It is better to get a Carnet de Tickets (10 tickets) when you’re planning to take the subway. Here are the prices :
- 1 Carnet de Tickets : 14,5€
- 1 ticket : 1,9€
- a ticket can be use for a one-way trip with subway (multiple transfers are allowed without going out) and only one transfer with the bus (transit from one bus to another bus), transit time can’t be over 90 minutes.
If you come to Paris for only a 2 or 3 days, it’s better to get a Carnet de Tickets. But keep in mind that Paris is beautiful and a small town, the distance between stations is short and you can do it on foot almost everytime.
