About Bonifacio

The old town of Bonifacio stands on white cliffs at the southern end of Corsica, reached through a gate above the harbour. Stairs cut into the rock lead down to the water, and boats leave the port for the Lavezzi islands and the caves below. Sardinia lies a short ferry ride across the strait, and the beaches of the far south stretch towards Porto-Vecchio. Late spring and September are ideal for the sea, summer is hot and crowded, and winter is mild and very quiet.
