last 45 minutes per circuit. Check the schedule on lesmachines-nantes.fr before you go.
- The combined Pass Machines covering the elephant and the Grand Carrousel costs less than buying both separately.
#2 Château des ducs de Bretagne
The historic heart of Nantes. Built in the 13th century as the seat of the Dukes of Brittany before the duchy merged with France, the castle later hosted Louis XII and François I. Inside, a city history museum traces Nantes from the medieval period through the industrial age. The inner courtyard is free to enter, and the rampart walk delivers a full 360-degree view over the city.
- The inner courtyard (cour intérieure) and rampart walk are free every day. The museum inside charges €8–10.
- Walk the full circuit of ramparts — the view of the Cathédrale Saint-Pierre bell towers in afternoon light is worth the climb.
- On summer evenings from around 22:00 to 23:00, projection mapping illuminates the castle walls in striking fashion.
#3 Passage Pommeraye
A Victorian shopping arcade built in 1843 and listed as a French national historic monument. Set across three levels on a sloped site, it connects the floors with curving marble staircases and dozens of neoclassical sculptures. The arched glass roof channels natural light beautifully through each level. Director Jacques Demy used it as a filming location for Lola. Today it holds designer boutiques and a classic tea room.
- Entry is free at all hours, but before 10:00 the natural light through the glass roof is at its best for photography.
- The tea rooms and pastry shops inside carry a special item — try the Petit Beurre biscuit in its original Nantes form.
- Come for the architecture rather than the shopping. Most stores are mid-to-upper-range local brands.
#4 Jardin des plantes de Nantes
One of the finest botanical gardens in France, founded in 1807. Spread across 7 hectares, it holds more than 10,000 plant species. The garden is known for some of Europe's largest Magnolia grandiflora specimens and a large glasshouse collection of cacti and tropical plants. Fountain walks, sculptures, and quiet green corners make it a genuine refuge — for locals and visitors alike.
- Free entry year-round, open every day with no closures — exceptional value.
- Spring (March–May) is peak magnolia season; the blooms photograph beautifully in morning light.
- The cactus and tropical plant glasshouses (Serres Tropicales) open in the mornings only — check the schedule before visiting.
#5 Cathédrale Saint-Pierre-et-Saint-Paul de Nantes
A Gothic cathedral that took 457 years to build (1434–1891) and stands 37.5 metres to the vault — 4 metres taller inside than Notre-Dame de Paris. Stained glass from multiple eras, including contemporary work installed after a 1972 fire, fills the interior with changing colour all day. The tomb of François II, Duke of Brittany, and his wife is considered one of the finest Renaissance sculpture works in France.
- Free entry, open daily 08:00–19:00. Morning light through the east-facing stained glass is the best time to visit.
- Do not miss the Tombeau de François II on the lower right of the nave — it is a genuine Renaissance masterpiece.
- Bell tower access requires a special guided tour that runs on a limited schedule; check ahead if you want the city view from the top.
#6 Île de Nantes
A former industrial island and shipyard transformed into Nantes's most energetic creative district. Beyond Les Machines de l'île, which sits here, the island holds the LU arts centre (the former Lefèvre-Utile biscuit factory), designer restaurants in the riverside Hangar buildings, the Prairie de Mauves park, and a constantly changing collection of outdoor art from artists worldwide. It is the place to walk, cycle, and read what contemporary Nantes looks like.
- Rent a Bicloo city bike from any of the docking stations on the island — inexpensive, app- and card-friendly, and you can cover the island comfortably in 2–3 hours.
- Hangar à Bananes along the waterfront converts to popular bars and restaurants in the evening, with live music on some nights.
- Voyage à Nantes, an outdoor arts festival, runs July–August and fills the island with temporary installations.

Before You Pack
Nantes is pleasant year-round, but May through September offers the best weather. Budget at least 2 full days to cover Les Machines, the castle, and the island district properly. If you have a third day, join the Loire à Vélo cycling route along the river for a full day of riding through the Loire Valley.
