Which national park was recognized first, Garajonay National Park or Guadarrama National Park?
Guadarrama National Park Sierra de Guadarrama National Park (in Spanish: "Parque Nacional de la Sierra de Guadarrama") is a national park in Spain, covering nearly 34,000 hectares, the fifth largest in Spain's national parks system. The Guadarrama mountain range ("Sistema Central") contains some ecologically valuable areas, located in the Community of Madrid and Castile and León (provinces of Segovia and Ávila). The law that regulates the recently approved national park was published in the BOE in  26, 2013 (2013--) .
Saguaro National Park Saguaro National Park in southern Arizona is part of the National Park System in the United States. The park land consists of two distinct areas—the Tucson Mountain District (TMD) west of the city of Tucson and the Rincon Mountain District (RMD) east of the city—that preserve Sonoran Desert landscapes and diverse fauna and flora, including the giant saguaro cactus. The volcanic rocks on the surface of the TMD differ greatly from the surface rocks of the RMD; over the past 30 million years, crustal stretching associated with the Basin and Range displaced rocks from beneath the Tucson Mountains to form the Rincon Mountains. Uplifted, domed, and eroded, the Rincon Mountains remain significantly higher and wetter than the Tucson Mountains, and the higher elevations of the RMD support plant and animal populations that do not exist in the TMD.
