Starting place: the sawmill in Opi.
Starting place is a disused sawmill at 1087 meters a.s.l. in the territory of Opi, where a small path after 300 mt crosses the Fondillo stream on a small bridge, in an area called Grotta Fondillo.

From this point onwards, the track follows this clear-water stream. The relaxing walk is typical for the special environment created by the stream; here and there the branches of the trees create natural bridges, small waterfalls refresh the wanderer, and there are occasional pools.
The track leads to Valle Cacciagrande, and in a small meadow there is a closed refuge, with a fountain nearby with drinkable water. After this meadow, you get into the shadows and lights of small forest of larch and fir trees beech wood, to enter finally the beech forest. Gently you climb up to a turning point where a red/orange mark shows the way to the spring of the Fondillo, in a place called "Grotta della Fate" a few minutes away, full of green, light and water, with flourishing hygrophile vegetation.

Following the main track through the deep wood, where you often meet century-old beeches, you reach finally a steep mule path and after about 30 minutes you arrive at the wide valley called Valico dell'Orso, your destination: the landscape is astounding, you can see the whole val Fondillo, monte Amaro, monte Capraro, Forca Resuni, monte Petroso and the upper Valle di Canneto. From this observation point another itinerary leads over the mountain pass and to Civitella Alfedena. But you can leave that to another occasion and return down the same way you came, just one and a half hour of easy, downhill walking.
