Donostialdea

Donostialdea is one of the eight regions of Gipuzkoa, in the Basque Autonomous Community in Spain. It corresponds to the basin of the lower Urumea River, along with a strip of basin corresponding to the Oria River. The region's name is derived from Donostia, the Basque name of San Sebastián, the capital city of Gipuzkoa. The region comprises eleven municipalities extending in an area of 305.72 km2 (see below, data released in 2006). It borders in the east with the region or subcomarca of Oarsoaldea, on the south with Leitzaldea or Norte de Aralar in Spanish (Navarre), on the west with Urola Kosta and on the north with the Bay of Biscay. The area is served by the San Sebastián Metro, part of the Euskotren Trena network operated by Euskotren.
