Many of Istanbul's highlights are within walking distance of each other, but for longer journeys, travelers can opt to use public transportation like metro, tram, or bus. A metro journey costs $0.50, while tram and bus fares cost $1.50. Taxis are also widely available but can be more expensive.
If you have more time, you can add a visit to the Basilica Cistern or the Dolmabahce Palace. If you have less time, skip the Hammams or the sunset cruise, and focus on exploring more of the city's many mosques and historical sites. Don't forget to try the local food like doner kebabs, baklava, and Turkish delight while in Istanbul.
