I don't really known any of the artists playing there or where Rivolet is for that matter.
My hunch told me that a festival named Dindes Folles ('Crazy Turkey') must have a sense of playfulness.
Its founders started back in the 90's with the idea of bringing culture to the countryside.
In bucolic surroundings, a river runs through it, the Dindes Folles offer 3 days of Clowns, Music, Dance and Theater.
No Glastonbury here, no stars, just talented people letting their creative juices flow.
I was told that another French festival with a human face is La Renverse in my native Morbihan, (August 13 and 14) not far from the ocean, 10 artists and bands, 5 per day… plus local beers, crepes, mussels, no junk food it seems.
Neither Dindes Folles nor La Renverse will bust your budget.
(*Note that the sites for both Festivals are in French only)
