아르베타‬에서 가장 멋진 ‪8‬개의 천연기념물

Muslim castle built on a firm rock. Impregnable. for the defense of the Tagus River.

Beautiful place, surrounded by nature from all angles.

A curious place where the collapse of the side cliffs, as a consequence of the Lisbon earthquake, closed the Tagus River for several days, interrupting the flow of water. Today, there are still a large number of huge rocks at the bottom of the Tagus. It is worth visiting.

The Valtablado del Río bridge crosses the waters of the Tagus in an area full of poplars. The great width and shallowness of the river, added to the shade provided by the trees, creates a privileged bathing area on hot days.

Wonderful bridge located at the entrance of Valtablado with a wonderful well

What a great and interesting area. The rocks, arch, and trail in this area are wonderful for walking or running. At the entrance to the rock arch there is a sign with details and drawings of the limestone rocks.

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.

Summit with privileged views of the karstic system that occurs in the Hundido de Armallones.
