A city of 15 million that sits on two continents, split by the Bosphorus strait. The streets mix Roman ruins, Ottoman mosques and modern traffic, and most days involve at least one ferry ride. It feels less like a postcard and more like a living, layered metropolis.

When to go

Spring
April and May bring mild temperatures, around 15-25°C, and tulips planted by the municipality. Tourist numbers are moderate and hotel prices are lower than in summer. This is the season to walk the old city without overheating.
Summer
June to August is hot and humid, often above 30°C, with long days and a busy schedule of festivals. The city fills with visitors, so queues are long and prices at their highest. The Bosphorus ferries offer some relief, but you will sweat between sights.
Autumn
September and October are much like spring: warm days, cool evenings, and a slow drop in crowds after mid-September. This is the best balance of weather and quiet; the sea is still warm enough for a Bosphorus cruise.
Winter
December to February is cold, wet and grey, with temperatures close to freezing. Some restaurants and gardens slow down, but museums stay open and the city is quieter. Cheap flights and hotel deals make it a budget season for those who do not mind rain.

Getting your bearings

The Bosphorus runs north-south, splitting the city into a European and an Asian side. The Golden Horn, an inlet of the Bosphorus, cuts into the European side and marks the old city: Sultanahmet, where Hagia Sophia and the Blue Mosque stand, sits on a hill between the two seas. North of the Golden Horn are Galata and Beyoğlu, with İstiklal Avenue and the Galata Tower. Across the Bosphorus, Kadıköy and Üsküdar are the main Asian districts. From Sultanahmet to Eminönü is a 15-minute walk downhill; from Sultanahmet to Galata Tower is 25 minutes via the Galata Bridge.

Getting around

The single transit card is the Istanbulkart, a contactless chip card you top up with money. It works on the metro, trams, buses, funiculars and ferries, and a ride costs around 15 TL with a full fare. The T1 tram is the workhorse for tourists: it runs from the old city to Kabataş via Eminönü and Karaköy. The M2 metro connects Taksim to the old city via a funicular. Traffic is dense, so on the surface the tram is often faster than a taxi. Walking between Sultanahmet and Eminönü takes 15 minutes; between Karaköy and Taksim, 20.

Where to stay

Sultanahmet
The tourist core, with Hagia Sophia, the Blue Mosque, Topkapı Palace and the Basilica Cistern within walking distance. Everything is geared to visitors, so hotels are pricey and restaurants are average. It is convenient for a short first trip, but the area empties out early in the evening.
Beyoğlu (Taksim)
The modern centre, anchored by Taksim Square and the pedestrian İstiklal Avenue. This is where you find bars, live music, and a younger crowd. It has the liveliest nightlife in the city, but the old town is a 10-minute funicular ride and a 15-minute tram ride away.
Karaköy and Galata
Just across the Galata Bridge from the old city, these Ottoman-era lanes have been turned into a district of design shops, coffee houses and boutique hotels. The Galata Tower is here, and it is a good base for walking both to Istanbul's main sights and to the nightlife of Taksim.
Kadıköy
On the Asian side, a 15-minute ferry ride from Eminönü. It is a residential area with a strong food scene: markets, meyhanes and cafes clustered around the ferry dock. Staying here means a slower pace and better restaurants, but you will ride the ferry for every museum visit.
Balat
A former Jewish quarter with steep streets, colourful houses and lots of cats. It has been gentrified into a cafe district, but it is still quiet and local. The metro does not reach it, so you rely on buses or a long walk from the main sights. Good for a half-day visit, but not as a base.

A day here

A day in the old city and a ferry ride

  1. Hagia SophiaArrive before 09:00. It is now a working mosque, so entry is free, but you will queue and must cover your head and shoulders. The 6th-century dome is the point; give it a good look from the upper gallery if it is open. Spend one hour, or two if you want to read every panel.
  2. Basilica CisternA five-minute walk from Hagia Sophia, opposite the tram stop. This underground chamber holds rows of columns and oddly inverted Medusa heads. The effect is cool and dark, a relief on a hot day. It takes 30 minutes, and the entry ticket can be bought on a phone. Go early, because lines form after 10:00.
  3. Topkapı PalaceThe sultans' residence for four centuries. The courtyards are vast, the views over the Bosphorus are wide, and the Harem is worth the extra ticket. Set aside three hours and buy your ticket at the machine outside. The palace is closed on Tuesdays, so check the day before.
  4. Fish sandwich at EminönüWalk downhill from Topkapı to the Galata Bridge, about 20 minutes. Along the quay, moored boats sell grilled fish sandwiches (balık ekmek) for around 150 lira. Eat one standing on the waterfront. The sandwich is the point; the surrounding noise is part of the experience.
  5. Ferry to KadıköyFrom Eminönü pier, take a ferry across the Bosphorus to Kadıköy, a 20-minute ride. The boat offers the best view of the city's skyline. In Kadıköy, walk through the market street and have Turkish coffee or tea before returning. The return ferry runs every half hour.

Eating

Balık ekmek (fish sandwich)
Grilled fish on a bun with onions and greens, sold from boats at Eminönü and also near the fishermen under the Galata Bridge. The boats are a working version of a food stall: you pay, you get a sandwich, you eat standing. It is not fine dining, but the fish is fresh and the setting is the point.
Simit
The universal street bread: a sesame-covered ring sold from carts and stands everywhere. It tastes best straight from the oven, and is often eaten with cheese and tea for a fast breakfast. Cheap enough that you will buy one every day.
Döner and kebap
Istanbul has thousands of kebab shops, from sandwich-style döner to sit-down pide and lahmacun places. For a proper meal, order a mixed kebab or a pide sausage with a side salad. You will rarely go wrong in a full shop where locals queue at lunchtime.
Lokanta
A simple, everyday Turkish restaurant where the day's cooking is displayed in bain-marie. You point at the dishes you want: stews, vegetables in olive oil, beans, rice. These are the most honest and cheapest meals in the city, and they are mostly found in working-class neighbourhoods.
Turkish breakfast
A spread of olives, cheese, tomatoes, eggs, jams, honey, bread and tea, enough to last two hours. It is served in cafes all over, but the tradition is strongest in the Asian side and in places like Beşiktaş. Order it when you have a long morning and nowhere to be.
Meze and rakı
A meyhane is a tavern serving small plates (meze) and the aniseed drink rakı. The custom is to share several dishes and sip slowly over the evening. In Beyoğlu and Kadıköy there are many meyhanes; they get busy after 21:00 and you may need a reservation.
Tatlı (baklava and Turkish delight)
Sweet shops cluster around the Spice Bazaar, with trays of pistachio baklava and boxes of lokum (Turkish delight). The quality varies widely; the best shops use pistachio paste rather than cream. Buy in small quantities and taste before you commit.

Practical

Money
The lira is the currency. Cards work in hotels, restaurants and museums, but street stalls and small shops expect cash. ATMs are common. Entry fees to major sights change with inflation; check the official museum websites for current prices. A realistic daily spend for food and transport is around 2,000 lira, not including hotels.
Transport
Public transport runs on the contactless Istanbulkart; the card costs a small deposit and can be topped up at machines. One ride costs around 15 to 20 lira. The T1 tram, M2 metro, buses and ferries are all covered. Taxis are metered but often quote a flat fare; take an official taxi with a yellow roof, and agree on the price in advance.
Safety
The city is generally safe for tourists. Pickpocketing occurs in the tram, in the Grand Bazaar, and around Taksim, so keep your wallet in a front pocket. At night, stick to well-lit streets; the areas of Tarlabaşı and Aksaray have a rougher edge. There is a visible police presence, especially in the old town.
Opening hours
Museums keep different hours. Topkapı Palace is closed on Tuesdays; the Basilica Cistern opens daily until 19:00; Hagia Sophia is a mosque, so it closes for prayer times. Shops in the old city open around 09:00-20:00, but many close for lunch. Restaurants run from roughly 11:30 until 23:00.
Seasons
Spring and autumn are the most comfortable seasons, with temperatures between 15 and 25 degrees. Summer is hot and crowded, winter is cold and rainy. If you can, come in April or September.

Worth knowing

  • Topkapı Palace closes on Tuesdays, and Hagia Sophia closes for daily prayers.
  • There is no Uber; use the metro or a taxi. Taxis occasionally refuse the meter, so insist or take another.
  • Ferries are a normal way to travel, not a tourist cruise. A regular ferry between Eminönü and Kadıköy costs the same as a tram ride.
  • Mosque rules apply: women cover their hair, everyone covers shoulders and knees.
  • You will be offered shoeshines, carpets, and 'guides' near the Blue Mosque. Politely say no and keep walking.
  • Rakı, the aniseed spirit, is a drink to sip slowly with food. Do not drink it like a shot.

Questions

How many days do you need in Istanbul?
Four days covers the historic centre, a ferry ride, and one Asian-side neighbourhood. With five or six you can add more neighbourhoods and a day trip up the Bosphorus. Anything less than three feels rushed.
Is Istanbul expensive to visit?
It is cheaper than most European capitals, but not as cheap as it was ten years ago. A street meal costs around 150 lira, a museum ticket is 300 to 1,200 lira depending on the site, and a budget hotel starts at about 1,500 lira a night. Set aside 2,000 to 3,000 lira a day per person for a comfortable trip.
Can you walk everywhere in Istanbul?
The historic area from Hagia Sophia to the Grand Bazaar is walkable, and walking is often faster than driving in traffic. But the city is a huge metropolis; you will use the tram, metro or ferry to get between the main districts. Walking 15,000 steps a day is normal here.
Do people in Istanbul speak English?
In the tourist districts you will be fine with English, especially in hotels, museums and restaurants. Outside those areas, Turkish is the only option, but people are patient and Google Translate works well. Learning a few phrases like 'merhaba' and 'teşekkür ederim' helps a lot.
Is Istanbul safe at night?
Central areas like Sultanahmet, Karaköy and Taksim are busy and safe into the early morning. Use the same caution you would in any large city: avoid dark alleys, don't flash money, and take a registered taxi if you are alone. The main risk is petty theft, not violent crime.
Is Istanbul worth visiting in winter?
Yes, if you don't mind cold weather and rain. The museums are open, the queues are short, and the city has a quieter, more local feel. Hotel prices drop by half compared with summer. Pack warm clothes, a waterproof jacket, and you will have a good time.
Are the big sights overrated?
Hagia Sophia is not overrated. It has been a church, a mosque, a museum and a mosque again, and its dome is spectacular. Topkapı Palace is also significant, but it is crowded and expensive. The Blue Mosque is a fine example of Ottoman design, but it is closed to non-worshippers during prayers. The Grand Bazaar is a labyrinth of stalls and mostly a tourist trap; treat it as a bazaar, not a market for bargains.
