Especially at the beginning of the hike, there are always steep uphill and downhill sections and there are many stone steps to overcome. At least here I would classify the route as moderately difficult.

When the path enters the Barranc de la Ronyosa, a passage opens between the Mola del Ferri to the north and the Mola de Magraner to the south, narrowing noticeably. The high walls and the balsams that we are seeing make it very attractive. It goes without saying that in case of heavy rains some problem may arise to go around it.

This abandoned and dilapidated Mas would not be different from many others that are in the same conditions but, its location and the open space where the era is located, allows you to have fantastic panoramic views. It's worth stopping and enjoying the view or grabbing a bite.

Fountain magnificently arranged inside the dry stone wall of a bank. Also watch out for a trough outside.
