Sorry...the name is wrong: they are the Pennavaire waterfalls in Martinetto, in the hinterland of Albenga.

The Toirano Caves are a complex of karst caves located in the Savona hinterland, one of the most important speleological and archaeological sites in Italy. The tourist route winds primarily through two connected caves: the Bàsura Cave and the Santa Lucia Superiore Cave. The Bàsura Cave, also known as the "Witches' Cave," is famous for its prehistoric finds. Neanderthal footprints and a vast "cemetery" of cave bears, who hibernated there, have been discovered here. The Santa Lucia Superiore Cave captivates visitors with its geological beauty, rich in stalactites, stalagmites, columns, and other rock formations. The Toirano Caves thus offer a fascinating journey through time, combining the wonder of underground nature with evidence of prehistoric life.

Panoramic point on the whole coast and the hinterland. Too bad for the complete lack of springs in the area…

Very beautiful view, both on the sea and towards the mountains. Reachable by a path with ups and downs from the Sanctuary, or with uphill paths from Toirano or Borghetto
