Mont Griffon Summit

PATTONE HIKE - France

12 km

Join Pattone Club Randonneurs for a day out of the city at Mont Griffon in Yerres, just outside Paris. Expect wooded trails, green valleys and great views over the Yerres Valley, with a few climbs to spice things up. Come for the nature, stay for the beautiful people.

Meeting point: Gare du Nord at 09:00, where we'll take the RER D to Yerres together. The trip is covered by your Navigo pass, so no extra ticket needed. The hike starts right from Yerres station.

It's a 12 km loop, around 4 hours with breaks. To join, please add your Instagram handle when registering and make sure you follow @pattoneclubrandonneurs.

A few days before, we'll create a private group to share the final details. See you on the trails. 🌿
