Which park in Spain is bigger Guadarrama National Park or Atlantic Islands of Galicia 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--) .
Archipelago National Park Archipelago National Park (Swedish: "Skärgårdshavets nationalpark" , Finnish: "Saaristomeren kansallispuisto" ) is a national park in Southwest Finland. It was established in 1983 and covers 500 km2 of land areas, a huge land area considering that the area mostly is outer archipelago with few islands even 1 km - and the big ones are inhabited and mostly privately owned and thus not part of the national park. The park's web pages give that number as non-qualified "area". It is part of the UNESCO biosphere reserves and received a PAN Parks certificate in 2007.
