Peña del Arco

The trail reaches a crossroads at the junction of the Fuente Nueva and Arco boulevards and turns left along the bottom of the ravine. The surface is excellent for running and the terrain is favorable. The tracks on the forest track run through the pine forest along the edge of the dry riverbed and reach the natural wonder of Peña del Arco, the stellar spot for the trail through an arch of calcareous rock that cross the ravine from side to side. There are also limestone walls, small passageways, loose blocks and tormos, which are the characteristic mushroom-shaped karst formations sculpted by dissolving water. The lower part of the stone tower is usually narrower than the upper part because it has suffered a greater incidence of erosion due to humidity and water currents. At the entrance to the rock arch there is a sign with details and drawings of the karstic modeling of the limestone rocks.
