Hi,The plan is to drive from Lyon to various via ferratas in the mountains near Grenoble and Chambery. If you are not keen on via ferrata, you could change this to a hike. Near Grenoble- Via Ferrata de la Roche Veyrandhttps://maps.app.goo.gl/gCsDTtnu9QgBeBfS9. Near Chambery Via ferrata - Rocher de Cornillonhttps://maps.app.goo.gl/fvkLcbR74SVkTcWy8. We can try for this as well Via Ferrata Yves Pollet-Villardhttps://maps.app.goo.gl/WfazbC4ZxBzYkrk19 Or simply do some other hikes in the area. You can either join me at Luxembourg Gare or meet directly at Lyon.Best Regards,Joseph
