Easy day trip idea from Lyon: - Start the day by visiting 2 incredible medieval villages: Crémieu and Pérouges - Tour the beautiful Ambronay Abbey (best visited through a guided tour, but they don't run often) - Learn about the cooper industry at the Cuivrerie du Cerdon (you can get a package ticket to visit the Silks Bonnet Museum as well) - Finish the day by touring the Cerdon Cave (if you have kids check out the activities they offer). Alternatively you can visit the La Balme Cave, closer to
