You can have a taste of Colorado in central Italy, in the Mt. Sibillini National Park. The place is called "Le lame rosse" (the red blades) and it is near the nice Lake of Fiastra, and it can be reach with an easy 1 hour hike.
This barren landscape appears very unexpected at the end of the trail, which runs under the bush.
The pinnacles can be up to 50 meters high.
Such types of rocks formations are very unusual in Italy.
