As part of Corsica’s Gulf of Porto UNESCO World Heritage Site, Les Calanques de Piana (Calanche di Piana in Corsican) is a world of eerie geologic formations, high cliffs, red granite columns and spectacular sea caves and arches. On the mountainous drive from Ajaccio to the fishing village of Porto, you’ll observe eagles and falcons, while boat tours allow you to get up close to cormorants, nesting osprey and, if you’re lucky, a pod of dolphins in the clear waters.
