If you want to go to Disneyland from one of the Paris train stations or spend a day in Paris, you can use the RER. RER stands for Réseau Express Régional and is comparable to a subway.
Disneyland Paris is located on the RER A line. The stop is called Marne-la-Valée / Chessy Parcs Disneyland.
It takes about 35 minutes to get to the center of Paris with this train, which is integrated into the metro network of the metropolis. A train runs every 5-10 minutes during peak hours, and every 20 minutes during off-peak times.
To use the RER, you need a ticket that you can buy directly at the RER stations and metro stations in Paris. For the Paris-Disneyland route or vice versa, you need a ticket that ranges from zone 1-5.
