The interior of the Crist di Val cave is characterized by ancient rock carvings. It is reached via a very steep track following wooden posts. From the cave, there is a wonderful view of Monte Verzegnis and Casera Val.

Beautiful place to walk and take pictures of some beautiful views. It is full of tunnels and caves. Only problem in summer if the grass is a bit high there can be ticks

The visit to the cave is easily accessible, while the visit to the ravine involves the descent of 207 steps, often slippery due to the humidity which is not recommended when wearing clothing and especially MTB shoes

The Pradis Caves are a complex of karst cavities of various extensions and depths, positioned on several levels along a deep gorge dug over the millennia by the Cosa Torrent in the Upper Cretaceous limestone rock. Since those distant times these places have been in continuous evolution and transformation due to the effect of "karst", mainly due to the dissolution of the limestone rocks by rainwater but also to erosion phenomena. The Ravine of the Pradis Caves named after Don Giacomo Bianchini is an open book on geology and karst and allows you to appreciate the power of the waters of the Cosa stream. The Ravine, with its waterfalls, natural arches, caves and cavities, is a karst environment unique for its beauty. Here the force of nature and water are shown with all their power and majesty, an open-air atlas of geology that has fascinated generations of visitors, from Prehistory to the present day. source: www.grottedipradis.it

https://www.komoot.com/it-it/tour/692389420 The route follows CAI trail marker 720. Starting from the southern entrance of Rivellino Park, you cross it to the northern entrance. Crossing the park, you can already see the summit of Osoppo Hill with the flag flying on the lookout. The climb to the hill begins here, on the northern slope, and at the top of the trail, take the paved road on the left that leads to the fort. After passing the gate, on the right, there is a wide view of the Tagliamento River. On Osoppo Hill, there are many ruins worth visiting, given the strategic importance of the site since Celtic times. These include the roofless church of San Pietro, protected by a semi-cylindrical metal roof, the Savoy powder magazines, the tombs of the Savorgnans, the foundations of a Napoleonic barracks, and even the fossilized footprints of a Hipparion, the ancestor of the horse. The visit continues to the southern edge of the hill, to the Piazzale delle Cupole, where the remains of the artillery batteries are located, which can also be visited inside (a flashlight is recommended). A small path leads to the southern terrace, where the view opens up. Retracing our steps, we reach the square in front of the fort, with a small lake and the Casa del Tamburo (Drum House). On the right, there's another expansive view, this time towards Gemona. From this side of the fortress, we reach the lookout, where the Italian flag flies, the highest point on the hill, offering a 360-degree panorama. To descend from the hill, we retrace our steps and, after recrossing the gate, we leave the comfortable paved road to return to the left, taking trail 720 that descends towards the village. Once we reach the level ground, we keep right to head towards Parco delle Colonie. Here, we haven't found any sign of the trail marker, but by keeping to the south side of the soccer field and easily crossing a two-meter embankment, we reach the dirt road that leads to Colle di S. Rocco. After a right bend, on the left is the access to the steps leading up to the Colle. At a viewpoint overlooking the Tagliamento River, we also find the CAI notebook to sign our visit. Following the trail, keeping right at the first fork and then left at a second, we follow the entire crest of the Colle to the little church of San Rocco, opposite which lies the final few meters of descent. Once we reach the flat again, we keep left to return, through the village, to the starting point. 13-06-2020
