Our final day, we saved the best for last. The Gorges du Verdon is a natural wonder that needs to be seen to be believed. A gash in the limestone Earth, once an ancient seabed, created over millions of years of active geology. The pale blue vein of the Verdon River carves through the ancient canyon before filling the Lac de Sainte-Croix. We circumnavigated the gorge via the northern and southern rims to take in the entirety of the landscape and give our tired legs one last test.
