At a weekly French-English conversation exchange group that we had started to attend, we learn about an informal hiking group, Ile de France Walks, that takes day trips every Wednesday to places within an hour or so of Paris. We sign up at http://idfwalks.blogspot.com to receive the weekly announcements.
