It is the gateway to the provinces of Parinacota and General Lagos in the altiplano, as well as the international road Arica-La Paz (Bolivia). Leaving the city of Arica to the north, at the mouth of the Lluta River, there is a bridge (chaca-lluta in Aymara) and a roundabout with the detour to the high plateau.
The road goes along the Lluta River, which crosses two bridges until finally reaching the small town of Poconchile.
At its entrance you can see numerous hills adorned with geoglyphs because the valley was populated by Indians from the earliest times, we must remember that it is one of the natural outlets of the highlands towards the sea.
As we get into the road, the gorge closes and finally begins to climb with a steep slope that gives us spectacular views of the valley down.
