Sailing from the Indian subcontinent over to the Horn of Africa, exploring the Yemen or the lost city of Petra emerging from its red rock surroundings, this is an escape that skirts the modern world and takes you, instead, to cities that bustle and trade as they have done for centuries. Red Sea and Black Sea link with the Med, taking you to Crusader coasts, Aegean islands that retain their bohemian charms and Renaissance landmarks signed Bernini and Michelangelo.
