Cruise across the Marmara Sea for a day spent in the waterfront idyll of Büyükada, the largest of the Princes' Islands. Take a horse-drawn carriage ride along car-less streets to see colorful mansions, enjoy a seafood lunch, and soak up the scenery from a picturesque ferry ride.

After you're picked up from your hotel, head down to the ferry docks and board a vessel for the lovely cruise out to the Princes' Islands, catching glimpses of Leander's Tower and Istanbul's seaside landmarks along the way. Approach the pretty 19th-century ferry terminal of Büyükada and disembark, enjoying the pleasant, old-timey atmosphere of an island with no motorized vehicles.

Jump in a horse-drawn carriage for a perfectly era-appropriate way to explore the island's Ottoman-Victorian architecture and major landmarks. See the beautiful Hagia Yorgi church, the clock tower, and flower-filled gardens before heading to the waterfront to savor a seafood lunch with a view. After lunch, continue exploring, climbing up the hilltop Greek Monastery of St. George, and learning about the island's past before heading back to the ferry for your evening return to your hotel.
