Touring Tours is incredibly easy , as there are multiple modes of convenient transport to, from, and within the city.

The TGV super-rapid rail keeps the city at arms length from Paris—just a fifty five minute ride—and thus facilitates easy access to airports d’Orly and de Gaulle.  (One can, however, take an intra-Euro trip into the Val De Loire, located only a few miles north.)

Bus service is not particularly frequent, as it is intended for more regional use and thus does not reside solely within city limits.    

Driving around Tours is a wonderful way to check its various musea, chateaux, and cathedra and makes for wonderful, private daytrips throughout the Loire Valley.  Parking in Tours is easy, and highways are generally well-maintained and are not difficult to navigate.

Getting to the local chateaux is easy and cheap on public transport from Tours. There's a train from Tours station to Chenenceaux - although this is replaced by a bus service from the station when there are works on the line - which takes you almost directly to Chenenceau chateau, one of the most beautiful in the region. Both Blois and Amboise are also easily reached by train and are well worth a visit. Villandry and Azay le Rideau are reasonably close, but neither is served by a train or bus service. It's worthwhile taking a minibus tour from outside the Tourist Office opposite the railway station, which offers a half-day trip to both chateaux for 19 euros per person. Cycling is also possible, with well-marked paths along the Loire to Villandry (21 kilometres away from Tours) and beyond.
