Istanbul's public transport network is large, genuinely useful for visitors, and unified under a single card: the Istanbulkart. It works on trams, the metro, the funiculars, city buses, and — usefully — the public ferries, which double as one of the best sightseeing rides in the city for the price of a bus fare.
Getting your card
Istanbulkart machines are at every metro and tram station, the airports, and many ferry terminals. The machines have an English-language option, take cash and card, and issue the physical card on the spot for a small one-off fee, separate from the travel credit you load onto it. Keep the receipt if the machine gives one — it occasionally helps with balance disputes.
One card can be tapped for multiple people in a group — you don't need one each, you just tap it again for each rider passing through the gate, and its balance is used down accordingly.
What it covers
- Trams (T1 etc.) — the line most visitors use most, running right through Sultanahmet.
- Metro & Marmaray — including the cross-Bosphorus rail tunnel, one of the few ways to cross under the strait by rail.
- Funiculars — short, steep connectors like the one linking the waterfront up to Taksim.
- Buses — the widest-reaching but least visitor-friendly network; route-planning apps help a lot here.
- Public ferries (Şehir Hatları) — commuter boats across and along the Bosphorus, genuinely one of the best things to do in the city, not just a way to get somewhere.
Transfers
Within a set time window after your first tap, connecting to another form of transit costs less than a fresh fare — the discount stacks over a few transfers, then flattens out. In practice: don't be afraid to break a cross-city trip into a tram + ferry + funicular combination. It's usually cheaper than it looks, and each leg tends to be more pleasant than a single long bus ride.
Walking vs. transit in the old city
Sultanahmet's core sights are close enough to walk between — Hagia Sophia to the Blue Mosque is a few minutes on foot. Save the Istanbulkart for getting to the old city, then crossing to Beyoğlu, Beşiktaş or the Asian side, where distances genuinely need transit or a ferry.
