Title: Spain
Content:   Mainland Spain is a mountainous country, dominated by high plateaus and mountain chains. After the Pyrenees, the main mountain ranges are the Cordillera Cantábrica (Cantabrian Range), Sistema Ibérico (Iberian System), Sistema Central (Central System), Montes de Toledo, Sierra Morena and the Sistema Bético (Baetic System) whose highest peak, the 3478 m Mulhacén, located in Sierra Nevada, is the highest elevation in the Iberian Peninsula. The highest point in Spain is the Teide, a 3718 m active volcano in the Canary Islands. The Meseta Central (often translated as "Inner Plateau") is a vast plateau in the heart of peninsular Spain. There are several major rivers in Spain such as the Tagus (Tajo), Ebro, Guadiana, Douro (Duero), Guadalquivir, Júcar, Segura, Turia and Minho (Miño). Alluvial plains are found along the coast, the largest of which is that of the Guadalquivir in Andalusia.
Title: Cantabrian Mountains
Content:   The Cantabrian Mountains or Cantabrian Range (Cordillera Cantábrica) are one of the main systems of mountain ranges in Spain. They stretch for over 300 km (180 miles) across northern Spain, from the western limit of the Pyrenees to the Galician Massif in Galicia, along the coast of the Cantabrian Sea. Their easternmost end meets the Sistema Ibérico. These mountains are a distinct physiographic province of the larger Alpine System physiographic division. The Cantabrian Mountains offer a wide range of trails for hiking, as well as many challenging climbing routes. Skiing is possible in the ski resorts of Alto Campoo, Valgrande-Pajares, Fuentes de Invierno, San Isidro, Leitariegos and Manzaneda.
Title: Geography of Spain
Content:  To the west lie the hills of the northwest region and to the east the Basque mountains that link them to the Pyrenees. The Sistema Ibérico extends from the Cordillera Cantábrica southeastward and, close to the Mediterranean, spreads out from the Río Ebro to the Río Júcar. The barren, rugged slopes of this mountain range cover an area of close to 21,000 square kilometers. The mountains exceed 2,000 m in their northern region and reach a maximum height of over 2,300 m east of the headwaters of the Rio Duero. The extremely steep mountain slopes in this range are often cut by deep, narrow gorges.
Title: Tourism in Spain
Content:   Spain is a generally mountainous country, with well-known ski resorts located in several parts of the country, including the Pyrenees, the Sistema Central, the Sistema Ibérico and Sierra Nevada. For the most part, the main crest forms a massive divider between France and Spain, with the tiny country of Andorra sandwiched in between. The Crown of Aragon and the Kingdom of Navarre have historically extended on both sides of the mountain range, with small northern portions now in France and much larger southern parts now in Spain. Sierra Nevada in Spain is a popular tourist destination, as its high peaks make skiing possible in one of Europe's most southerly ski resorts, in an area along the Mediterranean Sea predominantly known for its

Title: Geography of Spain
Content:  The remaining regions of Spain are the Balearic and the Canary Islands, the former located in the Mediterranean Sea and the latter in the Atlantic Ocean. The Balearic Islands, encompassing a total area of 5,000 square kilometers, lie 80 kilometers off Spain's central eastern coast. The mountains that rise up above the Mediterranean Sea to form these islands are an extension of the Sistema Penibetico. The archipelago's highest points, which reach 1,400 meters, are in northwestern Mallorca, close to the coast. The central portion of Mallorca is a plain, bounded on the east and the southeast by broken hills. The Canary Islands, ninety kilometers off the west coast of Africa, are of volcanic origin. The large central islands, Tenerife and Gran Canaria, have the highest peaks. Pico de Las Nieves, on Gran Canaria, rises to 1,949 meters, and the Teide, on Tenerife, to 3,718 meters. Teide, a dormant volcano, is the highest peak of Spain and the third largest volcano in the world from its base.

The massif of the Sierra Morena extends northward to the Río Guadiana, which separates it from the Sistema Central. Despite their relatively low elevations, seldom surpassing 1,300 m, the mountains of the Sierra Morena are rugged at their southern edge. The Cordillera Cantábrica, 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 m. The Cordillera Cantábrica extends 182 km and abruptly drops 1,500 m some 30 km from the

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 by the Tagus River. The mountain regions that rim the Meseta Central and are associated with it are the Sierra Morena, the Cordillera Cantábrica, and the Sistema Ibérico. Forming the southern edge of the Meseta Central, the Sierra Morena merges in the east with the southern extension of the Sistema Iberico 
Title: Monte Perdido
Content:  Monte Perdido (in Spanish; Mont Perdu in French; Mont Perdito in Aragonese; Mont Perdut in Catalan, all four meaning lost mountain) is the third highest mountain in the Pyrenees. The summit of Monte Perdido (3355 m), located in Spain, lies hidden from France by the seemingly impenetrable peaks of the Cirques of Gavarnie and Estaubé. It stands in the north of Huesca province. The mountain forms part of the Monte Perdido Range and is located in the Ordesa y Monte Perdido National Park, in the western part of the Pyrenees, in the community of Aragon, Spain. Access to the mountain is easier from Spain than from France. The route starts
