In this article you’ll find the best things to do in Nantes, one of those cities many people overlook when planning a trip to France, but that surprises when you get to know it up close.
Located in the west of the country, on the banks of the Loire, Nantes has a good mix of history, contemporary art, green spaces, and neighborhoods with character, and plenty of cultural offerings that make it different from other French cities.
Here you’ll find practical tips and real recommendations to help you organize your visit to Nantes according to your travel style. And if you’re traveling with family, want to get around without spending too much, or only have one day to explore the city, this guide will help you make the most of your time without missing the highlights.
We visited Nantes as part of a route through France, traveling with our children, who loved the city (especially on the Machines Island), but it was a trip we parents enjoyed too. Beyond the family activities, there’s a lot to see, walk, and discover.
If you’re putting together an itinerary for the Loire region or enjoy discovering different cities, it’s worth giving it at least a couple of days. Here I’ll cover the most important sights in Nantes, along with some tips that can help if you’re traveling with kids or trying to get around without spending too much.
💯 If you want to keep exploring this area of France, you can combine your stop in Nantes with a 3-day Loire castles route. It includes a map, practical recommendations, and the most important castles to visit without wasting time.
Map: Things to do in Nantes and How to Get Around
With a full day is enough to see Nantes’ main attractions if you keep a good pace: you can visit the castle, stroll through the historic center, walk along the green line, explore Les Machines de l’Île, and finish up in a park or on a terrace. If you’d like to visit museums or take things more slowly, plan for two days.
Also, most tourist spots are within easy walking distance, especially in the city center. The green line painted on the ground guides you along the whole route. Still, if you need to travel farther, public transport is excellent.
What is Nantes’ Green Line?
The Green Line (“Le Voyage à Nantes”) is a line painted on the ground that runs through the city and connects the main tourist sites, from historic monuments to contemporary art installations. It’s designed so visitors can follow it on foot and discover everything to see in Nantes without a map or GPS.
📌 Tip: if you don’t look closely, you might miss it, because it isn’t marked with signs, only by the green line painted on the ground.
Starts (or ends) near the train station and passes through places like:
- the Castle of the Dukes of Brittany
- the Cathedral
- the Miroir d’Eau
- the Botanical Garden
- the Passage Pommeraye
- the Bouffay district
- the Island of Nantes
- and many public artworks installed along the way
The good thing is that it changes every year, especially in summer, when the “Voyage à Nantes” festival is held. New installations, cultural programs, and ephemeral street art are added to the streets.
💡 Ideal for exploring the city on foot with a through-line, discovering street art, and making sure you don’t miss the main sights. The route is over 12 km, but you can do it in sections. There’s an official Voyage à Nantes app with the updated route and descriptions for each stop.
📷 Book the Nantes guided tour: a good way to start exploring the city, learn its history, and not miss the details of the castle, the cathedral, or the historic center.
Is the Nantes Pass worth it?
The Nantes Pass is often a convenient option for those who want to make the most of their visit. It includes free admission to more than 50 museums and major attractions, such as the Castle of the Dukes of Brittany and Les Machines de l’Île, as well as boat tours and unlimited public transport within the city and to the airport. It also offers discounts at shops and restaurants.

1. The Machines of the Isle (Les Machines de l’île)
An attraction that delights both adults and children, and is definitely a must-see in Nantes. It’s a creative, interactive space inspired by the world of Jules Verne (born in the city) and the designs of Leonardo da Vinci, where everything revolves around giant mechanical animals.
Although each activity may have a fee, there are combo and family tickets available at discounted rates.
a) The Great Mechanical Elephant
The main attraction is the mechanical elephant, a 12-meter-tall structure that walks around the site, moves its trunk, and sprays water at onlookers. There’s no need to climb aboard to enjoy it: you can follow its whole route from the ground, and children love standing in front of it to get splashed.
Practical info for riding the Grand Éléphant: adult general fare is €12. The fare for children aged 4 to 12 is €8. Children under 4 ride free.
b) The Grand Marine World Carousel
Besides the elephant, inside the enclosure is the Carousel of Marine Worlds, a kind of three-level merry-go-round filled with creatures from the sea floor. Each level has different attractions and many are interactive: move a turtle’s head, make a fish fly, or operate a monster’s tentacles. It’s a detail that makes the experience even more fun.
- On the lower level (semi-underground), most structures are closer to the ground.
- On the middle level, some machines are suspended in the air.
- On the top level, there are open views of the Loire and more articulated machines.
⚠️ Some levels have height restrictions (for example, the middle level doesn’t allow children under 1.35 m).
Visitor information for the Grand Carousel (Fair Mode): the regular adult ticket is €12. The ticket for children ages 4 to 12 is €8. Children under 4 enter free. Opening hours are Wednesdays from 2:00 PM, Saturdays and Sundays, and during school holidays. The rest of the time it’s in Discovery Mode, which is another way to visit the carousel.
c) Machines Gallery
The Machines Gallery is the covered area where many of the mechanical creatures that make up the Les Machines de l’île universe are displayed. It’s set up like a working workshop, where you can see machines in development, prototypes, and articulated structures that are activated during the visit.
The tour is guided (also available in French or English), and the most interesting part is that visitors are shown how the machines work, what systems they use to move, and how they’re designed. There’s interaction: at several points during the tour, staff invite visitors to climb on or operate the pieces.
If you like behind-the-scenes looks or want to see how the giant animals are built, this part of the complex is worth a visit.
📌 Tip: it’s not the most entertaining for very young children, but for curious kids (or adults with a curious streak) it’s a great addition to the visit.
Visitor info for Galerie des Machines: the general adult ticket costs €12. The ticket for children aged 4 to 12 is €8. Children under 4 enter free. This ticket also grants a €2 discount on the Carrousel des Mondes Marins, valid for 48 hours.
2. Castle of the Dukes of Brittany
Located in the heart of the city, the Castle of the Dukes of Brittany is one of the most important landmarks to see in Nantes. It was the ducal residence from the 13th to the 16th century and later served as a barracks, a prison, and now a museum. The good news is that much of the castle can be visited for free.
Access to the inner courtyard is free, as is the walk along the ramparts, which offer good views of the moat, the towers, and the town roofs. If you have limited time or don’t want to pay for entry, you can explore those areas without any problem, and the visit is already worthwhile.
📌 Tip: if you’re visiting with kids, the castle grounds provide plenty of space for them to walk and explore safely. The moat often has ducks and vegetation.
If you decide to enter the museum, you’ll find a comprehensive exhibition on the history of Nantes: from the medieval period to 18th-century slave ships and the Nazi occupation. It’s modern, clearly signposted, and includes interactive features.
Visitor information for the Nantes Castle Museum: general adult admission is €9. Visitors under 18 enter free. The museum and temporary exhibitions are free on the first Sunday of each month (except July and August) and during Heritage Days, the Night of the Museums, and VAN Night.
On a plaza in front of the Castle of the Dukes of Brittany you’ll find the Miroir d’Eau, a shallow water mirror of about 1,300 m² with a thin layer of water over granite slabs that reflects the castle. It also features water jets, misting nozzles, and lights that operate day and night, making it a popular spot for kids to cool off, especially in summer.
If it’s summer and you’re traveling with children, remember to bring an extra change of clothes.
3. La Tour Bretagne
It’s the city’s tallest skyscraper, right in the center, very close to the castle. From the top you can access an observation deck with panoramic views of Nantes, where the Le Nid bar is located, decorated with a huge stork and giant eggs.
It’s a good idea to check if it’s open before you go. There’s an admission fee.
From the top, when it’s open, you can go up to the Le Nid bar, which has a terrace with panoramic views of Nantes. The tower is 144 meters tall and has 32 floors, and although the building itself is used for offices, the main attraction is the view from above.
Important: in recent years it has been closed for maintenance or renovations at various times, so it’s best to check if it’s open before you go. If it’s operating, access to the viewing platform usually requires a nominal fee.
4. Cathedral of St. Peter and St. Paul
A few steps from the castle, the Cathedral of Nantes stands out for its white façade and impressive height. It’s a Gothic building that took more than 400 years to build, with details dating from the 15th to the 19th century.
Admission is free, and inside it’s worth seeing the bright interior, the organ, the stained-glass windows and, above all, the tomb of Francis II of Brittany and Margaret of Foix, the parents of Anne of Brittany. The funerary monument is one of the most important works of Renaissance art in France.
5. The Bouffay neighborhood
The Bouffay neighborhood is Nantes’ old town. It features cobblestone streets, terrace-lined squares, medieval facades, and plenty of bars and restaurants. It’s one of the liveliest areas in the city, both day and night.
It’s ideal for wandering without a plan, discovering historic corners, and stopping for a bite. Expect to see half-timbered houses, small galleries, souvenir shops, and cafés with outdoor seating. It’s also where fairs or street performances often take place, especially in summer.
📌 Tip: if you’d like to try crêpes or a Breton galette, this is one of the best places to do it.
6. Squares and streets in central Nantes
Besides Bouffay, the center has other areas worth exploring in Nantes. If you follow the green line or just let yourself wander, you’ll pass by several photogenic spots with a local vibe:
- Place Royale: one of the city’s larger squares, with a central fountain and surrounded by classic buildings. A great spot to take a break.
- Place Graslin: elegant, dominated by the impressive Théâtre Graslin in the background and several cafés with terraces.
- Passage Pommeraye: a 19th-century shopping arcade with staircases, stained glass, and period details. Very photogenic.
- Rue Crébillon, the street that links Place Royale with Place Graslin, known for its elegant shops and a slightly Parisian air. Ideal for a relaxed stroll, window-shopping, or hunting for a local boutique.
📌 Tip: these areas have more of a shopping and classic café scene, and contrast with Bouffay’s more laid-back character.
7. Île de Nantes
The Île de Nantes is a large island in the middle of the Loire that’s undergoing a major transformation. Where industrial areas once stood, you’ll now find cultural spaces, street art, modern architecture, and plenty of local life. Besides Les Machines de l’Île, which are the area’s main tourist draw, it’s worth taking some time to explore the island’s other corners.
There are outdoor artworks, permanent and temporary installations, and zones where port cranes have been repurposed as sculptures. You’ll also find parks, pedestrian walkways, and new buildings that contrast with the old industrial sheds. If you like contemporary art or photographing offbeat places, this walk is for you.
📌 Tip: walk along the Loire riverbank and cross one of the pedestrian bridges to see the city from a different angle.
8. Jardin des Plantes
The Jardin des Plantes is a large, well-kept green space just a few minutes’ walk from the castle or the train station. It has shaded paths, hidden sculptures, play areas for kids, benches for picnics, and a wide variety of plants and trees, making it one of the best spots in Nantes to relax.
If you’re traveling with family, it’s a great stop: the little ones can play in the sand, run around safely, and see animals like ducks. There are also public restrooms and drinking fountains. For travelers without children, it’s a quiet place to rest for a while, read, or just take a break after so much walking.
📌 Tip: it’s not a classic botanical garden with labels and explanations, but rather an urban park with artistic touches and themed areas.
9. Le Lieu Unique
Le Lieu Unique is right next to the train station, a few blocks from the castle. It’s the former LU cookie factory, which was converted into a cultural center.
Today it serves as an exhibition space, bar, restaurant, bookstore, and events venue, with a fairly alternative program. It also has a decorated tower that dates back to the original factory and is one of the most recognizable features of the skyline.
📌 Tip: if you’re short on time or not interested in contemporary art, you can just go in, admire the building, and grab a drink at the bar, which has a nice atmosphere.
Useful information for visiting Nantes
Getting around Nantes: Free tram
On weekends, the tram is free. This is handy if you’re staying a bit farther from the center or want to explore without spending on transportation.
Is it a city to visit with kids?
Yes, it’s a very family-friendly city. The mechanical elephant at Les Machines de l’île is one of the main attractions to see in Nantes with kids. There are also parks with playgrounds, striking street art, and a free tram to get between spots if you don’t feel like walking anymore.
Where to eat in Nantes?
After so much walking, nothing beats ending the day with a good crêpe. There are plenty of creperies in the center, but one we really liked was the Crêperie Le Milan & Le Rossignol, near the historic center. The atmosphere is simple, but the service is good and the ingredients are fresh.
We tried a vegetarian crêpe with creamed spinach, goat cheese, cheese, and walnuts that was delicious and I want to recommend it, another that had sausage, and for the kids we ordered the crêpe classic ham and cheese, which never fails. Perfect for a quick, tasty meal that won’t break the bank.
We also tried to visit La Cigale, a well-known Art Nouveau brasserie that’s a must-see in Nantes, but if you go before 3 p.m. they won’t let you in just to have a coffee. It’s best to go later or make a reservation if you want to get in.
