I recommend leaving the road here to get to the grotto. The path is much easier to pass than the path suggested by Komoot further north.

Definitely not accessible by bike, at least not at this time of year. The path is completely overgrown, and even on foot it was barely passable. But the grotto is worth the effort!

From the table shown in the photo, due to the steep slopes and finally some steps, by bike for the last stretch of about 700/800 meters. we proceed to push, but nothing impossible.

Natural cave, inside which there is a beautiful lava stone depicting the Madonna di Castello. Every 1st May the pilgrimage under 'e Gavèt is held, guided by faith and devotion to Mamma Schiavona, protector of the Sommesi, hundreds of people participate in the solemn mass which will be held right in front of the small cave, which is positioned under the spring where the ancestors fetched water. Everything is promoted and organized by the friends of the Paranza delle Gavète in collaboration with the group of Zi Riccardo and the women of Tammorra.

Boscariello cave. Challenging, but not impossible, the gathering brought a cheerful snake of Bikers up, through trees and bushes, along the slopes of Monte Sant'Angelo, to the large cave (142 meters high, surveyed by CAI in the 1970s) The cave has an uncontaminated and primordial aspect, with a large and deep room (sixty-three meters of planimetric development and thirty-one of depth). The beautiful panorama you can enjoy ranges from Vesuvius to Capri and embraces the whole territory https://www.sciscianonotizie.it/grotta-del-boscariello-alla-ricerca-del-tesoro-del-brigante-in-centinaia-alla-passeggiata-creaviva/
