Champigny to Nogent via the Ile Fanac and the Jardin Tropical
The Marne near Joinville is the perfect choice for a town-dweller’s autumn stroll, combining the glowing colours of the trees reflected in the water with quick and easy access to Paris. You can shorten or lengthen your walk at whim, as you are never far from a station on the express RER A line.
Since the 19th century this picturesque part of the Marne has been a traditional playground for Parisians as well as locals at weekends, with several famous boating clubs and guinguettes (riverside restaurants with a dance floor and accordion music) still operating along its banks. Joinville is also famous for the cinema studios where several landmark French films were made in the 1930s and 40s.
But what is surprising about this popular and generally tidy part of the river is the survival of two little pockets of greenery where nature has been allowed to flourish more or less unchecked. I knew about the quietly decaying Jardin Tropical hidden on the edge of the Bois de Vincennes, but I didn’t realise how close it was to the Marne until I took this walk. Nor had I ever visited the tiny and surprisingly rustic Ile Fanac, although it is easily accessed by steps down from the Pont de Joinville. I just hadn’t noticed them, assuming that the island was only accessible by boat.
You could easily do the 4½ km riverside walk from Champigny to Joinville without making either of these two detours, perhaps combining it with lunch at La Mascotte riverside restaurant en route. But if you enjoy off-beat discoveries, the Ile Fanac will add another kilometre to your walk if you return from Joinville station and the Jardin Tropical a further 2½ km, returning from the station at Nogent sur Marne.
8 km walk from Champigny to Nogent, via the Ile Fanac and the Jardin Tropical
From Champigny RER station take the exit for the bus station and cross at the pedestrian crossing facing you. Take the quiet Rue St Benoit ahead, slightly to your left, and follow it to the end, where you will see the Marne. Turn right to go down to the towpath and then left to follow it under the Pont de Champigny for just over 2 km. The path here is prettier and closer to the water than on the other side.
Just before the next bridge, the Pont du Petit Parc, look for the steps leading up to it and cross to the other side of the river. More steps lead down onto the Quai Gabriel Peri. Turn right to follow the river for less than a kilometre to the next bridge, the Pont de Joinville.
Just before the bridge you will pass the riverside terrace of La Mascotte, a restaurant overlooking the boats moored at the Port de Joinville. I had quite a good couscous lunch here one Sunday, although the overworked waiter served it with the absolute minimum of ceremony and on another occasion we had to wait a long time for the coffee we had ordered. But it is so rare to find an unpretentious café-restaurant overlooking the river near Paris that La Mascotte is deservedly popular.
Soon afterwards you will pass the former Pathé film studios, with a sign explaining that they were built by Gustave Eiffel in 1906. Marcel Carné’s Les Enfants du Paradis, arguably one of the finest French films ever made, was completed here in 1944.
After passing the studios return to the riverside path and continue under the Pont de Joinville, where you will find an unobtrusive set of steps leading up onto the bridge.
Steps down from the bridge on the right lead to the tiny Ile Fanac, alongside a lift installed in 2011. You will find yourself in a little park with a useful map displayed nearby. Turn right to follow the riverside footpath around the island.
The Ile Fanac is only 600 metres long and a mere 100 metres wide, containing just 32 buildings mostly hidden by trees, and has around 100 residents, many of them artists. Cycling is not permitted and there are of course no cars.
It has been inhabited since the 19th century and was the site of the first rowing club in France, the Club Aviron Marne et Joinville, built in 1883 and still there, although the building is a reconstruction dating from 2007 after a fire destroyed the original. But the most iconic building is the former Maison Fanac on the west bank (lead photo) from which the island takes its name. It once housed a popular guinguette called ‘Chez Jullien’, vividly described by Zola in his novel Au Bonheur des Dames, 1883. It was saved from demolition in the 1960s and now houses the Ecole Municipale des Arts (music and dance).
Apart from its two boating clubs and the Ecole des Arts, the island is exclusively residential. In the 1960s its future was threatened by a plan to turn it into a sports complex. As a result it was declared a conservation area in 1965 and the entire island is now protected from development, with environmentally sensitive measures taken to prevent erosion of the banks and flooding.
You can follow the footpath right round the island, including the overgrown northern tip where another guinguette used to stand, past houses half hidden by gardens, some with enviable little jetties.
Leave the island by the steps from which you arrived, and continue to the other side of the bridge.
If you decide to end the walk at this point, take the right hand side of the busy uphill road which is a continuation of the bridge, the Rue Jean Mermoz, and turn right at the end into the Avenue Jean Jaurès for the RER station at Joinville le Pont.
To continue the walk, turn right from the bridge to follow the towpath for another 2 km to Nogent. You might pass an occasional fisherman or canoe but the setting becomes steadily more urban and eventually you will have to leave the towpath. Continue to follow the river until you come to a little bandstand. I can recommend it as a useful shelter if you are caught in a shower, as I was.
Opposite the bandstand on the other side of the river, you can see the gigantic sign for Chez Gégène, the doyen of the guinguettes still operating on the Marne and something of an institution.
With your back to the bandstand take the right hand side of the Avenue Franklin Roosevelt in front of you, continue across the Avenue Charles V and up the steps ahead of you. Follow the footpath to the Avenue Watteau, past a discreet sign relating that a château given by Charles VII to his mistress Agnès Sorel in 1444 once stood here, demolished around 1626.
Cross the main road ahead, the Avenue de Joinville and continue straight over into the quiet Avenue des Chataigniers, where you will see a signpost for the Jardin Tropical. The first turning on your right, the Avenue des Marronniers, leads to the RER station of Nogent sur Marne.
Continue along the Avenue des Chataigniers to the end and cross the road to arrive at the Jardin d’Agronomie Tropicale in the Bois de Vincennes facing you. A faded red Chinese archway decorated with dragons and phoenixes marks the entrance to the 4½-hectare park within a park.
To the right of the archway you are in Asia, to the left in Africa, but it won’t take very long to make a circular tour of the park which will bring you back to your starting point.
The site was originally created in 1899 for the scientific cultivation and study of rubber, coffee, cocoa, banana and vanilla plants, which were then sent to the French colonies in Africa and Asia to improve the crops being grown there. In 1907 Tuareg, Indo-Chinese, Madagascan, Congolese, Sudanese and New Caledonian ‘colonial villages’ were recreated in the Jardin Tropical for the ‘Exposition Coloniale’ which attracted two million visitors between May and October. The decaying pavillons dotting the park today are the remnants of these artificial villages.
During the First World War soldiers from the colonies were treated in a hospital in the Jardin Tropical, a mosque was built there (no longer standing) and after the war memorials to those who died fighting for France were put up. They were covered with flowers on my most recent visit, just after 11 November.
The site was used by various horticultural research centres until 1995 but tropical plants were no longer grown there. The abandoned buildings continued to decay and some were vandalised.
In 2003 the site was acquired by the City of Paris and has been open to the public since 2006, although not many people seem to know about it. It is listed as of historical significance but until quite recently a general air of neglect pervaded the whole place. There has been some attempt to make more of the site, with detailed explanatory notices and a general tidying-up, and further restoration is planned. But it has retained its slightly melancholy and mysterious atmosphere, especially on weekdays when it is almost deserted.
Return from the main entrance back along the Avenue de Chataigniers and turn left into the Avenue des Marronniers to find the RER station at Nogent sur Seine on the right.
RER A trains to Boissy St Leger from Châtelet-Les Halles run every 10 minutes or less and take 21 minutes to Champigny. The return journey from Joinville le Pont is at the same frequency and takes 15 minutes; trains from Nogent sur Marne take 13 minutes. Details
