İstanbul travel guide

The best Istanbul plan leaves time for a few neighbourhoods instead of trying to finish the whole city. Add ferry journeys and everyday-life pauses between historical visits.

🏛️ Avoid stacking too many sights into one day on the historic peninsula.

⛴️ Treat a ferry ride as a chance to see the city from the water, not just as transport.

☕ Give Kadıköy and Moda their own time for streets, cafés and the waterfront.

💡 Crowds and journeys across the city can be tiring, so group each day around nearby neighbourhoods.
