Leisure base opposite Bas Bugey. A pleasant stop, but strangely located between 2 nuclear power plants...

Beautiful cycle path, mostly shaded, unpaved but rideable (I ride it with 23mm tires), which follows the old line of the Chemin de Fer de l'Est Lyonnais (CFEL)

The Abbey of Ambronay was founded in 800 by Barnard de Romans, a soldier, an officer of Charlemagne, and a future saint canonized in 944. The abbey church, built on the ruins of the Carolingian church, features gargoyles, sculptures, and paintings that will amuse children with their fascinating details. The cloister is a space of serenity that invites meditation: your imagination may perhaps chase some ghostly figures of monks. The visit will end in the gardens where you will discover medicinal plants on the botanical trail. https://www.ain-tourisme.com/visiter-patrimoine/monuments-religieux-a-visiter-dans-l-ain/abbaye-benedictine-dambronay/
