The city is efficiently served by buses and trolleybuses from 5.30 am or 6 am to midnight; Sunday services are less frequent. Single-trip tickets cost €1 from the driver; €0.64 if you have a Vilniečio Kortelė (an electronic ticket sold at kiosks; see www.vilniusticket.lt for details); or nothing if you have a Vilnius City Card with public transport included (sold in tourist information centers). Fare evaders risk a fine.

All routes 

Vilnius is generally easy to navigate by car, and not too busy, but the traffic burden is getting heavier each year. Street parking around the center can be hard to find and is expensive: rates (from 8 am to 8 pm) run to as much as €2 an hour. The rate is identified by a color code system (blue is the most expensive) and tickets need to be bought from a machine and displayed on the dashboard.

Avoid parking on unlit streets overnight; car break-ins are not unknown. Cars are not permitted in parts of the pedestrian Old Town.

We recommend you to take a taxi from the airport to the hotel as the most comfortable option. The price from the airport to the hotel would be about 12-14 euro depending on the company. It’s cheaper if you call and order a taxi, not take the one from the airport.

The standard rule is to make sure the meter is running and set to the correct tariff (generally 1 most of the time and 2 after midnight) before setting off.

eTransport  is an app where you can easily order a taxi and you will have a choice if you want to pay cash or card.
Taxify is also an app, very similar to Uber, just cheaper.

Vilnius is becoming increasingly bike-friendly, although bike lanes are rarer outside the Old Town and along the banks of the Neris. Orange Cyclocity stations dot the city, the tourist office has free cycling maps, and BaltiCCycle (www.balticcycle.lt) is good for ideas and information.

Cyclocity Bikes can be easily hired and returned at the 37 orange Cyclocity stations across Vilnius. Either credit cards or Cyclocity Cards (available by advance subscription) can be used to hire a bike. A three-day ticket is €2.90.

Velo-City This well-established bike-hire operation on the edge of the Old Town has decent, well-maintained bikes.
