What Is the Difference Between the RER and the Metro in Paris?

By Alice Nichols

If you’re planning a trip to Paris, you may be wondering about the best way to get around the city. Two popular options for transportation are the RER and the Metro. While they may seem similar, there are some key differences between the two systems.

What is the RER?
The RER, or Réseau Express Régional, is a rapid transit system that serves both Paris and its surrounding suburbs. It consists of five lines, labeled A through E, and operates similarly to a commuter rail system. The RER trains are larger than those on the Metro and can travel longer distances, making them a good option for those traveling to destinations outside of central Paris.

Key features of the RER:

  • Five lines (A through E)
  • Serves both Paris and its suburbs
  • Trains are larger than those on the Metro
  • Can travel longer distances
  • Operates similarly to a commuter rail system

What is the Metro?
The Metro is a rapid transit system that serves primarily central Paris. It consists of 16 lines labeled 1 through 14 (with two additional lines labeled 3bis and 7bis) and is one of the busiest metro systems in Europe. The trains on the Metro are smaller than those on the RER but run more frequently.

Key features of the Metro:

  • Serves primarily central Paris
  • Consists of 16 lines labeled 1 through 14 (with two additional lines labeled 3bis and 7bis)
  • One of Europe’s busiest metro systems
  • Trains are smaller than those on the RER but run more frequently

Differences between the RER and the Metro:
While both the RER and the Metro are part of Paris’ public transportation system, there are several differences between the two. The RER serves a larger area, including suburbs outside of central Paris, while the Metro primarily serves central Paris.

The RER trains are larger and can travel longer distances than those on the Metro. However, the Metro runs more frequently and is one of Europe’s busiest metro systems.

Which one should you take?

The answer to this question depends on where you’re going in Paris. If you’re traveling to destinations outside of central Paris, such as Disneyland or Versailles, the RER may be your best option. However, if you’re staying within central Paris, such as near the Eiffel Tower or Notre-Dame Cathedral, the Metro will likely be your go-to mode of transportation.

Tips for using public transportation in Paris:

  • Purchase a Navigo pass for unlimited rides on both the RER and Metro
  • Avoid rush hour if possible to ensure a more comfortable ride
  • Be aware of pickpockets on crowded trains
  • Check schedules and plan your route ahead of time to save time and avoid confusion

In conclusion, while both the RER and Metro are part of Paris’ public transportation system and provide efficient ways to get around the city, they do have some key differences. Understanding these differences can help you choose which mode of transportation is best for your needs during your visit to this beautiful city.
