On foot: The Old Town is compact — you can walk end to end in twenty minutes — and most of the major sights are within a comfortable distance of each other. Cobbled streets are the norm, so comfortable shoes matter.
Bus and trolleybus: Vilnius has a good bus and trolleybus network serving the wider city. Tickets (around €1) can be bought from the driver (more expensive) or validated from a card at the machine on board. Single-journey and day passes are both available. The useful routes for visitors run along Gedimino Avenue and connect the old town with the main railway and bus stations.
Taxis and rideshare: Bolt (formerly Taxify) and Uber both operate in Vilnius and are the easiest way to get around outside the walkable centre. Fares are very reasonable by Western European standards — a short trip in the city centre rarely exceeds €5. Booking via the app avoids any possibility of overcharging. Street taxis are also metered and generally honest.
Cycling: The city has a bikeshare scheme (CityBee and others) with docking stations around the centre. The old town's cobbles make cycling uncomfortable on main routes, but the riverside paths along the Neris and Vilnia are good cycling terrain.
Car: Driving in the old town is restricted. Street parking is metered in the centre; multi-storey car parks are available near the old town perimeter.
