Use the metro.
The Paris metro system is safe, clean, and one of the most convenient and economical ways to get around—and simple once you get the hang of it. Pick up a map at the yellow information booth at most metro stations, a carnet of 10 tickets (€14.20, half price for kids under 12), and you’re good to go. Metros will take you within a few-minutes walk of almost anywhere in Paris, without having to contend with traffic or worry that you’re being taken for a ride. Paris’s metro stations are increasingly automated, and though the majority have manned information booths, a few do not, so have cash on hand. Ticketing machines are in English and will take cash or a credit card with a chip, and you can buy tickets with a standard credit card at any information booth.
