Take a break from sightseeing in the morning and enjoy a Bosphorus and Black Sea cruise from Istanbul. You'll be picked up from your hotel and taken to the port, where you'll set off to discover the coastal views of Europe and Asia from the water. You'll have the opportunity to savor a mezze lunch as you sail. Look out for landmarks like the Galata Tower and Bosphorus Bridge, and, if time allows, stop off at Poyrazköy to swim in the Black Sea.
