Approach
If you have a car you can go to Rodillazo (1340 m) using a narrow mountain road. If you have used a coach, or you want to walk more you can start lower, from Felmín (1091 m).
There are too much room to park your car in Rodillazo, specially on weekends, because it´s a popular route and the space to park is small.
In Felmin you´ll find enough space.
Route Description
3D Google Earth map
Basically leaving back Rodillazo, you must go up a little valley where there is a little stream. As you are getting higher on your back you´ll see a high col with Machamedio Peak on the right.
Just continue walking, you´ll see a little building on your left. You´ll need to look for a path on your right hand that goes up clearly. Take it, you´ll be at the highplane called Valle del Marqués soon.
If you have time, you can visit the Cueva de Moruquín, or just walk along the highplane. The cave is on the right of the peak. It´s not difficult to discover, the entrance it´s big enought. Just remember it´s on the foot of the Correcillas mountain, but leaving back the summit.
