WARNING ADULT CONTENT!
A small path leads to the semi-secluded clearing near a bird reserve in the Bois de Vincennes park, where about 10 naturists were enjoying a sunny afternoon on the grass.
Nudists have long demanded to have their own green spot in the French capital.
More than 400 naturist beaches and camp sites exist in France, where more than 2.5 million people practice nudism.
The mayor's office said the creation of a nudist area, though still in an experimental stage, is "part of an open-minded vision for the use of Parisian public spaces".
In Paris, one public pool allows nude swimming three times a week.
A sign warns park-goers of the nudist section in Bois de Vincennes.
The space will be open until October 15th from 8am to 7.30pm.
