Istanbul is not a city you will ever totally explore in the space of one visit, so if you want to see the best of it, you need to plan ahead. One of the top tips for visiting Istanbul is simply to make sure you have a reasonable amount of time. It’s also worth mentioning that this city is HUGE. You will hit traffic at every turn, but you will also see buildings dating back to around the 1400s. There is more history here than perhaps anywhere else in the world, and seeing it for yourself is a real must-do on any visit to Turkey.
