Arche de Ponadieu

The waters of the Siagne, sometimes a joyously chaotic spectacle, sometimes spreading out into peaceful, translucent pools (launes), are forced to pass beneath the natural arch known as the Ponadieu.
The deep, ever-present roar of the tumultuous waters of the Siagne can be heard from afar.

The Pont de Ponadieu was created by limestone deposits (tufa) from a now-extinct spring. It is a light rock (used in buildings) that bears impressions of vegetation.

Reaching reach this natural arch requires a walk lasting 45 minutes to an hour (feasible for all). The path goes downhill and leads to a pool beneath this magnificent natural arch that spans the river (1,709 feet/521 meters). The path leading to the Pont de Ponadieu partly runs along the Vallon de la Combe, a particularly agreeable site by virtue of the shade of large holm oaks.
This hike forms a loop that takes approximately 2.5 hours to complete.
Be prepared: the walk back up will be the hardest for your calves!
