The excursion hereby proposed is extremely interesting under several points of view. Firstly, the itinerary gives the opportunity for in-depth, high-profile didactical studies, especially regarding the botanical and geological aspects of the territory. Concerning the vegetational aspects, this route has become a downright natural laboratory, used by the schools of Arrone also because it is supplied with some identification charts of the main botanical species present in the area. The trail is dedicated to the late lamented secretary of the Ternan section of the Italian Alpine Club, Luciano Porrazzini, prematurely deceased. In some parts of the trail it is very particularly relevant to note the presence of some small fossil outcrops of marine origin, a tangible testimonies of the deep tectonic turmoil that involved the whole area in remote times. The whole Polino region is, furthermore, particularly rich with fossil finds, especially ammonites. Another relevant feature of this route is the presence, during the spring, of a beautiful efflorescence along the slopes of Mount La Pelosa, the highest peak of the area, which makes it possible to enjoy rare specimens of flowers, including gentians, mountain tulips, wild peonies and many others. Last but not least, the landscape value of this route is relevant, as in fact it allows, during clear days, to easily admire the highest and most majestic peaks of the central Apennines, from the Sibillini Mountains to the Laga, the Gran Sasso and the Velino-Sirente massif.
