  Starting solo can feel daunting — a first group hike via the JARI Community is more reassuring (and more fun).

nature without a car.

Good news: from Paris you reach real forests by commuter train (Transilien, RER, TER). Your Navigo covers all of Île-de-France (as far as Fontainebleau): no car needed. Leave early on weekends to beat the crowds.

Fontainebleau, the top spot.

The Fontainebleau forest is the closest hiking paradise, reached by the Transilien Line R from Gare de Lyon (stations Bois-le-Roi, Fontainebleau-Avon, Thomery, Bourron-Marlotte–Grez).

• Easy loops start right from the stations.
• It's a world-famous bouldering spot (the legendary rocks) — crash-pad rental on site.
• For the keen: the GR®11 (Grand Tour of Île-de-France) and the Trans'Bleausarde (52 km over 2-3 days).

other forests & GR trails.

• The Rambouillet, Saint-Germain-en-Laye and Chantilly forests (all nearby) — reachable by train.
