The Grotte del Caglieron are located in Breda, a hamlet in Fregona, Treviso.

The complex consists of a series of cavities, part of which are of artificial origin and part of natural origin; for the natural part, it is a deep gorge incised by the Caglieron stream on alternating layers of calcareous conglomerate, sandstone and marl of the Middle Miocene (from 16 to 10 million years ago).

There are numerous waterfalls, of several meters high, with large potholes at the base.
In the deepest part of the gorge, are noticed on the walls large calcareous concretions, which close for a tract and a part of the vault, giving to the whole the appearance of a cave.
On the walls of the gorge there are large artificial cavities, obtained from the extraction of the sandstone, the typical “piera dolza” (sweet/tender stone).

The extraction activity, which dates back to 1500 and even earlier, gave the material for the construction of jambs, lintels, etc., which can still be observed on the old houses and palaces of Vittorio Veneto and surroundings.
Interesting the extraction method practiced: being the inclined layers even over 45 °, the detachment of the material, caused by using big chisels that left signs still visible, it happened in blocks, with the warning, however, to leave columns tilted to support the vault.
The result is an evocative set of artificial cavities, distributed along the ravine, on whose bottom flows whirling and noisy the torrent, so to bring to the construction of an equipped path.

Grotte del Caglieron

Currently the complex of the Caves is interested by the making of the Grotte del Caglieron Park, largely completed. The beginning of the route, about 1 km long, is located in via Ronzon, shortly after the building of the Visitor Center; through a pedestrian boardwalk that crosses the Caglieron stream, you descend on a wide path , passing under the bridge of the Provincial road.
Along the itinerary there are numerous descriptive panels and, on the right, there is a large cavern ( Grotta dei Breda ), characterized by sloping columns that support the layers of sandstone forming the ceiling. A little further on, on the left, a wooden walkway leads to the cave used to aging the cave cheese (Grotta di San Lucio) of the Agricansiglio dairy.

Grotte del Caglieron

Returning on your steps, you will meet a belvedere in the shape of a bow, from which you can admire the splendid natural gorge and, continuing , follow it on walkways to suspended tracts.
Given the considerable content in the limestone of the waters, you has its sedimentation with formations of wide concretions surfaces, stalactites and stalagmites, of the most various shapes and colors.
In the most illuminated areas is notable the presence of travertine , with alternation of mosses and other plant residues. Inside the artificial cavities, there are some stretches of tunnels explored by speleologists.

Given the constancy of temperature in the deepest parts of the caves, and the progressive decrease in light, can be observed a series of micro-environments of considerable interest botanical and zoological.

At the end of the trail in the gorge, the equipped path brings to an old mill (now a restaurant) and, following the signs on the spot, one proceeds going back toward the terminal part of the park.

Along the trail, first steep then flat, we meet on the right two small renovated houses, destined to become Museo dello Scalpellino (The Stonemason Museum), at memory of the ancient crafts.

The itinerary ends exiting directly on the Provincial Road 151, almost in front of a grotto (Santa Barbara’s cave), previously used for mushrooms growing and now in arrangement for future use as teaching laboratory.
In reality those that can be visited here are only a part of the existing cavities; other similar caves are spread throughout the high part of the territory, up to the Masarè above Ciser hamlet. One of those, after passing the bridge over the provincial road, was dedicated from the inhabitants at the devotion of the Madonna.

The Caglieron Caves, appreciated both in summer for the coolness and in winter for the splendid waterfalls of ice, are a reference point for laboratories of environmental education and destination every year of thousand o visitors.
