Brest is served by a regional airport, located to the north-east of the city. It's used mainly by Air France for its domestic routes (Paris-CDG, Paris-Orly, Marseille), but also by Easyjet (Lyon), Ryanair (Marseille) and other companies for regular routes (Bordeaux, Lille, Toulon, Barcelona) or special services. A bus shuttle service connects the airport to the Brest tramway station at Porte de Guipavas several times per day. The trip takes about 15 minutes. At Porte de Guipavas, you can take the tramway (Line A, towards Porte de Plouzané) to the city centre. The ticket costs €1.35 and is valid for 1 hour on any Bibus service (airport shuttle, tramway, bus routes). Alternatively, if you are planning on making some rounds on the same day, you can by a daily ticket, which costs €3.70 and is valid until the end of the day on any Bibus service.
The [Brest tramway http://www.letram-brest.fr/] extends for 14.3 km with 28 stops. Its sole line, Line A, is a Y-shaped service connecting Porte de Plouzané (western Brest) with, alternately, Porte de Gouesnou and Porte de Guipavas (northeast). Fourteen regular bus routes, all connected to the tram, complete the network. Both the tramway and the regular bus routes, as well as the shuttle bus to/from the Brest Bretagne airport, are run by [Bibus http://www.bibus.fr/]. A single ticket costs €1.35 and is valid for 1 hour on any Bibus service. A journey ticket costs €3.70 and is valid until the end of the day for one person on week days and up to 4 people on weekend. These tickets can be bought to the bus driver or on the automatic machines at the tram stops.
Much of Brest was all but obliterated during WW2, and therefore it is not the most beautiful of cities, but there are a few attractions that are worth an hour or two.
