How Much Time Should You Spend in Krakow? 3 days in Krakow is the perfect amount of time to tour Wawel Castle, visit the top sights in the Old Town, get a history lesson in Kazimierz, and day trip to Auschwitz-Birkenau. If you have less than 3 days in Krakow, you can do this same itinerary, with some modifications.
