The guide

Istanbul stretches across two continents, on either side of the Bosphorus. On the European side, Sultanahmet, the old city, gathers the historic treasures: Hagia Sophia, the Blue Mosque, the Basilica Cistern and Topkapı Palace, all within walking distance. Across the Golden Horn, Beyoğlu climbs toward the Galata Tower and the pedestrian İstiklal Avenue, a realm of cafes, bars and nightlife. To feel the local pulse, cross to the Asian side to Kadıköy, a hip, laid-back district known for its market, independent cafes and street art. In between, a Bosphorus cruise or even a simple ferry crossing offers the finest views over the palaces, mosques and hills of the city.

«Skyfall» (2012) opens with a chase over the Grand Bazaar; «From Russia with Love» (1963) already filmed Hagia Sophia and the Basilica Cistern. Istanbul was born for the screen.

Istanbul is the only city straddling two continents: you can have lunch in Europe and dinner in Asia by crossing the Bosphorus.

Quiet spot: the colorful lanes of Balat, then a public ferry across the Bosphorus at sunset. With a data eSIM, transit apps replace haggling and you sidestep taxis that pad the fare.

Must-see

Hagia Sophia
A former Byzantine basilica turned mosque, the thousand-year-old jewel of Sultanahmet, famous for its vast dome and mosaics. A three-minute walk from the Sultanahmet tram stop (T1 line), facing the Blue Mosque.
Grand Bazaar
One of the world's largest covered markets, a maze of thousands of stalls: carpets, copperware, jewelry, spices. Get off at the Beyazıt-Kapalıçarşı tram stop, right in front of one of the main entrances.
Galata Tower
A medieval tower dominating Beyoğlu, whose top offers a 360-degree panorama over the old city, the Golden Horn and the Bosphorus. Reached from the Karaköy stop followed by a steep ten-minute walk uphill.
Bosphorus
The strait separating Europe from Asia. A two- to three-hour cruise, or a simple public ferry, glides past palaces, fortresses and waterside villages; one of the finest moments of any visit to Istanbul.

Good to know

Spring (April-May) and autumn (September-October) are the ideal seasons, with mild temperatures and fewer crowds than at the height of summer. The city is easy to navigate by transit: the T1 tram links Sultanahmet, the Grand Bazaar and Galata, complemented by the metro and especially the ferries, which double as scenic rides between the two shores. Get an Istanbulkart, a rechargeable card valid on trams, metros, buses and ferries, and far cheaper. On connectivity, a free municipal wifi covers many squares, parks and transport lines, and most cafes and hotels are connected; mobile coverage in the city is generally good.
