Cliffs 1000 reflections

Plage de la Mine d’Or, in Pénestin, captivates visitors with its cliffs of golden ochre with changing reflections. This exceptional hue comes from layers of sand and clay rich in iron oxides, compacted hundreds of thousands of years ago. A listed geological site that is unique in Europe, this beach offers an ideal setting for swimming and sunset strolls, thanks to its westerly aspect.

A truly fragile natural area, it invites you to discover it with respect. At low tide, the stretches of sand and geological curiosities are revealed. The beach also becomes a playground for fans of shore fishing. The Mine d’Or beach in Pénestin can be explored all year round, to the rhythm of the tides and the light!
