we are a group of 7 young adults going there at the end of august. i hope you can help cause i am getting a bit frustrated with all the passes and their value duration... :')
There's no group ticket option for adults for the Paris Metro or trains. The only group options are for school groups.
Generally, the best option is the Navigo Week pass if you're arriving Monday-Thursday. Otherwise, consider the Navigo Easy with a pack of ten tickets + any airport bus tickets you may need to get to Paris.
