In the small Pyrenean state of Andorra, public transport is provided exclusively by regular bus services. In addition to some intercity connections, also to the two neighbouring countries Spain and France, there is a range of urban lines in the capital Andorra La Vella, which connect the various districts and neighbouring towns throughout the Principality and link them with each other. In some cases, considerable differences in altitude have to be overcome.
Since the last restructuring of the network, during which the L3 line was dropped, the lines L1, L2, L4, L5, L6, LC (Linea Circular = ring line) and the é line are currently in operation. Responsible for the operation are the two companies Coopalsa (UT founded by Cooperativa Interurbana Andorrana SA + Transpisa) – for the L2, L4, L5, L6 and LC – and Autocars Nadal for the lines L1 and Express Bus. The frequency varies, line é operates every 10 minutes during the day, lines L1 and L2 every 10-20 minutes and the other lines every 30-60 minutes. At weekends and on the eve of public holidays, a night bus service runs until 05:00. To Escaldes Engordany, there is also a Bus on Demand service with minibuses manufactured by Karsan. A mix of midibuses and 12-metre buses from different manufacturers is used on the other routes.
Special services are added during the ski season. The lines are designed so that the user can reach the foot of the slopes or the cable cars of Encamp, Canillo, La Massana and Arcalís from any point in Andorra. In the southern valley, the L1 connects to all lines and the Express Bus connects Escaldes Engordany directly. The central transfer point in Andorra la Vella is the Estació Nacional de Autobusos.
Since July 2022, the bus service has been largely free of charge, mainly for permanent users, i.e. primarily for Andorran residents. The only prerequisite is the possession of a corresponding season ticket, which can also be used digitally as an APP on the mobile phone.09.11.2023
