Many tourists rely on the subway system to get around. However, while you are there to visit, why not see the city from the bus? Unlike other big cities, the buses in Paris are a first class ride for the same price. They are very clean and usually arrive every 7-10 minutes. The system is very easy to understand there are big maps and the lines are color coded and you can ask anyone on the bus to tell you where you should stop. Buses typically go faster than other cars too because they benefit from special bus lanes on all main avenues and boulevards throughout the city.
