Bonifacio, Corsica, France

Bonifacio, a dramatic clifftop citadel guarding the southernmost tip of Corsica, exudes a spellbinding aura. Picture a labyrinthine town sculpted from honey-coloured limestone, its ramparts clinging precariously to sheer white cliffs that plunge into the cerulean Mediterranean. Wander through a maze of narrow streets, each turn revealing breathtaking panoramas of the Bonifacio Strait and the distant shores of Sardinia. History buffs will revel in the imposing Bastion de l'Etendard, a 13th-century fortress. Descend the legendary Escalier du Roi d'Aragon, a 187-step stairway carved into the cliff face, promising a truly unforgettable experience.
