Our good deals by department

In Paris (75)

#1. Enjoy the freshness of the trees in Parisian parks

Paris, like all large cities, concentrates heat islands. But the city is adapting and the spaces of freshness are multiplying.

We recommend that you go and cool off lying on the grass, under a hundred-year-old tree, in one of the city's large parks : the Parc Monceau, Parc Montsouris, Parc des Buttes Chaumont, Parc de Bercy or even the very pretty and little-known Parc du Butte du Chapeau Rouge, Bois de Boulogne or Vincennes... The choice is vast!

Psst: some parks and gardens close at midnight to enjoy the evening with your feet in the grass

In Paris, 140 parks are open 24 hours a day, convenient to enjoy the evening and the drop in temperatures before going to bed.

And in the summer, a number of green spaces close their doors later than usual (until midnight) to leave Parisians with the joys of having picnics with their feet in the grass.

#2. Swimming in Paris is possible

From 4 July to 30 August, the Seine opens up to urban bathers at different points along its course: in Grenelle opposite the Île aux Cygnes (15th), at the Quai de Bercy (13th), in the Bassin de La Villette or at the Jules Noël Sports Centre (14th)...

Find the natural swimming spot that suits you best or enjoy one of the many swimming pools in the city.

In Seine-et-Marne (77)

In this green and blue department, between the forest of Fontainebleau, the banks of the Seine or the Marne, there are many options for freshness.

We reveal our best anti-heatwave plans.

Have you heard of Conflans-Sainte-Honorine? Located at the confluence of two rivers, the Seine and the Oise, it is the capital of inland waterway transport (river transport by barge). The boatmen have a chapel (on a barge!) and even a boarding school for their children.

Conflans has a lot to offer the visitor in search of freshness: a medieval castle, chalk cliffs and beautifully landscaped banks of the Seine - large terraces, deckchairs at the water's edge.

It is also a pretext for a beautiful shaded walk along the water, along the historic barges and boats that are moored there.

The Georges Valbon Departmental Park is the largest park in the Ile-de-France region classified as Natura 2000, with its lake and its 400 hectares of meadows and lawns.

And in summer, he plays the aquatic card to the fullest:

  5. Large lawns and playgrounds

So come and sit in the cool for the day, it's totally exotic, in the middle of Seine-Saint-Denis.

What would the Val-de-Marne be without its bucolic banks of the Marne punctuated by legendary guinguettes?

When you feel like freshness, jump on the RER, towards Nogent-sur-Marne, Joinville-le-Pont or Saint-Maur des Fossés for a shaded passeggiata along the water.

In the Val-d'Oise (95)

#1. Romanticism and freshness in Auvers-sur-Oise

Take a seat on line H, direction: the banks of the Oise!

First stop: Auvers-sur-Oise.

The city, famous for having welcomed the brilliant painter Vincent Van Gogh in its last weeks, has a lot to offer to travelers in search of freshness : from the banks of the Oise (with a cute guinguette), to the forest paths, via the park of the Château d'Auvers and the pretty flowered streets: a change of scenery and shade guaranteed!

You can go directly to Auvers by train, via a change at Valmondois. Or add a little extra walk by stopping in Méry-sur-Oise. Towards Auvers, the path goes straight down and on the way you will come across the castle of Méry and its superb park (take a look around).

#2. La Dolce Vita in L'Isle-Adam

A little further on the H line, the charming town of L'Isle-Adam has a lot to offer city dwellers in search of freshness!

Located on the banks of the Oise, the small town unfurls open-air cafés and lawns gently sloping down to the cool waters of the river.

Looking for more freshness: pedal boats are available for rent and for a day like at the beach, the aptly named Plage de l'Isle-Adam offers its very Belle Epoque atmosphere to those who dream of swimming (the pool is superb) and idleness. Be careful, it's paid (but free for children under 5 years old).
