The Paris metro is one of the densest networks in the world, with over 300 stations across 14 lines, each identified by a number and a color. It generally runs from 5:30 am to just after midnight, with later closing on Friday and Saturday nights. The RER complements the network, connecting central Paris to the suburbs and the airports over longer distances than the regular metro.
The network
Metro lines are numbered 1 through 14, and every station displays the full network map along with possible connections. Trains run frequently during rush hour, less often later in the evening.
Tips
Free paper maps are available at ticket counters. The RATP app can plan a precise route and gives real-time updates on disruptions. Before heading out, it's also worth checking for any announced strikes, which can sharply cut the number of trains running.
