Verdon (Grand Canyon)

verified Ungraded Low flood risk La Palud-sur-Verdon, Alpes-de-Haute-Provence

Aquatic traverse through the deepest gorge in Europe, no rope work but continuous swimming over four miles of limestone narrows under thousand foot walls.

Couloir Samson is the entry section, commonly run as a shorter rando-aquatique by itself. Griffon vultures nest in the upper cliffs and some side routes have seasonal raptor restrictions; verify with the Parc Naturel office. Wetsuit mandatory, water cold from dam-released depths even in August.
