The path from Grotta Fai is quite difficult, and steep in places. But it's worth seeing.

Suggestive corner of meditation and prayer, which suddenly appears in the middle of the dense and silent forest, along the steep hiking path that leads to Mount Pizzoc, under the Agnelezza ('of the lambs') meadows: a small natural cave, a figurine of the Madonna and an altar. The first Madonnina was placed in 1963; the current one in 1973. In the early 1990s the site was refurbished and equipped with the small altar: since then two masses have been celebrated a year, always at 10.30am; at the opening of the hiking season (the last Sunday in April) and at its closing (the last Sunday in October). https://www.lazione.it/Vittoriese/FREGONA-messa-all-Agnelezza-per-l-interno-delle-attivita-escursioniche
