On the intermediate terrace, a small stream runs through the forest, descends steeply and then flows into the river.
It is at the foot of this small waterfall that these hunter fishermen installed their summer dwellings a few thousand years ago. Leaning against the cliff and protected from the prevailing winds, they were only a few steps away from the beach. Nomadic people, they lived by gathering fruits and berries, fishing and hunting.

Dozens of generations enjoyed the resources and proximity of the river every summer.
