If you have a few days in Andorra, then you can easily visit most of the main villages by the local bus service called the Cooperativa Interurbana Andorrana, S.A. (http://www.interurbana.ad...)
There are 8 main bus lines or 'linies', and all of these pass through Andorra La Vella. The fare is anything from 1â¬20 to two or three euros depending on how far you are going. Drivers will provide change. For the towns nearest to Andorra La Vella, the service is very regular, and as frequent as every 10 minutes during the day. If you are travelling to outlying rural places like Canolic, there are only 2 or 3 buses per day.
The lines are:
L1 Sant Julia de Loria - Escaldes-Engordany
L2 Andorra la Vella - Encamp
L3 Andorra la Vella - Encamp - Canillo
L4 Andorra la Vella - Encamp - Canillo - Soldeu
L5 Andorra la Vella - Encamp - Encamp - Canillo - El Pas de la Casa
L6 Andorra la Vella - La Massana - Arinsal
L7 Andorra la Vella - La Massana - Ordino
