Walk the ceremonial spine of imperial Istanbul: the Sultanahmet (Blue) Mosque with its cascade of domes and 20,000 hand-painted Iznik tiles, the ancient Hippodrome where Byzantine chariots once raced around a 3,500-year-old Egyptian obelisk, and then descend into the Basilica Cistern, a sunken sixth-century forest of 336 columns lit like an underground cathedral with two enigmatic Medusa heads at its feet. Three civilizations, Roman, Byzantine and Ottoman, layered within a 10-minute walk.

Beats the shipThese exact sites form the backbone of the ship's USD 150-200 'Highlights of Istanbul' coach day. On your own the hard costs are tiny (the mosque is free, the cistern under EUR 40) and the walking distances are minimal, so book direct and pocket the difference. The ship tour only earns its markup if you have a very short port call and want the door-to-door coach.
