    Be careful!

    Bats take advantage of the natural and artificial cavities of the low Verdon gorges to hibernate. When they fall asleep, their temperature and heart rate drop and their breathing seems to stop (breathing stops can last from 60 to 90 minutes!). An impromptu awakening would condemn them. The flagship Mediterranean species here is Capaccini's Murin, whose large feet allow it to collect insects (and sometimes fry) on the surface of the water.

    Here the little road seems to flow into the lake. It has not always been so.

The 3rd step, easier than the previous one, allows on the heights to easily reach Esparron-de-Verdon and Quinson. The 4th stage, the longest and most technical, rushes into the lower gorges then goes up the left bank of the Verdon on the plateau of Mallasoque.
