Here’s an idea to get out of town, hop on the train with your bike to get out of the city a little ways. Then pedal to another station to ride back to Paris. You can travel with your bike on the SNCF Transilien (suburban) trains on weekdays before 6:30, between 9:30 and 16:30 and after 19:30 and all day on Saturdays, Sundays and holidays, for no extra charge! And now that Navigo covers all zones there’s nothing to stop you.

- Longer – 13 km begin at Evry Val de Seine, end at Montgeron Crosne. Ride between the valleys of the Seine and the Yerres, then in the Senart forest known for Druids, the kings of France and huge multi-century oaks.
