Enjoy Blois , plenty of info inside the posts above. By car is about 1h30 from Paris . Get on the A10 direction Bordeaux and go out on exit/sortie Blois, about 170 km or 105 miles or go on the no tolls road N152 direction Blois-Orleans for about 180 km or 112 miles. If no GPS in the car use viamichelin for the routing online. By train from Gare d’Austerlitz Paris to the station of Blois-Chambord in about 1h40 or from Gare Montparnasse Paris on TGV to Vendome and then to Blois by taxi 30 km or to gare Saint-Pierre des Corps just outside Tours and then 30 minutes on taxi to Blois.
By bus OuiBus takes you from Roissy CDG or Gare de Bercy in Paris here: https://www.ouibus.com/
