Le Vieil Esclangon
Wednesday, July 9 and Friday, August 8
In the heart of the Bès valley, the famous Vélodrome winds its way through an impressive landscape. It’s as you climb up to Vieil Esclangon that it gradually reveals itself, with its rocks rising skywards. When you think that they were born at the bottom of the sea less than 20 million years ago, what a long way we’ve come!
