The Meseta Central, a vast plateau in the heart of peninsular Spain, has elevations that range from 610 to 760 meters. Rimmed by mountains, the Meseta Central slopes gently to the west and to the series of rivers that form some of the border with Portugal. The Sistema Central, described as the "dorsal spine" of the Meseta Central, divides the Meseta into northern and southern subregions, the former higher in elevation and smaller in area than the latter. The Sistema Central rims the capital city of Madrid with peaks that rise to 2,400 meters north of the city and to lower elevations south of it. West of Madrid, the Sistema Central shows its highest peak of almost 2,600 meters. The mountains of the Sistema Central, which continue westward into Portugal, display some glacial features; the highest of the peaks are snow-capped for most of the year. Despite their height, however, the mountain system does not create a major barrier between the northern and the southern portions of the Meseta Central because several passes permit road and railroad transportation to the northwest and the northeast.

The southern portion of the Meseta is further divided by twin mountain ranges, the Montes de Toledo running to the east and the Sierra de Guadalupe, to the west. Their peaks do not rise much higher than 1,500 meters. With many easy passes, including those that connect the Meseta with the Andalusian Plain, the Montes de Toledo and the Sierra de Guadalupe do not present an obstacle to transportation and communication. The two mountain ranges are separated from the Sistema Central to the north by the Tagus River.

The mountain regions that rim the Meseta Central and are associated with it are the Sierra Morena, the Cordillera Cantabrica, and the Sistema Iberico. Forming the southern edge of the Meseta Central, the Sierra Morena merges in the east with the southern extension of the Sistema Iberico and reaches westward along the northern edge of the Rio Guadalquivir valley to join the mountains in southern Portugal. The massif of the Sierra Morena extends northward to the Rio Guadiana, which separates it from the Sistema Central. Despite their relatively low elevations, seldom surpassing 1,300 meters, the mountains of the Sierra Morena are rugged.

The Cordillera Cantabrica, a limestone formation, runs parallel to, and close to, the northern coast near the Bay of Biscay. Its highest points are the Picos de Europa, surpassing 2,500 meters. The Cordillera Cantabrica extends 182 kilometers and abruptly drops 1,500 meters some 30 kilometers from the coast. To the west lie the hills of the northwest region.

The Sistema Iberico extends from the Cordillera Cantabrica southeastward and, close to the Mediterranean, spreads out from the Rio Ebro to the Rio Jucar. The barren, rugged slopes of this mountain range cover an area of close to 21,000 square kilometers. The mountains exceed 2,000 meters in their northern region and reach a maximum height of over 2,300 meters east of the headwaters of the Rio Duero. The extremely steep mountain slopes in this range are often cut by deep, narrow gorges.
