Straddling two continents on the Bosphorus, Istanbul rewards a tightly planned 48 hours. Here’s a walkable, verified itinerary through its historic peninsula, Galata and Beyoğlu.
Istanbul is the only major city on earth split across two continents, its European and Asian shores divided by the Bosphorus, a 31-kilometre strait linking the Black Sea to the Sea of Marmara. Roughly two-thirds of its more than 15 million residents live on the European side, and while I love both sides, for a first, tightly timed visit, it’s the European side where I’d suggest you should base yourself.
The historic peninsula, Galata and Beyoğlu hold the overwhelming majority of the sights worth your 48 hours, all reachable on foot or via a single tram or ferry hop.
A second waterway, the Golden Horn, cuts into the European side itself, separating the old walled city of Sultanahmet and Fatih from the 19th-century quarters of Galata and Beyoğlu to its north. Understanding that single geographical fact, old city south of the Golden Horn, newer European quarter north of it, Bosphorus running east, is really all the orientation you need before you land.
Arrival and Getting Into the City
Istanbul is served by two airports, and which one you land at matters. Istanbul Airport (IST), on the European side, is the larger, newer hub used by most international carriers, sitting around 50 kilometres northwest of the centre. From Istanbul Airport, journey time into Sultanahmet or Taksim runs 45 to 90 minutes depending on traffic.
In addition, the M11 metro line runs from inside the airport to Gayrettepe, where you change onto the M2 line for Taksim, and operates from 6 am to midnight, offering the cheapest and most predictable option. Meanwhile, HAVAIST airport buses run to Taksim and other hubs for a similar price, and metered taxis into town typically costs US$35-55.
From Sabiha Gökçen Airport (SAW), which sits on the Asian side and is used mainly by budget and regional carriers, the M4 metro line runs directly from the terminal to Kadıköy in around 50 minutes.
Whichever airport you land at, buy an Istanbulkart on arrival, a rechargeable smart card that works across every metro line, tram, bus and ferry in the city, sold from kiosks in both arrival halls.
Safety and Getting Around
Istanbul is, in the main, a safe and welcoming city for visitors, and the well-trodden tourist districts of Sultanahmet, Fatih, Beyoğlu and Beşiktaş see heavy foot traffic at all hours. However, standard city precautions apply so keep an eye on your pockets and your bags in crowded bazaars, use only licensed, metered taxis or a ride-hailing app and take normal care walking alone late at night.
Getting around is straightforward once you have that Istanbulkart. The T1 tram is the single most useful line for a 48-hour visit, running from the old city through Sultanahmet, past Eminönü and across the Galata Bridge to Karaköy and on to Kabataş.
The nostalgic T2 tram trundles the length of İstiklal Avenue between Tünel and Taksim. I love doing both for the people watching and local inspiration.
Ferries, run largely by the municipal operator Şehir Hatları, are cheap, frequent and arguably the best way to see the city’s skyline. For door-to-door trips, both Uber and the locally dominant BiTaksi app operate reliably in Istanbul are are preferable to hailing a cab on the street, since it removes any ambiguity over the fare.
Day One: The Historic Peninsula
Spend your first day entirely within the old walled city of Sultanahmet and neighbouring Eminönü, an area compact enough to cover on foot without ever needing transport.
Start at Hagia Sophia, open to visitors daily from 9 am (closed to non-worshippers around Friday midday prayers), arriving as close to opening as you can manage to beat the tour groups. As an active mosque since 2020, modest dress is required, so pack clothing that covers shoulders and knees, and, for women, a headscarf (though scarves are available free at the entrance).
From there it’s a two-minute walk across Sultanahmet Square, past the Hippodrome’s obelisks, to the Blue Mosque (Sultan Ahmed Mosque), which is free to enter outside prayer times and is closed to visitors until early afternoon on Fridays.
Next, head to the Basilica Cistern, the 6th-century underground reservoir that reopened in 2022 after a five-year restoration that added new lighting, art installations and a reworked walkway through its forest of columns. A word of warning, it’s as humid as a steam room down there and expect crowds, especially during the busy summer months.
From there, it’s a ten-minute walk uphill to Topkapı Palace, the Ottoman sultans’ seat of power for nearly 400 years. You’ll want to budget at least three hours for the palace (which is closed on Tuesdays), and decide in advance whether to add the separately ticketed Imperial Harem.
Break for lunch at Pandeli, the celebrated Ottoman-Greek restaurant that’s operated above the entrance to the Spice Bazaar since 1901, its Iznik-tiled dining rooms having hosted guests from Atatürk to Audrey Hepburn.
In the afternoon, delve into the Spice Bazaar (one of my favourite Istanbul attractions) before walking up to the Grand Bazaar (note that it’s closed on Sundays), one of the world’s oldest and largest covered markets. Even if you’re not in the mood to shop, I’d still recommend exploring this fascinating labyrinth just for the vibe, which is unlike anywhere else. Cool down at one of the fresh orange juice stands and drink in the accents, faces and culture that flood its narrow lanes.
From there it’s a short walk to the Süleymaniye Mosque, Mimar Sinan’s 16th-century masterpiece commissioned by Süleyman the Magnificent, which crowns the old city’s highest hill with sweeping views over the Golden Horn. Loop back down through the Spice Bazaar (grab some freshly roasted coffee at Kurukahveci Mehmet Efendi, which has traded in the Bazaar since 1871) before the day ends.
After lingering on the Eminönü waterfront, and stopping for a fortifying thimble of turşu suyu, the sour-sweet pickle juice sold at stalls along the promende, make for Hamdi Restaurant, which has grown from a single kebab counter in the 1960s into an Istanbul institution. Grab a table on the rooftop terrace looking out over the Golden Horn, the New Mosque and the Bosphorus Bridge beyond.
Day Two: The Bosphorus, Galata, Karaköy and Beyoğlu
Begin early at the Eminönü ferry piers with Şehir Hatları’s short Bosphorus tour, a two-hour round trip that threads between the continents past Ottoman palaces, fortresses and waterfront mansions, returning you to Eminönü by mid-morning. This is not only a great way to get your bearings but to spy the regal residences (including some of the city’s most beautiful luxury hotels) perched above the water.
From there, walk across the Galata Bridge, its lower deck lined with fish restaurants and its upper deck with local anglers, into grungy-cool Karaköy, making your way up the narrow, cobblestone lanes to Galata Tower, a 14th-century Genoese watchtower standing 67 metres tall. Open daily from 8.30 am, the tower houses a museum and from the top you’ll enjoy panoramic views over the old city and the Bosphorus.
Wander Karaköy‘s steep backstreets, now filled with independent design shops and galleries, before lunch at Karaköy Lokantası, a modern take on the traditional Turkish lokanta serving classics like hünkar beğendi in a room of turquoise İznik-inspired tiles.
In the afternoon, climb (or, if the legs are feeling those hills, take the historic Tünel funicular) up into Beyoğlu and join İstiklal Avenue, the pedestrianised heart of 19th-century Pera, where the nostalgic T2 tram still trundles past late Ottoman facades. Duck into the Çiçek Pasajı, an 1876 flower market turned meyhane-lined arcade, and the Pera Museum, housed in the former Bristol Hotel, before the avenue delivers you to historic Taksim Square.
Close your 48 hours the way many Istanbullus would choose to, at Mikla (above), chef Mehmet Gürs’s New Anatolian restaurant on the top two floors of the Marmara Pera Hotel just off İstiklal. Michelin-starred since 2023, its 18th-floor terrace offers a 360-degree view across both continents as the city’s lights come up.
Istanbul Travel FAQ
The most commonly asked practical questions about visiting Istanbul, covering visas, money, dress code and how much time you really need.
Do I need a visa to visit Istanbul?
It depends on your passport. Major Asian countries enjoy visa-free access, typically for up to 90 days, including South Korea, Singapore, Japan, China, Indonesia, and Malaysia. Citizens of the US, Canada, Australia and several other countries need an e-Visa, obtained in advance at the official government portal.
What currency should I use, and is Istanbul a cash or card city?
The currency is the Turkish lira (TRY). Cards are widely accepted in hotels, restaurants and larger shops, but small vendors, market stalls and some historic sites still prefer cash, so carry a reasonable amount of lira for day-to-day spending. Tipping in restaurants runs 10–15% where a service charge isn’t already included; round up for taxis.
Is it safe to drink the tap water?
Istanbul’s tap water is treated and technically safe, but the taste is poor and older pipework varies by building, so most residents and visitors alike drink bottled or filtered water, which is inexpensive and sold everywhere.
What should I wear, especially for mosques?
Istanbul is a modern, largely secular city, and everyday dress codes are relaxed. Inside working mosques such as Hagia Sophia and the Blue Mosque, however, shoulders and knees must be covered, and women need a headscarf; both are provided free at the entrance if you arrive without one. Shoes come off before entering the prayer hall.
How many days do you really need in Istanbul?
Two focused days, as above, will comfortably cover the historic peninsula, Galata, Karaköy and Beyoğlu. A third or fourth day is well spent on the Bosphorus villages of Ortaköy and Bebek, the Asian-side neighbourhood of Kadıköy, or Dolmabahçe Palace, none of which are essential to a first, efficient visit but all reward those with more time.
What’s the best time of year to visit?
Spring (April to May) and autumn (September to October) bring mild, dry weather and thinner crowds than the height of summer, making them the best all-round windows for a 48-hour visit focused on walking.
