On the Jarama front, taking advantage of the structure and characteristics of the terrain, the excavation of caves was common, from small individual shelters to large caves (like the one we can see on the “Secrets of the Greenway” route. Element 8) and tunnels that allowed entire squads or platoons to be housed, the installation of command posts, health posts, warehouses, etc. These excavations, on the one hand, allowed the troops to be hidden from the sight of the enemy and offered good protection in case of bombing, and on the other, they offered a certain degree of comfort to the soldiers who remained in them. These caves usually have many common elements, such as the existence of small holes to support camping equipment or personal objects or chimneys for the escape of smoke. After the Civil War, this type of caves have had various uses. One of them, and a very important one, was the cultivation of mushrooms, carried out until the mid-eighties of the 20th century.

These are excavations carried out on the ground to protect citizens during the bombings of the Spanish Civil War. Later they were used to plant mushrooms and other similar mushrooms. At present they are closed to avoid their destruction.

A unique and magical place a few km from the town of Chinchón. Its origin is artificial and is due to the mines that were exploited in the past for the extraction of sodium sulfate. Today you can visit them and contemplate their impressive size, and why not, imagine what it might have been like to work there a few centuries ago.

The Southeast Regional Park covers an area of 31,550 hectares in 16 municipalities of Madrid populations in constant expansion in the southeast of the capital, accentuating the peri-urban nature of the protected space, located in one of the most populated and industrialized areas of the Community of Madrid . A rich natural heritage of lagoons, wetlands, riverside forests, river groves and steppe hills make up a valuable set of ecosystems that are home to a unique flora and fauna in an environment of housing estates, roads, industrial farms and railways. A succession of strong contrasts that contribute to further elevate the environmental quality of the territory and the need to conserve these valuable wildlife refuges on the outskirts of the big city.

If you go from Tituñcia to Chinchón, and you choose to deviate just before the San Juan lagoons to see the chasm and continue along the new route ..., it's deadly !! 🤣🤣, I decided to do it and I don't regret it, but it's a Very very hard route, it is only 11 kilometers from the chasm to Chinchón, but go 11 km, it is a pass. I still recommend it. Break legs total !!! 🤦🏻♂️🤦🏻♂️🤦🏻♂️🤦🏻♂️
