Domestic and international flights leave from Aéroport Biarritz Pays Basque. Chronoplus (www.chronoplus.eu) Line C buses run from the train station in Biarritz, while Line 14 leaves from near the Biarritz tourist office. Both run every half-hour or so and take about 10 minutes. A single fare costs €1.
Buses run frequently between Bayonne and Biarritz. They are much cheaper than taking the train since a bus ticket costs about the same as you'll pay to get from Biarritz' train station to its town centre.
Transports 64 line 816 buses travel down the coast to St-Jean de Luz, Urrugne and Hendaye; there's also an express service that runs three times daily. The fare is a flat-rate €2, and buses leave from the stop near the tourist office beside square d'Ixelles.
Buses to Spain, including San Sebastián and Bilbao, also depart from that stop.
All trains to Biarritz only stop at the train station about 3.5km southeast of the town centre (the old, central Gare du Midi station is now a cultural centre). Chronoplus bus 10 runs regularly into the city centre, and bus C serves central Bayonne.
Trains serve: Paris Gare Montparnasse (€50 to €109, 4¼ hours, five daily), Bordeaux (€35 to €50, 2¼ hours, 10 daily), St-Jean de Luz (€4, 15 minutes, 15 daily) and Hendaye (€6, 35 minutes, 15 daily).
