The Zadar airport is 12km away and they have organized buses and taxis that drive to Zadar. There is a bus station at the end of our street (2min walk from the house). The bus can take you directly to the old town/center, for 10kn (€1.33). Zadar has quite cheap taxis that charge 50kn (€6.66) for the first 5km. You can also walk everywhere because everything is very close.
