9 Things You Shouldn't Do in Istanbul
Nine things you shouldn't do in Istanbul, from Galata Bridge fish traps to rush-hour taxis, with honest local advice and real 2026 prices.

Istanbul wraps you up the moment you arrive: the smell of the sea, the colours of the bazaars, the call to prayer drifting across the rooftops at sunset. The city has made thousands of travellers fall hard for it. But like any place that draws crowds, it has a few traps. Knowing them in advance is the difference between a great trip and an expensive lesson.

Here is my honest list of things you should not do in Istanbul if you want to see only the city’s best side and bring home good memories instead of a sore wallet. I have lived around this city long enough to have made most of these mistakes myself.
Don’t skip the Asian side of the city
We all learned in school that Istanbul sits on two continents. So why do so many visitors stay glued to the European half? Some run out of time, and a few honestly seem to think the far shore is some kind of backwater. That is nonsense.
The Anatolian side is just as rich in culture and history, and it is where you find the version of Istanbul that locals actually live in. Cross to Kadıköy on a ferry and you land in a neighbourhood of crowded fish markets, record shops, craft breweries and some of the best street food in the city. Walk fifteen minutes south and you reach Moda, where families spread out on the grassy shoreline at sunset with tea from a thermos. It feels calmer, cheaper and more real than Sultanahmet.
My advice: give the Asian side at least half a day. If you can, build in a full one. If you fall for Kadıköy the way most people do, read more about the heart of the Anatolian side.

Don’t trust the first hammam a tout points you to
A traditional Turkish bath is one of the great Istanbul experiences, but the bath you pick matters enormously. Dozens of historic hammams survive across the city, and on paper any of them sounds wonderful. The catch is that some have quietly turned into pure tourist machines, especially around Fatih and the Sultanahmet streets, where touts wave you toward the nearest door.
Don’t follow the first man who calls you over. Do a little homework and choose deliberately. If you want the grand, marble-and-marvel experience, the famous Ottoman houses deliver: Çemberlitaş Hamamı, built by the architect Mimar Sinan in 1584, starts at around 65 euros per person at the time of writing, and the equally historic Çağaloğlu Hamamı sits closer to 90 euros for its base package. They are beautiful, and you pay for it.
If you would rather have the everyday ritual that locals actually use, a neighbourhood hammam often runs 20 to 40 euros for the full wash and scrub. Either way, settle the price before you undress, not after. Our guide to the best hammam addresses in Istanbul lays out the difference in plain terms.
Don’t let restaurant touts reel you in
A good restaurant does not need a man in a waistcoat standing outside grabbing your sleeve. The stretch around the Galata Bridge is thick with these characters, and no matter how romantic “fresh fish with a view of the sea” sounds, keep walking. The places with the loudest pitch are almost never the ones worth your money.
There are spots with a view just as good and food far better, often a few streets back where no one is shouting. If you want fish done properly, browse our pick of the best fish and meze restaurants in Istanbul before you go, and arrive with a name already in mind.
Don’t order fish without checking the price first
This is the single most common way travellers get burned in Istanbul. Near the tourist piers, a plate of fish that should cost a normal amount can land you with a bill that ruins the evening. The classic trick is fish sold “by the gram” at “market price,” then weighed somewhere you cannot see.
So protect yourself. Ask for the exact price before the first bite, every time. If the menu has no printed prices, that is your cue to leave. If it is sold by weight, ask to watch it go on the scale. And if you just want the real Istanbul fish moment without any drama, do what locals do and grab a grilled mackerel sandwich, the famous balık ekmek, from one of the boats bobbing by the Galata Bridge. At the time of writing they run roughly 100 to 150 lira, and they are honestly one of the city’s great cheap pleasures.

Don’t try to see everything in one trip
Grand mosques, sprawling bazaars, mighty fortresses, palaces dripping with gold: you could not exhaust Istanbul’s sights in ten visits, let alone one. So when you land, switch off the part of your brain that wants to tick every box. Chasing the full list turns a holiday into a forced march.
Pick a handful of places that genuinely pull at you, see them well, then stop. Sit down with a cup of Turkish coffee and let the city come to you. That is when Istanbul actually opens up.

Don’t get stuck in traffic at rush hour
Driving across this city is rarely the cheapest or the calmest option, and at rush hour it is neither. Between roughly 8:00 and 9:30 in the morning and again from 5:00 to 7:30 in the evening, the bridges seize up and a taxi ride that should take twenty minutes can stretch past an hour, occasionally close to two.
The smart move is the ferry. A crossing from Eminönü or Karaköy to Kadıköy costs under 60 lira with an Istanbulkart at the time of writing, takes about twenty minutes, and comes with a skyline view no taxi will ever match. Pair it with a short cab ride at the other end and you skip the worst of the gridlock entirely. Sort out your card and routes with our Istanbul ferry timetables and fares, and if you do need a cab, read the Istanbul taxi guide first so you know what a fair fare looks like.
Don’t blindly trust strangers with “helpful” offers
Turkish people are warm and genuinely hospitable, and most strangers who chat with you mean nothing but kindness. That said, a small number on the busy tourist streets are working an angle. The shoe-shine routine is a classic: a man “accidentally” drops his brush near your feet, you helpfully hand it back, and suddenly he is polishing your shoes and presenting a bill for a few hundred lira.
The defence is simple. If something falls near you on a crowded tourist street, step around it and keep moving. Be polite, be friendly, but don’t accept unsolicited “help,” “free” gifts, or insistent guiding from someone you don’t know.

Don’t fight the crowd on İstiklal Avenue
Say Taksim and most people picture İstiklal Avenue, the long pedestrian boulevard with the little red tram trundling down the middle. You will almost certainly end up here, and you should, because there is a lot to see. But understand what you are walking into, especially after working hours, when the street fills with locals who are tired and just want to get home.
Don’t barge, don’t stop dead in the middle of the flow to take a photo, and don’t expect the easy pace of a quiet old town. Move with the current, keep an eye on your bag in the densest stretches, and you will enjoy the energy instead of getting swept up in it. Our İstiklal Avenue guide points you to the shops, passages and side streets that make the walk worth it.
Don’t assume tap water is for drinking
One small thing that trips up a lot of first-timers: locals do not drink the tap water. It is treated and fine for brushing your teeth or making coffee, but almost everyone here drinks bottled or filtered water, and so should you. Large bottles cost next to nothing at any corner shop, and many hotels leave a couple in the room. It is a tiny habit that saves you an unpleasant day.
Get these nine right and Istanbul rewards you. Slow down, cross to the other continent, settle the price before you eat, and let the city run at its own rhythm. That is when you stop being a tourist getting hustled and start being someone the city quietly lets in.
