The relevant shortest itinerary is a three days tour. There are options you can choose from – e.g. first and last days spent in Bucharest and the second day visit to venues located at max. 200 km drive – e.g. Peles Palace that you saw in the pictures, or wine and food tasting in a winery, or visit to a rural area, or boat drive on the Black Sea etc. Local gastronomy, wines and traditions are part of any tour.
