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.
