Istanbul rewards preparation more than most cities: it is vast, hilly, split by water and layered with two empires' worth of must-sees. This guide skips the poetry (the city supplies its own) and focuses on the practical decisions that make a first visit run smoothly.
Key facts
- Currency: Turkish lira; cards widely accepted, but carry some cash for markets and tea
- Transit: buy an Istanbulkart on arrival — it covers trams, metro, funiculars and ferries
- Best months: April–June and September–October
- Time needed: four days minimum to see both sides of the water without rushing
- Visas: requirements vary by nationality — check the official e-visa site before flying
Choosing where to stay
First-timers face a genuine choice. Sultanahmet puts Hagia Sophia, the Blue Mosque, Topkapi Palace and the Basilica Cistern on your doorstep — unbeatable for sightseeing, quiet at night, and touristy at mealtimes. Beyoğlu and Galata, across the Golden Horn, trade proximity for atmosphere: rooftop views, nightlife, cafés and the feel of a living city. Kadıköy, on the Asian side, suits repeat visitors and food lovers happy to commute by ferry. Our honest advice for a first trip: sleep in Beyoğlu, sightsee in Sultanahmet.
Getting around
Load an Istanbulkart at any machine and the city opens up. The tram line through Sultanahmet links most of the headline sights; funiculars conquer the steepest hills; and the commuter ferries between Europe and Asia are the best value sightseeing in the city — a Bosphorus crossing for the price of a transit fare. Traffic is heavy, so default to rails and water over taxis whenever possible.
Planning the big sights
Cluster the giants: Hagia Sophia, the Blue Mosque, the Basilica Cistern and the Hippodrome sit within a short walk of each other, with Topkapi Palace adjacent — but do not attempt all of them in one day. Two sights a day, mornings for the most famous ones, is the sustainable pace. Book timed tickets online where offered, and check current opening days, since some sites close one day a week.
