SI O05

This medium-length stage, with predominantly descending elevation, departs from the Monti Ernici to descend to Filettino, the highest municipality in Lazio, located at the meeting point with the Monti Simbruini. The entire itinerary is supported by excellent horizontal and vertical signage. From Campocatino at 1792 m, exactly from the CAI Frosinone Refuge "Mario Calderari," a stopping point of SICAI Lazio, it takes only a few minutes to reach the spacious square of the tourist area. From the signage table located on the left edge of the wide square, you descend and cross the plain of Campo Catino, heading towards Vado Piano at 1798 m. The route to follow will be number 610. In this first part of the brief path, you will have a broad view of the karst phenomena present in the large plain of Campo Catino. From Vado Piano, the trail descends steeply northward into the Fosso della Brecciara and, after briefly following a winding path through the dense beech forest, a steep scree leads near the locality of Passo del Diavolo, from which you descend to the Pratiglio di Sant'Onofrio. From the route marker, the trail, always adequately marked, makes a sharp left turn heading west. Leaving the Pratiglio di Sant'Onofrio, the path continues at a mid-slope level in the forest, now also characterized by oaks and frequent junipers, encountering two springs, both in a state of abandonment. After a flat section, you reach the slightly defined ridge of Serra Magliano and shortly thereafter the Sella di S. Onofrio at 1408 m. From here, the trail follows another sharp deviation to the right, now heading east, and through a dense beech forest it begins to descend towards the Valle della Fontana. Rest area at 1215 m. Upon reaching a new sign on well-marked terrain, the trail undergoes another change of direction, now heading north towards Filettino, following a path that is always well-marked and visible, at the foot of the area known as "Scagnaro dello zoppo." Approaching the village, you will have the opportunity to observe various dry stone structures built to contain large clearings used for seasonal cultivation and especially for charcoal production, which was common until the early 1970s. Upon reaching Filettino, accommodation can be found.
