This region offers a wealth of varied walking routes from your base in the northern half of the Sierra in the tiny village of Hoyos del Espino, nestled on the edge of the Gredos Regional Park and against a breathtaking backdrop of jagged granite peaks. Choose from gentle meadow strolls through the flower-filled river valleys, or comfortable higher level hikes (the park is at 1800m), where you're likely to meet wild goats and spot huge griffon vultures soaring overhead. In order for you to really get to know the entire region, we have included detailed route notes for optional day walks in the southern half of the Sierra; a contrasting cluster of tiny Mediterranean-like villages tucked away among terraces of olives, figs and vines. The beautiful historic cities of Avila, Toledo and Salamanca are also easy day trips.
