Wherever you choose to go in Spain, you are certain to find no end of excellent hiking opportunities. You’ll likely arrive in either Madrid or Barcelona, depending on your final destination. From Madrid, Asturias is easily reachable by bus, train or rental car. From Barcelona, Catalonia is an easy car or bus-ride away as well.  

Outside of the three listed above, you could head to Spain’s Celt-influenced northwest and hike along the Galician seashore. The slightly wetter, but equally beautiful autonomous community is also home to la Catedral de Santiago, in Santiago de Compostela. This iconic landmark is the ending point of El Camino, a massive hike stretching from the French Pyrenees all the way to this northwestern city.
