France
We arrived by TGV in La Rochelle and quickly found the busses to Ile de Ré in front of the station. They cost about 15 euros and they run the length of the island, stopping in the main towns. There are, however, different routes so be aware that some busses don't go to St. Martin, only the towns on the south coast. For example.
