For those arriving at Calcata Vecchia and wanting to descend into the Treja Valley, I strongly advise against taking the marked path that is not on the road: it is a pedestrian descent that can only be done with a bike in hand, and not even easily. Descend following the main asphalt road.

At the foot of the hill of Monte Li Santi, a few metres from the course of the Treja, the ruins of some structures built of square blocks of tuff appear: they are the ruins of the ancient sanctuary of “Monte Li Santi – Le Rote”. Since 1985, this archaeological site has provided evidence that there was an important temple here, which was constantly visited from the 6th to the 2nd century BC and was dedicated to fertility, childbirth and married life in general. During the excavations, more than 300 painted masks, numerous terracotta heads and a surprising series of iron keys and skewers were found. The artefacts were then housed in the laboratory of the Museo Civico Archeologico-Virtuale di Narce (MAVNA) in Mazzano Romano, where they are currently on display. It was an ancient custom to create cemeteries along roads and around inhabited areas of large cities. The necropolis of Monte Li Santi in Cavone is located directly along a major road cut into the tuff, a “cava” road, from which the name “Cavone” may derive. The necropolis was probably in use since the middle of the 7th century BC, as evidenced by a pit tomb found during the first excavations at the end of the 19th century. The peak of use was between the 6th and 4th centuries BC, when numerous chamber tombs with rock facades (sculpted in tuff) were created. The tombs generally have a small antechamber and a main chamber with niches dug into the wall, which were closed with tiles after the burial of the deceased. A recent project has reopened three burial chambers with decorated entrances.

Beautiful waterfalls found on the Via Francigena between Sutri and Campagnano di Roma... it's a shame that their waters are particularly polluted.

For the landscapes and also the roads, which however, at least for the part of the Province of Rome, should be maintained a little more (asphalt at times too ruined).

Cascata di Monte Gelato, located in the Parco Regionale Valle del Treja (Treja Valley Regional Park), is a captivating natural wonder in the Lazio region of Italy. It consists of a series of small waterfalls along the Treja River. Some of these falls are natural, while others have been shaped by human intervention. The constant flow of water over layers of volcanic rock has sculpted these picturesque waterfalls for millennia

The ancient village of Calcata is hidden among the Tuscia hills, inserted in the Treja valley park. Mystical place, worth a visit.
