Etymology of the name

The name, Sierra de Guadarrama (Guadarrama Mountains), is taken from the Guadarrama river and the town of Guadarrama
Guadarrama

Guadarrama is a town in the Community of Madrid in Spain.Pop: 13032 , approx. 60000 .Co-ordinates .Founded by the Arabs, Guadarrama achieved the status of "villa" under Ferdinand II of Aragon on November 22, 1504....
, both of which are located in these mountains. The word Guadarrama itself is derived from the Arabic words for sandy riverGuad from wadi, meaning river, and arrama from al-rama, meaning sandy. The name was affixed to the river (and the village and the mountains) during the Arab occupation of Spain (722-1492 CE), and the name remained in currency even after the Reconquista

Principal cities and towns

The Sierra de Guadarrama is surrounded by prominent population centers which feature many second residences, occupied during holiday periods.

, characterized by considerable temperatures changes between summer and winter and a very dry summer. But, as in any mountainous zone, the climate on the mountains proper changes markedly with increases in height, and for that reason it is necessary to differentiate discrete climatic zones.

Between 800 and 1,400 m, the average, annual temperature is between 10 and 11 °C, with a high summer temperature of 28 °C and a low in winter of -6 °C. Average, annual precipitation

 is between 700 and 800 mm, a large portion of which accumulates in non-summer months. At this elevation, much of the precipitation is in the form of snow, falling between December and February, although there are always exceptions, and the snow rarely remains unmelted for more than three days. It is in this region that all cities and the majority of people live; this also means that of all distinguished elevations, it is the most susceptible to damage from human traffic and intrusion.

Between 1,400 and 2,000 meters, the average, annual temperature is between 8 and 9 °C, with a high summer temperature of 25 °C and a low in winter of -8 °C. Average, annual precipitation climbs with the height to between 900 and 1,000 mm, much of which is likewise laid down during the non-summer season and is in the form of snow, but laid down between December and April. Much of the snow remains on the ground for the duration of the winter — especially on the range's north slope.
Niemba Engelante
Between 2,000 and 2,428 meters, the average, annual temperature is between 6 and 7 °C, with a high summer temperature of 22 °C and a frosty low in winter of -12 °C. Average, annual precipitation is between 1,200 and 2,500 mm, mostly in the form of snow laid down between November and May which remains the winterlong and into the spring.

In summary, the climate of the Guadarramas is quite humid, more so than that of the rest of the Meseta Central (Central Plateau), and generally cold, which increases with altitude. In the peaks the wind is usually very intense and thunderstorms in the mountains are more frequent than in the plateau.

  • The Parque Regional de la Cuenca Alta del Manzanares ("High River basin Regional Park of the Manzanares"), located in the Community of Madrid; the first Sierra de Guadarrama zone to receive protected status. When the designation was first granted it included only La Pedriza (an area including a number of peaks, valleys and rivers in the Guadarramas), but later it was extended to cover the Monte de El Pardo — a densely forested area to the north of Madrid, covering more than 470 square kilometres (181 mile²).

Myths and legends
