The itinerary follows the historical route for the ascent of Mount Vesuvius from the town of San Sebastiano to the foot of the hill on which the Vesuvius Observatory is. The trail, also suitable as bridle path, runs along part of the track of the cogwheel train that connected the Power Station (today known as the Cook Station, owned by the Park Authority and recently renovated) to the Observatory.

The rack section (railway traction system used in cases of considerable slopes) was part of a wider railway line that since 1903 transported tourists from Pugliano (Herculaneum) to the funicular lower station. The eruption of 1944 irreparably destroyed the funicular, which in 1953 was replaced by a chairlift that was then closed in 1984 because it was often unusable due to the wind.

However, the railway was about to be closed anyway and in 1955, with the completion of the road that climbs up to a thousand metres from Herculaneum, the train ran for its last time.

The first part of the trail proceeds slightly uphill along a paved road, lined with rows of pines, which crosses cultivated land. Go along the last part of the spectacular lava flow of 1944, which appears for most of the year as a grey expanse due to the presence of the Stereocaulon vesuvianum, but in late spring it turns into a colour explosion, thanks to the flowering of the broom and red valerian.

The birds are typical of the rural areas and the Maquis shrubland: the serin, the long-beaked black bunting, the red-backed shrike, which from the perch scrutinizes the countryside looking for preys, the Sardinian warbler, which builds its own nest among brambles and bushes; at dusk the diurnal birds finish their activities to make room for the rulers of the darkness, so the nocturnal hunting of the barn owl, the owl and the Eurasian scops owl begins.

At the end of the asphalted road, a fumarole located between the blocks of lava allows you to feel the heat of the volcano, at only 450 metres above sea level. Then a dirt path uphill begins and after passing a bar you dive into a shady environment, dominated by a mixed forest with a rich undergrowth, which is characterized, among other species, by the butcher's broom and the red lily; the most widespread arboreal species are the locust tree and the chestnut tree. After a few hundred metres from the bar there is the close destination, where you can identify the ancient route of the cogwheel train. Along the way, various naturalistic engineering works are visible; by going up, you reach a viewing point on the Gulf of Naples that represents the intermediate destination.

The path proceeds to a widening, where the vegetation is enriched by the presence of the elder and the hawthorn, among the foliage you can see a well of Bourbon age for the collection of rainwater. The itinerary continues up to the provincial road, however a detour is recommended along path n. 9, through the left lane, which in a short time leads to the lava flow of 1944, from which you can enjoy a breath-taking view.

The route of the journey is then resumed proceeding in the opposite direction up to the entrance where the destination is placed.
