Very beautiful village with character, entirely made of stone; from the village, you can see the Madonna of the Larina Archaeological site.

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)
