The Peney viewpoint overlooks Lake Sylans, on which it offers a beautiful view. Classified since 1909, one can distinguish on its banks the ruins of the old ice factories which commercialized the ice extracted from the lake until 1917. The passage is located at the level of the tunnel of the same name.

The Marron ponds are named after a family from Brénod, it is not a reference to the color of the water. Only one of them remains filled with water all year round. This one served as a water reserve and fishing spot for the monks of the Meyriat abbey. In spring, a multitude of water lilies cover the surface.

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/

Beautiful, simple, easy walk; lots of traffic noise on the "road" section, a bit of a shame, but the color of the water is magical

Unfortunately I was unlucky with the weather, but even as I drove past the place looked very nice, lots of grass and a place to swim.
