Pontón de la Oliva Dam and Cliffside Pathways

Highlight • Monument

The Pontón de la Oliva dam, built during the reign of Isabel II, is the oldest dam in Madrid. It is built in limestone, the rock that we find in the surroundings.
Since the mid-eighteenth century there was already the idea of supplying water to the court from some of the mighty rivers of the Sierra de Madrid, such as the Lozoya. It is in the middle of the 19th century, when the olive pontoon was selected as the most suitable place to build the first dam in Madrid.

Pontón de la Oliva Dam

Highlight • Monument

Built under the reign of Isabel II, it is the oldest dam in Madrid, being the last on the course of the Lozoya River. This dam, 27 meters high, made of limestone, was inaugurated in 1856 as the beginning of the water supply project for Madrid, the new capital of the kingdom of Spain, which was growing considerably in population. Currently disused due to permeability problems caused by the poor choice of its location, today it belongs to the historical heritage of the Sierra de Ayllón, being a place visited by climbing enthusiasts and traveled by hikers and cyclists.

Close-up view of Las Cárcavas del Monte Guadarrama

Highlight • Gorge

The gullies are the sinkholes produced in rocks and soils of places with slopes due to the avenues of rainwater. These produce the so-called remounting erosion. They occur only in the clay-type substrate, if there are two or more gullies that advance parallel in a straight line, it is called rills.

Las Cárcavas - Pontón de la Oliva

Highlight • Gorge

This Martian landscape has been caused by strong water erosion on the clayey slope, forming these ditches that make up a science fiction landscape. It is also beautiful because of the surrounding environment, be careful and respect the signs, there are paths where it is forbidden to ride a bike so you will have to get off it.
