Overview
Istanbul is one of the few cities in the world that spans two continents — its European side separated from its Asian side by the Bosphorus strait, a working waterway that has shaped commerce and culture for millennia. With a metropolitan population exceeding 15 million, it is Turkey's largest city and its economic and cultural heart, though Ankara is the national capital.
The city's layered history is extraordinary. Known as Byzantium under Greek settlement, then Constantinople as the capital of the Eastern Roman (Byzantine) Empire, and finally Istanbul after the Ottoman conquest of 1453, it has been one of the world's great cities for roughly 2,700 years. The UNESCO-listed Historic Areas of Istanbul contain some of the planet's most visited monuments within a walkable radius.
Modern Istanbul is far more than its monuments. Neighbourhoods such as Beyoğlu, Karaköy, Kadıköy and Beşiktaş pulse with contemporary art galleries, independent restaurants, live music venues and a young, outward-looking population. Visitors who venture beyond the obvious tourist corridors of Sultanahmet tend to leave with a richer and more honest picture of the city.
Before You Go
Visas
Entry requirements for Turkey vary significantly by nationality — including e-visa eligibility, visa-on-arrival availability and exemptions. Do not rely on secondhand information. Check TravelerPulse's Visas section for general guidance, then confirm current requirements with Turkey's official e-Visa portal (evisa.gov.tr) or your nearest Turkish consulate well before travel.
Passport Validity
Most authorities advise that your passport be valid for at least six months beyond your intended stay. Verify the current requirement for your nationality before booking.
Health
No mandatory vaccinations are required for most nationalities entering Turkey as a tourist, but consult your doctor or a travel health clinic for recommended immunisations. Tap water in Istanbul is technically treated but many locals and visitors prefer bottled or filtered water. Travel health and medical evacuation insurance is strongly recommended.
Currency and Cards
The Turkish Lira (TRY) is the only legal tender. Major credit and debit cards are widely accepted in hotels, larger restaurants and shops, but smaller eateries, market stalls and minibuses often operate cash-only. ATMs (known locally as 'bankamatik') are plentiful throughout the city. Exchange rates and fees vary — compare options before exchanging large sums.
Connectivity
International roaming can be expensive and SIM card regulations for foreign visitors have changed in recent years — verify the current process for purchasing a local SIM with your provider or at the airport on arrival. Portable Wi-Fi hire is available at Istanbul Airport.
Getting There
By Air
Istanbul is served by two major airports. Istanbul Airport (IST) on the European side is the primary international hub and one of the busiest airports in Europe, with direct flights from most major world cities. Sabiha Gökçen International Airport (SAW) on the Asian side handles substantial low-cost carrier traffic, particularly within Europe and the Middle East. Confirm which airport your flight uses when booking, as they are roughly 70–90 km apart by road.
Transfer times from Istanbul Airport to the city centre vary considerably depending on traffic — the metro connection (M11 line) offers a more predictable journey than road transfers at peak hours. Sabiha Gökçen is connected to the Asian side of the city by bus services and to the European side via bus or ferry combinations. Verify current schedules and fares locally or through official operator websites.
By Sea
Several cruise lines include Istanbul as a port of call, docking at Galataport in Karaköy — a short walk or taxi ride from central Beyoğlu and a ferry ride from Sultanahmet.
By Rail
Istanbul is connected to the European rail network via the Balkans, with the Halkalı station on the European side serving international and domestic long-distance services. High-speed rail links Istanbul with Ankara and several other Turkish cities from Pendik station on the Asian side. Check current timetables with TCDD (Turkish State Railways) directly.
Getting Around
Public Transport
Istanbul has an extensive public transport network including metro lines, trams, funiculars, buses, minibuses (dolmuş) and ferries. The Istanbulkart is a rechargeable contactless card that works across virtually all public transport modes and offers discounted fares compared to single-ride tokens. It can be purchased and topped up at machines in stations and at kiosks throughout the city. Regulations around tourist use of Istanbulkart have changed periodically — confirm current rules on arrival.
The T1 tram line is particularly useful for tourists, running through Sultanahmet, across the Galata Bridge and up to Kabataş. The M2 metro line connects the airport area to Taksim Square on the European side. The Marmaray rail tunnel links the European and Asian sides beneath the Bosphorus.
Ferries
Ferry travel across the Bosphorus and the Golden Horn is one of Istanbul's genuine pleasures and also a practical way to move between districts. IDO and Şehir Hatları operate scheduled services; fares are payable by Istanbulkart on most routes. Schedules vary by season — check current timetables.
Taxis and Ride-Hailing
Yellow taxis are ubiquitous. Insist that the meter is running at the start of every journey. Ride-hailing apps including BiTaksi and the local integration with other platforms are available and can provide greater fare transparency. Agree on fares in advance for airport transfers where metered cabs are not used.
On Foot
Sultanahmet, Beyoğlu and Karaköy are walkable, though Istanbul's hills can make some routes tiring. Comfortable footwear is essential.
Things to See & Do
Historic Sultanahmet
The Hagia Sophia Grand Mosque (Ayasofya) is the city's defining monument — a 6th-century Byzantine basilica converted to a mosque under the Ottomans and again in 2020. Entry is free for worshippers during prayer times; at other times, admission is charged for non-worshipping visitors — verify current fees and hours on site or via official sources before visiting. Dress modestly; women are required to cover their hair inside.
The Blue Mosque (Sultan Ahmed Mosque) directly opposite is still an active place of worship. Entry for non-Muslim visitors is permitted outside prayer times; no admission charge, though donations are customary. The Topkapı Palace served as the administrative centre of the Ottoman Empire for centuries and now houses extraordinary collections of imperial artefacts, porcelain, weapons and the Harem. The adjacent Istanbul Archaeology Museums are among the finest in the region.
The Bazaars
The Grand Bazaar (Kapalıçarşı) is one of the world's oldest and largest covered markets, with thousands of shops across a labyrinthine network of streets. It is extremely busy; be prepared for persistent sales approaches. Nearby, the Spice Bazaar (Mısır Çarşısı) in Eminönü is more manageable and excellent for purchasing teas, spices, Turkish delight and dried fruit. Verify opening days, as both bazaars observe weekly closures.
The Bosphorus
A public ferry ride up the Bosphorus toward the Black Sea offers views of Ottoman-era yalıs (waterfront mansions), fortresses and two suspension bridges. This is one of the best-value experiences in the city. Private Bosphorus tours are also widely available — compare operators carefully.
Beyond Sultanahmet
- Galata Tower — medieval Genoese tower with panoramic city views; expect queues
- Dolmabahçe Palace — 19th-century Ottoman palace on the Bosphorus European shore; guided tours only, verify hours
- Chora Church (Kariye Mosque) — extraordinary Byzantine mosaics; check current access status as restoration and conversion work has affected visitor access in recent years
- Kadıköy (Asian side) — vibrant market neighbourhood, excellent street food and a lively local atmosphere
- Princes' Islands (Adalar) — car-free islands in the Sea of Marmara reachable by ferry; popular day-trip destination
- Pera Museum — well-curated art museum in Beyoğlu with notable Ottoman-era paintings and special exhibitions
Food & Drink
What to Eat
Istanbul's food scene ranges from street-side snacks to refined Anatolian cuisine. Key dishes and foods to seek out include:
- Simit — sesame-encrusted bread rings sold by street vendors throughout the city
- Balık ekmek — grilled fish sandwiches sold from boats near the Galata Bridge in Eminönü; a genuine Istanbul institution
- Döner — pressed and spit-roasted meat, served in bread or on a plate; quality varies greatly by establishment
- Kokoreç — seasoned offal grilled on a spit and served in bread; very popular locally
- Meze — a spread of cold and warm small dishes, central to any serious Turkish meal
- Lahmacun — thin, crisp flatbread topped with spiced minced meat; best eaten fresh and hot
- Turkish breakfast (kahvaltı) — an elaborate spread of cheeses, olives, eggs, tomatoes, cucumbers, honey and preserves; weekend neighbourhood spots in Kadıköy and Beşiktaş do this particularly well
Where to Eat
Sultanahmet has many restaurants oriented toward tourists; quality and value can be inconsistent. Neighbourhoods such as Kadıköy, Karaköy, Cihangir and Moda generally offer better food at fairer prices. The streets around the Spice Bazaar and Eminönü waterfront are reliable for casual, inexpensive eating.
Drinks
Turkish tea (çay) is the national drink, served in small tulip-shaped glasses and offered constantly throughout the day. Turkish coffee is thick, unfiltered and served in small cups — do not drink the grounds. Ayran (a cold, salted yoghurt drink) is the default pairing with grilled meat dishes. Alcohol is available in many restaurants, bars and shops — Istanbul has a lively bar scene particularly in Beyoğlu, Karaköy and Kadıköy — though it is not available everywhere, and prices are higher than in many European cities due to taxation. Rakı, an anise-flavoured spirit traditionally diluted with water, is Turkey's national spirit and typically consumed with meze and fish.
Shopping
Istanbul offers shopping experiences ranging from ancient bazaars to contemporary boutiques. The Grand Bazaar and Spice Bazaar are the most famous retail destinations, though visitors should approach prices as a starting point for negotiation rather than fixed. Having a clear sense of fair market value before bargaining is helpful.
For more curated and fixed-price shopping, the Nişantaşı neighbourhood on the European side is Istanbul's upmarket retail district, with Turkish and international fashion labels. Karaköy and Beyoğlu have a concentration of independent design stores, bookshops and concept stores.
Popular items to bring home include hand-painted ceramics and tiles (look for Kütahya or Iznik-style work), hand-woven textiles and kilims, Turkish tea sets, quality spices, Turkish delight (lokum) from reputable producers and leather goods. Be cautious with carpets — it is a high-value purchase requiring research; avoid high-pressure sales and always obtain a receipt with full provenance details. Export of genuine antiques requires official permission; reputable sellers will advise on this.
Practical Information
Emergency Numbers
Turkey's emergency numbers are standardised: 112 for general emergency and ambulance, 155 for police, 110 for fire. Verify these are current on arrival.
Electricity
Turkey uses Type F (Schuko) plugs at 230V/50Hz. Travellers from North America, the UK and some other regions will need an adaptor and possibly a voltage converter for older devices.
Tipping
Tipping is customary but not obligatory. In restaurants, rounding up the bill or leaving 10–15% is common at sit-down establishments; check whether a service charge has already been added. Taxi drivers, hotel porters and tour guides generally appreciate tips; amounts are at your discretion.
Photography
Shooting in public spaces is generally permitted, but always ask permission before photographing individuals. Photography inside mosques during prayer is inappropriate and in some cases restricted. Some museums prohibit flash or tripods — look for posted signs.
Time and Dates
Turkey no longer observes daylight saving time. The entire country operates year-round on UTC+3. This means Istanbul's time relationship with European cities shifts by one hour depending on the season.
Safety
Istanbul is a major international city and visitors should apply the same common-sense precautions they would anywhere of this scale. Petty theft — pickpocketing in crowded bazaars, tourist sites and public transport — is the most common issue affecting visitors. Keep valuables secured and be particularly vigilant in the Grand Bazaar, on the T1 tram and in Taksim Square.
Scams targeting tourists are well-documented in Istanbul. Common ones include the 'shoe shine' approach (a stranger drops a brush, then offers an unsolicited shine for an inflated fee), being steered toward overpriced restaurants or carpet shops by seemingly friendly strangers, and taxi drivers taking longer routes or claiming card machines are broken. Being aware of these in advance is the best defence.
Check your government's current travel advisories before departure — the security situation, as in any large city, can change. Most governments maintain advisories for Turkey that note standard big-city precautions without advising against tourist travel to Istanbul's main areas; verify the current status through your own government's official travel advice site.
Female travellers generally navigate Istanbul without major difficulty, particularly in central and tourist-oriented areas. As in any city, situational awareness and confidence are the most useful tools. LGBTQ+ travellers should be aware that while Istanbul has historically had a visible LGBTQ+ community, the social and legal environment in Turkey has become more restrictive in recent years — research current conditions and exercise discretion.
Local Culture & Etiquette
Istanbul is a secular city within a constitutionally secular state, but Islam is practised by the majority of its population and Islamic culture is woven into daily life. The call to prayer (ezan) sounds from minarets five times daily across the city — it is part of the city's ambient fabric and not unusual to hear at any hour. During Ramadan, eating and drinking in public during daylight hours is not illegal for non-Muslims but is considered disrespectful in more conservative areas; be observant of your surroundings.
When entering any mosque, both men and women should dress modestly — shoulders and knees covered. Women are required to cover their hair; scarves are often available to borrow at mosque entrances. Remove shoes before entering.
Greetings are important in Turkish culture. A polite Merhaba (hello) and Teşekkür ederim (thank you) are always appreciated. Turks are generally warm and hospitable to visitors, and making even a small effort with the language is well received.
Be aware that certain topics — including the Kurdish question, the Armenian Genocide and criticism of founding figures of the Republic — are politically and socially sensitive. Travellers are advised to listen more than they speak on such subjects, particularly with people they have just met.
