The central old quarter of Vilnius is compact and most of the sights visited on foot. Those who would prefer to take in the sights in a more leisurely manner can make use of the city's efficient network of buses and trolleybuses; fares can be paid on boarding or tickets bought at a discount from newspaper kiosks.Most visitors prefer to make use of taxis, which are relatively cheap, although it is wise to ensure the driver has switched on the meter before leaving on the journey, or to negotiate a fare before setting off.Taxis can be hailed on the street, ordered by telephone or found at ranks at strategic spots in the old town. Self-driving in the city isn't recommended because of heavy, undisciplined traffic. All the large international car hire companies have offices in the city and at the airport.Visitors to Vilnius should be aware that, although the city is generally very safe, petty theft and pick-pocketing can unfortunately be a problem on public transport. People are also sometimes targeted while walking around. So although it is a great destination to traverse on foot, try not to walk alone at night, or display conspicuous wealth while getting around in the city.
