A must-see spot in the region, magnificent and impressive, but be careful of the incredible number of tourists in case of good weather during the day, choose to go there early in the morning!

The rock of this natural tunnel is limestone. It was erosion that made it possible to pierce the rock and thus created a window that was, to say the least, original.

Great hike with magical landscapes, however, there is a big downside on the last 3 kilometers on the departmental road with heavy rolling. Avoid with children who are too small and not used to hiking. Some passages are not easy, do not leave without suitable equipment (especially shoes)
