Tips from the Community

Alvaro Hernandez
September 2, 2025, Lavender Fields at Collado de las Palomas

The Las Palomas Pass enjoys a spectacular setting. The greenery of the surrounding alpine meadow is broken by the sharp edges of the dark slate that sprouts from the ground. In autumn, the valley is adorned with ochre and reddish hues. In spring, the intense violet of the lavender shades the green of the landscape.

The Pontón de la Oliva is a Spanish dam located in the Ayllón mountain range, northeast of the Community of Madrid and northwest of the province of Guadalajara. It was built in 1857 and is currently disused. This dam is the sixth and last in the course of the Lozoya River, and is the oldest of the entire system of dams and canalizations of the Canal de Isabel II. This canal supplies drinking water to Madrid and a large part of the community. The height of the Pontón de la Oliva Dam is approximately 30 meters. If you are interested in exploring the area, there are routes that take you to the Cárcavas de Pontón de la Oliva, a curious geological formation in the Community of Madrid. In addition, you can enjoy a route along the Pontón de la Oliva to the Lozoya River, which offers impressive views. I hope you find this information interesting! 😊

The Puentes Viejas reservoir is located in the middle course of the Lozoya River, in the Sierra Norte (Madrid). It belongs to the Canal de Isabel II reservoir network and is the third reservoir in the direction of the current that the river passes through.

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.
