Given the considerable limestone content of the waters, its sedimentation takes place with formations of wide concreted surfaces.
In the most illuminated areas the presence of travertine is remarkable, with alternating moss and other plant residues Inside the artificial cavities, there are some section of tunnels explored by speleologists.
Given the constant temperature in the deepest parts of the caves, and the progressive decrease in light, a series of micro-environments of considerable botanical and zoological interest can be observed.
At the end of the path in the gorge, the equipped path leads us to an ancient mill (restaurant) and, following the signs on the spot, after exiting the main gorge you will arrive at the Mulinetto, a historic structure built on two floors. Open to the public for photographic exhibitions, events but also for the simple visit which, going up to the 2nd floor, offers a pleasant view of the nearby waterfall.
Going up the path that passes above the restaurant mill, proceed up towards the end of the park. Along the trail, steep at first and then flat, we meet on the right two small renovated houses, destined to become Museo dello Scalpellino (The Stonemason Museum), in memory of the ancient craft.
The route ends by exiting directly on the Provincial Road 151, almost in front of a cave (Santa Barbara’s cave), previously used as a mushroom farm and now attending to be used as an educational laboratory in the future.
In reality those that can be visited here are only a part of the existing caves; other similar “caves” are spread throughout the high part of the territory, up to Masarè above Borgo Ciser. One of these, 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 wonderful ice stalactites, are a reference point for environmental education workshops and a destination for thousands of visitors every year.
