In the middle of a heatwave, the site remains cool and swimming there is a real pleasure; all the more so as it is only accessible after meritorious efforts, given the elevation gain to overcome. To be done on foot or by MTB, and even pushing the bike on certain sections!

Accessible by a wide path that ends in a hiking singletrack along La Brive, itself stepped with several small waterfalls before arriving at the main waterfall after the confluence with the Grand Pertuis stream. Some ruins of what may appear to be a mill. Some traces of dirt from an uneducated, undernourished, poorly dressed, poorly housed, and poorly heated civilization......
