Northeast of Seville and west of El Pedroso, the 12km Sendoro del Arroyo del las Canas rolls across flatlands and boulders that are known for their Spring wildflowers.
To reach the trailhead from Cazalla de la Sierra, head south on A432 for 16km to El Pedroso. The trailhead is on the west side of town across from Bar Triana.
The trail starts in El Pedroso. Pass an oil mill on our right hand side and enter a dehesa landscape where we will see the remains of some old granite quarries and a large granite boulder called a "bolo". There are also some very complex berrocales (groups of bolos). Reach the Arroyo de las Cañas stream and follow its course, taking in the oleander, elm, alder and ash trees. When we cross the stream we see cows, sheep, horses and pigs grazing in the dehesa area which opens out before us. Continuing through this zone of particular interest for its unique vegetation, we pass some farmhouses and come to a stone cross which shows us the way to the Ermita de la Virgen del Espino, a small Mudejar church displaying typical highland architecture. Passing the Ermita, we go through a eucalyptus forest and follow the trail back to the point of departure.
While in the Parque Natural Sierra Norte, you may also want to check out the short hike up to the old Islamic fort above the western side of the town of Constantina, or try hiking the 7km Sendero Los Castanares starting from the north side of Constantina at the north end o Paseo de la Alameda.
Overall, Sendoro del Arroyo del las Canas is the 1st most popular hiking trail of all 21 hikes in Spain.
