The Colle dell'Arpione

Embed this item to access it offline

Moderately long excursion, with a long tract on a dirt road and the rest along an easy trail. The return journey includes a portion at the higher altitude.

From the ancient terraced fields, now partly reclaimed by the woods, the route continues through broad meadows on calcareous ground, in which numerous sinkholes have appeared. The return leg passes through a lovely tract of beech forest.

    Flora

    The invasive ash woods

    Invasive ash woods are woods composed mostly of common ash and mountain maple, which in recent times have settled on plots that were once cultivated and then abandoned and for this reason they are called newly formed woods. These are generally luxuriant populations because they have established themselves on fresh and deep soils; they are also unstable because they are destined to give way to oak, beech or fir woods.

    The marble quarry

    On the orographic left of the valley, the scrap and detritus dumped from the quarry can still be seen. Walking along the trail, if one observes carefully, there are blocks of marble that have fallen from the quarry above, although time and the elements have combined to coat them with a grayish film that conceals their bright white interior.

    Geology

    The sinkholes

    The basin, located on calcareous ground, due to erosive phenomena of the water, has some characteristic sinkholes in the ground, some quite large. These typical karst emergencies, originating by dissolution or collapse, convey water underground and are called sinkholes or sinkholes.


Description

From the hamlet of San Bernardo di Desertetto (1085 m) follow the paved road that crosses the town and turns into a dirt road. You ignore various side branches until, in the locality of Borghignon, the road forks: on the right the cart track (closed by a bar) leads to the old marble quarry, while on the left you head towards Colle dell'Arpione.
The dirt road rears up sharply and ends and after a stony stretch it meets a newly built track on the left, which you ignore, continuing straight on, in the shade of the trees, up to the edge of the beech forest, near a small grassy clearing. Here you ignore the dirt track to Gias del Colle dell'Arpione across the meadow and take the path to Colle dell'Arpione on the right (signs).
Heading north, with a steep traverse at times in the woods, the path reaches a large pasture valley in which there are some evident sinkholes.
Turning left, a well-trodden track among the meadows follows the bottom of the valley up to the base of the steep slope that leads to the hill. Go up the slope up to a crossroads: head right then, having reached the ridge, ignore the new track on the left for Gias del Colle dell'Arpione and, beyond a small fir grove, you come out on Colle dell' Arpione (2:10 hours from Desertetto).
To return, from the pass you return to the penultimate crossroads encountered, then take the track which, among the rhododendrons, points towards the nearby beech forest.
As soon as you enter the wood, an excellent path appears, which further on becomes an easy mule track and then a sheep track, then meets the forest track which, descending at first with moderate slopes, then more accentuated, returns to the dirt road traveled on the outward journey right at the point where it ends, and from here to Desertetto (1:30 hours from Colle dell'Arpione).

Recommandations

If you want to complete the itinerary in the height of summer, it is best to do it in the opposite direction, in order to take advantage of the coolness of the northern exposure and the presence of the beech forest during the ascent.
