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 seasons: 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.

Mosque etiquette

Working mosques welcome visitors outside prayer times. Dress modestly — shoulders and knees covered, headscarves for women (usually available at the entrance) — and remove shoes where indicated. Visits pause around the five daily prayers; midday Friday is the week's main prayer, so plan mosque visits around it.

Bazaars, food and money matters

The Grand Bazaar and the Spice Bazaar are experiences first and shopping second: go to wander, bargain good-naturedly if something catches your eye, and keep valuables zipped in the crowds. Eat beyond the tourist core — a simit from a street cart, a fish sandwich by the water, meze in a backstreet tavern. Tipping around 5–10% in restaurants is customary; small change is appreciated everywhere.

A word on pace

Istanbul is hilly, cobbled and endlessly distracting. Build slack into every day — the unplanned hour in a tea garden or a ferry taken for no reason is usually the memory that outlasts the monuments.

Tip: On your first evening, take any ferry to the Asian side and back around sunset. For a couple of lira you get the skyline — domes, minarets, Galata Tower — burning gold across the water, and the best possible introduction to the city.
