The historic core of Isfahan — the area around Naqsh-e Jahan Square, the bazaar, and the bridges — is compact enough to explore entirely on foot. Most of the main sights are within a twenty-minute walk of each other, and the streets between them are interesting enough that walking is the obvious choice for daytime sightseeing.
Taxis: For longer distances — reaching the Khaju Bridge, the Jolfa district, or areas further from the centre — taxis are the practical option. Isfahan has both metered taxis and shared taxis (savari) that run fixed routes. Ride-hailing apps (Snapp and Tap30) work well in Isfahan and are often easier to use than negotiating fares.
Metro: Isfahan's metro system has two lines but currently serves the tourist areas poorly — the nearest station to the centre is a walk from Naqsh-e Jahan Square. It is useful for reaching the bus terminal and the university area, but most visitors will not need it.
Cycling: Bicycles are available for hire near the main tourist sites. The riverside path along the Zayandeh makes for a pleasant ride between the bridges.
Driving: Traffic in the old city is heavy and parking is difficult. It is not worth renting a car for exploring Isfahan itself, though a car is useful for day trips to Natanz, Kashan, or Varzaneh.
