If you are just staying in and around the town itself, you’ll be fine, but making even short excursions to places like Rovinj is difficult to plan ahead without relying on printed timetables at bus stops. A car is extremely useful for heading along the Adriatic coast towards other great destinations such as Zadar and then Split, or even as far as Dubrovnik. Check locally for one way rental deals – generally this is possible within Croatia, but often at a price.
Do you need a car in Pula? Yes!
