The Luchi valley is a particular geological formation found in the Caramanico area. Its name may originate from Lucus, sacred wood, and it is truly a magical place.
Just beyond the village of Saint Tommaso, you descend into this beautiful valley which is surrounded on one side by a rocky cliff called Saint Lucia.
It is this cliff face, together with smaller formations, which makes up the peculiar geology of this area.
These formations surfaced after millions of years of erosion, and also due to subsidence. Along side these rocky formations, there are broad terraces.
Thanks to the natural terraces and the fertility of the land, the place has always been cultivated with ease and chosen as an ideal place to live. The ruins of a nearby medieval castle give credence to this fact. Continuing to walk through this valley you arrire at a river and another miracle of this place is revealed: here the river eroded the limestone forming splendid pot holes.
