The Church Entrance to Cueva de la Hoyuca (site 107), so called as it can be easily accessed down the field to the south of Riaño church. A climb down just inside the entrance meets a crawl that emerges in Quadraphenia. In the 1990's, one section of passage was inundated with cow shit which, by October 2015, had completely disappeared.
