Gorges: Gorges du Verdon, Gorges du Nesque, Col de Tempêtes and Mont Ventoux. Distance: 320km. Gorges du Verdon Day 6 finds me starting my day in Saint-André-Les-Alpes at the head of Lac de Castillon, fed by Le Verdon River which over the millennia has gouged out Europe’s version of the Grand Canyon.
