Give Istanbul four days and split them by geography rather than by theme. One for the historic peninsula, where Hagia Sophia, the Blue Mosque, Topkapı and the Basilica Cistern sit within ten minutes of each other. One for Galata, Karaköy and Beyoğlu on the far side of the Golden Horn. One for the Bosphorus, which means a ferry north in the morning and a palace or a waterfront district in the afternoon. And one on the Asian side, which is where the city stops performing for visitors.
Istanbul is two cities that share a name and a strait. The historic peninsula is dense, monumental and busy from nine in the morning; Kadıköy across the water is residential, loud in the evening and almost entirely Turkish. The Bosphorus between them is not a barrier but the transport network, and a ferry ticket costs the same as a tram ride. The useful instinct is to stop treating a continental crossing as an excursion. Cross twice a day and the city starts to make sense.
Landmark· Sultan Ahmet, Ayasofya Meydanı No:1, 34122 Fatih, Istanbul
Completed in 537 as the cathedral of Constantinople, converted to a mosque after the Ottoman conquest of 1453, run as a museum from 1935, and a working mosque again since 2020. The dome is what people come for: it spans roughly 31 metres and rides on pendentives that make the whole weight look optional. Foreign visitors enter through the upper gallery, which is also where the surviving Byzantine mosaics are. Shoulders and knees covered, heads covered for women, and no visits during the prayer itself.
The seat of the Ottoman court for close to four centuries, laid out as four courtyards that get quieter and more restricted the further in you walk. Check that your ticket covers the Harem, the section most people regret skipping; the Imperial Treasury and the Sacred Relics rooms are the other two that justify the queue. The fourth courtyard terrace looks down over the Golden Horn and the Bosphorus at once. Half a day, and check the closing day before you build a morning around it.
Mosque· Binbirdirek, At Meydanı Cd No:10, 34122 Fatih, Istanbul
Built between 1609 and 1616 for Ahmed I, and still the working neighbourhood mosque it was designed to be. The name comes from the İznik tilework lining the upper walls, best read in late-morning light when the windows are doing the work. Six minarets, which was controversial at the time. Visitors use the north entrance, the dress code is the same as Hagia Sophia, and the doors close to non-worshippers around each of the five prayers.
Market· Beyazıt, Kalpakçılar Cd. No:22, 34126 Fatih, Istanbul
Trading since the 1450s across roughly sixty covered streets, which makes it one of the oldest covered markets anywhere still doing its original job. The tourist trade sits on the main axis; the interesting parts are the hans off the sides, where the gold, the carpets and the antique dealers actually work. Prices are negotiable and everyone expects it. Enter at Nuruosmaniye and let yourself get lost, because there is no efficient route through it.
Boat trip· Eminönü ferry terminal, Rüstem Paşa, 34116 Fatih, Istanbul
The public ferry north from Eminönü is the best-value sightseeing in the city and costs a fraction of the private cruises tied up beside it. You pass the two palaces, the wooden yalı houses, both bridges and the Rumeli Hisarı fortress before the strait opens towards the Black Sea. Sit on the top deck, port side heading north. Anadolu Kavağı at the far end is a fishing village with a ruined castle above it and a couple of hours before the boat turns around.
Landmark· Alemdar, Yerebatan Cd. 1/3, 34110 Fatih, Istanbul
A sixth-century underground reservoir built under Justinian to hold water for the Great Palace, and the strangest fifteen minutes on the peninsula. Three hundred and thirty-six columns stand in shallow water under a lit vault, two of them footed on Medusa heads reused from an older Roman building and set on their side and upside down. It is cool, dim and loud with dripping, which is the point. Recent restoration added contemporary sculpture that not everyone loves.
Mosque· Süleymaniye, Prof. Sıddık Sami Onar Cd. No:1, 34116 Fatih, Istanbul
Mimar Sinan built this for Süleyman the Magnificent between 1550 and 1557, and most people who see both prefer it to the Blue Mosque. The interior is restrained where Sultanahmet is decorated, and the acoustics were engineered rather than inherited. The terrace behind it holds the tombs of Süleyman and Hürrem Sultan and the best free view over the Golden Horn in the city. The old kitchens and the surrounding streets are still part of the complex.
Mosque· Dervişali, Kariye Cami Sk. No:8, 34087 Fatih, Istanbul
The finest late-Byzantine mosaics and frescoes that survive anywhere, in a building small enough to read in an hour. The outer narthex tells the life of Christ, the inner the life of the Virgin, and the side chapel carries a Resurrection fresco that is the single best thing in the room. It reopened in May 2024 after a four-year restoration and now runs a visitor-management system with its own entry fee. Out in Edirnekapı, so pair it with Asitane next door.
Viewpoint· Bereketzade, Galata Kulesi, 34421 Beyoğlu, Istanbul
A Genoese watchtower of 1348, rebuilt more than once, and the reference point for the whole north bank. The balcony gives you the historic peninsula, the Golden Horn and the mouth of the Bosphorus in one turn, which is why the queue forms early and stays. Go in the last hour of daylight if you can stand the wait, or skip the climb entirely and take the view from a Karaköy rooftop instead. The streets below it are the best part of the neighbourhood anyway.
Palace· Vişnezade, Dolmabahçe Cd., 34357 Beşiktaş, Istanbul
When the Ottoman court left Topkapı in 1856 it moved here, into a European palace built on reclaimed shoreline with 285 rooms and 46 halls. The contrast is the reason to see both: Topkapı is a compound of pavilions, Dolmabahçe is one long baroque statement facing the water. The ceremonial hall carries a chandelier heavy enough to need its own structure. Atatürk died in a bedroom here in 1938, and the clocks in that wing are stopped at the hour.
Four is the honest minimum. One day for the historic peninsula, one for Galata and Beyoğlu, one for the Bosphorus and its palaces, and one on the Asian side. A fifth buys you a day trip to the Princes’ Islands without cutting anything else short.
Is Istanbul in Europe or Asia?+
Both. The Bosphorus runs through the middle of the city, with roughly two thirds of the population living on the European side and the rest on the Asian. Crossing is routine: the ferries take about twenty minutes and Marmaray runs under the strait in four.
When is the best time to visit Istanbul?+
April and May, then September and early October. Spring brings the tulips and mild days; autumn holds the warmth without July and August humidity. Winter is cold, occasionally snowy and much quieter inside the monuments.
What should you wear to visit the mosques?+
Shoulders and knees covered for everyone, and a head covering for women. Shoes come off at the door and the big mosques hand out scarves at the entrance. Visits pause around each of the five daily prayers, and Friday midday is the busiest of the week.
What is the easiest way to get around Istanbul?+
Buy an Istanbulkart at any station machine and use it on everything: the T1 tram through the old city, the metro, the funiculars, Marmaray and the ferries. Taxis exist but traffic makes them the slow option across the centre.
Imperial mosques
Best mosques in Istanbul
Six beyond the two on the Top 10, and every one of them still in daily use.
Sinan built it above a row of shops in the market quarter, and the tile work inside is the densest in the city. Easy to walk past: the stairs are unmarked.
Built over the tomb of Abu Ayyub al-Ansari, a companion of the Prophet, and the most visited religious site in Istanbul among Turks rather than tourists. Dress conservatively and keep cameras down.
The one you see from every ferry, finished in 1665 after almost sixty years of stops and starts. Worth the ten minutes for the tiled royal pavilion and the courtyard, which is quieter than the square outside.
A small nineteenth-century mosque on the water with the suspension bridge directly behind it, which is the photograph everyone takes. Come at dusk and eat a kumpir in the square afterwards.
Sinan called this his apprentice work and Süleymaniye his journeyman work, which tells you how high he set the bar. Almost empty most days, ten minutes from the aqueduct.
Sinan pierced the walls with so many windows that the interior reads white rather than stone. Sits on the highest of the seven hills, beside the old land walls and a short walk from Chora.
Fatih Tutak takes regional Anatolian dishes apart and rebuilds them across a long tasting menu. It held two stars in the 2026 Michelin Guide Türkiye. Book well ahead.
Maksut Aşkar cooks recipes collected from across the country inside SALT Galata, with the peninsula filling the windows. Carries both a Michelin star and a Green Star for sourcing.
Mehmet Gürs put Nordic technique behind Turkish ingredients here long before anyone called it a movement. On the top floors of a Pera hotel, so the view is part of the menu.
Musa Dağdeviren has spent decades collecting recipes from the southeast and the menu changes daily according to what he found. Point at what looks good on the steam table. No reservations, no ceremony.
Turquoise tiles, a lunch trade of local office workers and a meze counter that is the reason to arrive hungry. Listed as a Bib Gourmand in the 2026 Michelin Guide Türkiye for value.
The kitchen reconstructs dishes from the Topkapı and Süleymaniye palace kitchen records, some of them five hundred years old. Next door to Chora, which makes the pairing obvious.
Commissioned by Nurbanu Sultan and built by Sinan, and still the easiest historic hamam to walk into without a plan. Separate men’s and women’s sections under the original domes.
Built between 1578 and 1583 for the crews of the Ottoman navy and reopened after a long restoration. A single large dome, one session at a time, and the most careful service of the five.
Thirteen years of restoration brought this one back in May 2024, with the excavated tile fragments displayed in a small museum under the bath. The most considered reopening in the city.
Built under Mahmud I to endow the Hagia Sophia library, and widely described as the last great hamam of the Ottoman era. Grander and busier than the others.
Sinan built it for Hürrem Sultan on the site of the baths of Zeuxippus, directly between Hagia Sophia and the Blue Mosque. The most convenient location and the highest prices.
Built in the 1660s to fund the New Mosque next door, and still mostly spices, dried fruit, lokum and cheese. The lanes outside it, towards the hardware and coffee streets, are better value than the arcade itself.
The second-hand book market between the Grand Bazaar and Beyazıt Mosque, trading on roughly the same spot since Byzantine times. Turkish titles mostly, with a scatter of old prints and maps.
A single lane of shops built to fund the Blue Mosque, and a calmer place to buy a rug or ceramics than the Grand Bazaar. Small enough to walk end to end in ten minutes.
The grid behind the ferry terminal is where the city actually shops: fishmongers, pickle shops, coffee roasters and a Tuesday street market. No souvenir trade at all.
Steep lanes below Galatasaray filled with dealers in furniture, prints and mid-century oddments. The Museum of Innocence sits in the middle of it, which is not a coincidence.
Turkey’s first modern and contemporary art museum, since 2023 in a Renzo Piano building on the cruise terminal. The roof terrace and the reflecting pool are worth the ticket on their own.
The first museum founded in Turkey, holding around a million objects across the main building, the Ancient Orient museum and the Tiled Kiosk. The Alexander Sarcophagus is the headline.
A private museum in a converted hotel, best known for the Orientalist collection and for Osman Hamdi Bey’s The Tortoise Trainer. Compact, well hung, and rarely crowded.
Trains, submarines, cars and machinery in a restored Ottoman foundry and anchor works on the Golden Horn. The one museum in the city that works for children and adults equally.
Orhan Pamuk built a real museum for the objects in his own novel, cabinet by cabinet, and it won European Museum of the Year in 2014. Reads as an installation more than a collection.
The old port quarter, now the densest concentration of good coffee, small restaurants and design shops in the city. Walkable to Galata uphill and one tram stop from the peninsula.
Twenty minutes by ferry and a different city: student bars, record shops, a seafront promenade and the market streets. Where to eat and drink if you want no tourist trade at all.
The old Jewish and Greek quarters on the Golden Horn, steep and coloured and now thoroughly photographed. The Greek Orthodox Patriarchate and the iron church of St Stephen are both here.
A working district with a fish market at its centre, running north along the water past Dolmabahçe to the bridge. Good ferry connections in every direction.
A single street of wooden houses, a synagogue, a church and a mosque within a hundred metres, and a market garden behind. The quietest walk on this list.
The slope below Taksim where writers, cats and long breakfasts have settled. Steep, residential, and looking straight down the Bosphorus from most corners.
Nine islands off the Asian shore, four of them served by ferry and all of them closed to private cars. Büyükada is the largest, with wooden mansions, pine woods and electric shuttles instead of the old horse carriages.
The first Ottoman capital, with the Green Mosque, the Grand Mosque and the silk market inscribed as a World Heritage site. Fastest by fast ferry to Mudanya, then a short bus.
Sinan considered the Selimiye Mosque his masterwork, and it is a World Heritage site in its own right. Around five hours of return driving from Istanbul, which makes this the longest trip here.
Two hours northeast onto the Black Sea, where Istanbul goes in summer: sand, a lighthouse, and two rivers meeting the sea at Ağva. Cooler and rougher than the Marmara side.
A village founded by Polish settlers in 1842 in the forest behind the Asian shore, still keeping the name and the cooking. An hour out, and mostly an excuse to walk and eat a long lunch.
Two weeks of international and Turkish cinema across Beyoğlu and Kadıköy screens, run by İKSV.

IST
Istanbul Airport
The main hub, 40 km northwest on the European side. The M11 metro runs into Gayrettepe for the metro network, and Havaist coaches serve Taksim, Sultanahmet and the Asian side directly.
The second airport, on the Asian side and used by most low-cost carriers. The M4 metro has reached the terminal since 2022 and connects to Kadıköy and, via Marmaray, to the European side.
One contactless Istanbulkart covers the metro, the T1 tram along the historic peninsula, the funiculars and Marmaray, the commuter line that runs under the Bosphorus. Buy the card at any station machine and top it up as you go.
Şehir Hatları has run the crossings since 1851 and the routes are ordinary public transport, priced on the same Istanbulkart as the tram. Eminönü, Karaköy, Kabataş, Beşiktaş, Üsküdar and Kadıköy are the terminals you will actually use.
Grilled mackerel in half a loaf with onion and salad, sold from the boats at Eminönü.

Interesting facts
Istanbul is the only major city in the world built across two continents. The Bosphorus divides it, and the ferries and the Marmaray rail tunnel are the two everyday ways of crossing.
It has been the capital of the Roman, Byzantine and Ottoman empires, under three names: Byzantion, Constantinople and Istanbul.
The province holds 15,754,053 people on the Turkish Statistical Institute’s 2025 count, which is 18.3 percent of Turkey’s population.
Hagia Sophia was the largest cathedral in the world for close to a thousand years after it was completed in 537, and its dome held the record for span in a building of its kind.
Digging the Marmaray tunnel under the Bosphorus uncovered the Theodosian harbour at Yenikapı, and with it dozens of Byzantine shipwrecks, in one of the largest nautical excavations ever run.
