Nantes is often thought of for its industrial history or its festivals, but the city offers an exceptional setting for a stay focused on well-being and urban nature. As a local, I prioritize vast green spaces and places where one can truly disconnect from the hectic daily rhythm. This guide offers a concrete selection of spots accessible by foot or tram, perfect for a "gentle thermalism" weekend combining botanical walks and relaxation moments.
Jardin des Plantes
It is undoubtedly the green lung of the city center. With over 10,000 plant species, it’s the perfect spot for a slow morning walk. The paths are wide, shaded by century-old trees, and the atmosphere is peaceful despite its proximity to the city center. I particularly recommend visiting the tropical greenhouse for an immediate change of scenery.
Les Machines de l'Île
Even though it’s not a spa, the sensory experience offered here is unique. Riding the Grand Mechanical Elephant or sailing on the Carrousel of Marine Worlds provides a form of active meditation. The rehabilitated industrial architecture of the former shipyards creates a timeless backdrop that encourages mental disconnection. Be sure to book in advance, especially on weekends.
Château des ducs de Bretagne
The castle itself is impressive, but it’s especially its surroundings that matter for our relaxation itinerary. The dried moats have been transformed into beautiful landscaped gardens. Walking the complete circuit of the ramparts offers a panoramic view of the city and allows for a physical and mental uplift. It’s a historic place that breathes serenity as soon as you move away from the main entrances.
Jardin Extraordinaire
Located near the train station, this garden surprises with its modern and minimalist design. Less dense than the Jardin des Plantes, it invites contemplation with its ponds and subtle water features. It’s a perfect spot for a reading break or a nap on one of the strategically placed benches facing the natural elements. Accessibility is total, making it an easy stop during an urban journey.
Île de Versailles
This island in the middle of the Erdre is a true haven of peace. It is easily accessible and features lush vegetation, tree-lined paths, and a very subdued atmosphere. It’s the perfect place to observe birds or simply listen to the sound of water. In the evening, the discreet lighting adds a romantic and soothing dimension to the walk.
Aquatonic Nantes
For the "thermalism" part itself, Aquatonic is a must-visit. Located in the city center, this wellness space offers thermal pools, spas, and hydromassage circuits. After a day of walking, diving into the warm waters effectively relaxes the muscles. The atmosphere is calm, designed for relaxation rather than partying.
Parc de Procé
A bit more remote, Parc de Procé offers a wilder and woodier setting. It’s an old private estate turned public park, with large grassy areas and undergrowth. Ideal for those looking to escape the hustle and bustle of the city center while still staying in Nantes. The rose garden is particularly beautiful in spring, offering a colorful and fragrant spectacle.
Parc de La Gaudinière
This park located in the south of the city is less known to tourists but highly appreciated by locals. It features a large lake, sports fields, and well-maintained green spaces. It’s a great place for gentle sports walking or family picnics. The lack of excessive crowds makes it a good compromise for enjoying nature without being isolated.
In Practice
To travel between these locations, the TAN network (Transports de l'Agglomération Nantaise) is very efficient. The tram serves most key points: line 1 for the Jardin des Plantes and the Château, line 2 for Les Machines de l'Île and Aquatonic. For more distant parks like La Gaudinière, the bus or the bike-sharing service (VeloCite) are recommended.
Most parks open early in the morning (around 8:30 AM) and close late in the evening (until 10:30 PM depending on the seasons), allowing for total flexibility. For Aquatonic, it is highly recommended to book your session online to secure a time slot, especially on weekends. Wear comfortable shoes for the botanical visits and don’t forget your swimsuit for the thermal finale.
