I am considering purchasing a Paris ComboPass from the paris.conciergerie.com website. It provides unlimited free rides within 3 zones on all public transportation. I'm not sure if the zones are Metro zones or bus zones, or if there is a difference. Does anyone know how many zones are between Eiffel Tower/Rue Cler (Zone 1 ?) to Montremartre? Does anyone have a recommendation for the "easiest" way to travel from Rue Cler (or that area) to Montremartre?
Thanks!
