To reach Disneyland Paris from central Paris, you must take the RER A (Regional Express Network) train. Specifically, you need to board a train on the A4 branch headed toward the eastern terminus, Marne-la-Vallée/Chessy. The station is located directly at the gates of the Disney Parks and the Disney Village, making it incredibly convenient. The journey from major central stations like Châtelet-Les Halles or Gare de Lyon takes approximately 35 to 45 minutes. It is important to ensure your ticket covers Zones 1-5, as a standard t+ metro ticket is not valid for this suburban journey and could result in a fine. Trains typically run every 15 minutes from early morning until after midnight, providing plenty of flexibility for park hopping. You can easily spot the correct train on the platform display screens by looking for the "Mickey Mouse" icon or the Marne-la-Vallée destination name.
