Istanbul, a vibrant metropolis that straddles both Europe and Asia, is Turkey’s largest city with a population of over 15 million. It’s a cultural and historical hub where Roman, Byzantine, and Ottoman influences blend seamlessly with modern Turkish life. The official language is Turkish, but English is commonly spoken in tourist areas, restaurants, and shops. The local currency is the Turkish Lira (TRY), and while credit and debit cards are widely accepted, it’s useful to carry some cash for small vendors and taxis. Istanbul operates on Turkey Time (TRT), which is GMT+3. Cruise ships usually dock at the newly redeveloped Galataport in the Karaköy area, a modern and tourist-friendly terminal equipped with customs, shopping, dining, and easy access to transport. From the port, you can walk, take a tram, or grab a taxi to major attractions like Sultanahmet, Taksim, and the Grand Bazaar. Public transport is efficient and affordable, including trams, buses, ferries, and the metro—using an Istanbulkart offers the best value for multiple rides. Tap water is safe for brushing teeth, but bottled water is recommended for drinking. Istanbul is generally safe, though like any large city, be mindful of pickpockets in crowded tourist spots. The dress code is relaxed, but modest attire is appreciated at religious sites (headscarves are provided at mosques if needed). Most shops and restaurants are open late, and the city comes alive in the evenings with food, lights, and music. With its welcoming atmosphere, layered history, and dynamic energy, Istanbul offers cruise travelers a smooth, culturally rich experience from port to palace.
