In the heart of the Mediterranean sea, The Explorers overflows Corsica's mountain island, bordered with a 621 mile (1,000 km) turquoise water shoreline. Its landscape variety: the Agriates desert, the Balagne, the Calanques of Piana, high lakes and immaculate beaches. Located at the crossroads of major maritime routes, its perched villages, watchtowers and citadels testify to its resistance to invaders.
