Ljubljana is a small, compact city that is easy to explore on foot, especially for those intent on appreciating the architecture. The next best option is the inexpensive and efficient bus service. To ride the bus, passengers first need to purchase an Urbana card from self-service stations near the larger bus stops and load it with credit.Cars are a liability in the city, which is largely pedestrianised, and parking is at a premium. Bicycles provide a fun and convenient way of getting around, available to rent for a nominal fee and small deposit. Taxis are available and a good option after dark, when the bus service is radically reduced.
