My phone was dead, and the tour was 38 km long with 1,100 meters of elevation gain. The terrain was very wet and snowy. In dry weather, the hike must be even more enjoyable, but you need to be in good physical condition; there are some really nice sections with beautiful views.

The Marron ponds have been labeled “Sensitive Natural Spaces” since 2015. They take their name from a family from Brénod. They were created around 1120 and once served as a water and fishing reserve for the monks of Meyriat Abbey.
