On the back of a mountain in the south of Mantana, there is the village of Onies at 1,144 m.

Up to the year 1928, Oines used to be an autonomous municipality, afterwards it came to join San Lorenzo. Onies can be reached on a road from Mantana and is located on a steep slope. If you would like to go promenading, come and see the Aster Stöckl, a chapel that is dedicated to Maria della Neve. Also the Anton Schwingshackl trail or a walk to the Alpine pastures of Rina are highly recommendable.
