The Grotte di Pertosa-Auletta, nestled in the Campania Apennines near Salerno, are among the most remarkable cave systems in southern Italy. Carved by the Tanagro river over millions of years, they feature an underground lake navigable by boat — a rare experience in Italian speleotourism — alongside dramatic stalactite and stalagmite formations and traces of Bronze Age pile dwellings discovered inside.
This third and final episode follows an Italian-Malayali traveller through the concluding sections of the cave tour. Viewers can expect close-up footage of the deepest chambers, the river passage, and the atmospheric lighting that reveals the cave's geological layers — a fitting end to a personal journey through one of Campania's lesser-known natural wonders.
