The region of Loire is not far from Paris. Orleans is situated 130 km from the capital, and can be easily reached in one hour and a half drive on highway A10. Private vehicle remains the best way to visit the valley, since many of the castles are not well served by public transports. The French road system is efficient, with carriageways and highways in very good state and well signalled.
The most practical way to reach Loire is flying to Paris, then rent a car and drive all the way to Loire. Orly is the nearest airport. Those who want to fly directly to the region of Loire must be advised that the only city served by an airport is Tours ( airport of Saint Symphorien (TUF)), with international flights operated by a few low cost companies like Ryanair.
The Loire Valley is good connected to Paris through the high speed train TGV, which covers the length Paris-Montparnasse-Tours in approximately one hour. Alternatively, other towns in the region of Loire like Orleans Blois and Amboise are served by regular trains and can be reached in less than two hours.
