Northwest of Seville and west of Aracena, the Parque Natural Sierra De Aracena is a relatively lush region that has numerous villages linked by a well-maintained trail system.
In the Parque Natural Sierra De Aracena, one of the more popular hikes is the figure-eight route linking the scenic villages of Alajar, Castano del Robledo and Galaroza. This is a six hour trek without stops, so if you get started early, it could be done in a day.
If you start in Alajar, the signposted route leaves the A470 from the western edge of town. On the way to El Castano del Robledo, there are several marked turns and the routes passes through a nice cork-oak forest. From El Castano, the route to Galaroza starts on the north side of town passing through Area Recreativa Capilla del Cristo.
Overall, Alajar-Galaroza is the 20th most popular hiking trail of all 21 hikes in Spain.
