The natural park called Los Cerros de Alcalá, is the main green area in Alcalá. It is a great place for hiking or riding a bike without leaving the city.

If you live close to the river Henares, you have probably noticed the small hills without urban development on the other side of it. This is the natural park called Los Cerros de Alcala, and it is the main green area in the city (which is not to say much though, since Alcala has a general lack of green areas).

The origins of Los Cerros de Alcala Natural Area

This natural park, which stretches over 806 hectares (1 hectare is approximately as large as a soccer field), is both the result of the erosive action of the river Henares and the action of man.

The following video is from the City Hall of Alcala. It explains and illustrates the origins of this green area:

 

The hills were deforested by the population of Alcalá in order to use the wood for cooking and heating, which enhanced the erosion of the hills. To avoid this, several areas of the park have been replanted over the last decades. Other parts of the park were used for harvesting, and there was even a large landfill, which was closed several years ago and covered with earth and replanted to recover the area.

What to visit in Cerros de Alcala Natural Area?

During Ninth century, in the muslim period of Alcala, a small defensive tower was built on top of one of the hills, which later developed into a larger fortress. Those were hard times for living in Spain due to the constant raids and fights, and therefore the inhabitants of Alcala abandoned the old roman settlement (Complutum), for the safety of the hills and the fortress.

The arabic fortress Al-Qalat

In fact the name of Alcalá, derives from the arabic Al-Qalat (fortress). You can still visit the ruins of the fortress, although, in our opinion, they are not very well taken care of.

If you hike or ride your bike in the park you will notice the large amount of caves, some of them were used for harvesting mushrooms (you can still see paint on the cave walls signalling the harvesting time)  or as temporary shelters during the Spanish civil war.

If you are lucky, you can even become rich on your visit to the park! As the legend goes, one arab ruler hid his treasure in one of the caves, before departing south due to the christian reconquest.
