This dramatic canyon is located to the north of the Rodellar Valley, in the heart of the Guara Natural Park.

The karstic, limestone rock shows effects of erosion in the form of small grooves and narrow furrows that are separated by ridges, also known as “limestone pavements.” The karst effect is also at work under the surface where underground rivers flow for tens of kilometres. In addition there is an abundance of underground lakes, siphons, chasms and caves that feed freshwater springs, one of which provides the steady flow of water for the Mascún River.
