Drive the scenic roads above Rognac and enjoy stunning views of the Étang de Berre. As you reach the heights, the vast expanse of this lagoon stretches out before you, framed by rolling hills and distant mountains. The shimmering waters reflect the sunlight, creating a breathtaking panorama that is well worth the climb. Don’t forget to pause and admire the scenery before heading back down, enjoying the coastal breeze.

Very nice views, sometimes very rocky; without a mountain bike you have to push a few sections.

The Roquefavour aqueduct is well worth seeing and follows the tradition of Roman aqueducts. It was only built in the 19th century and completed in 1847.
