Monte Raione, Mountain summit in Monti Picentini, Italy

Monte Raione is a limestone-dolomite mountain between Campagna and Olevano sul Tusciano in the Monti Picentini regional park. With Monte Ripalta, Monte Molaro and Monte Costa Calda it forms the watershed between the Tusciano and Tenza rivers. Its slopes are covered by woods of oaks, chestnuts, Turkey oaks and yews.

The western slope holds the Grotta di San Michele Arcangelo, a natural cave containing a Byzantine religious complex of the 9th–10th centuries: five buildings called martyria, set at different heights and linked by rough stairways. The Grotta di Nardantuono, also on the western side, takes its name from the brigand Nard'Antuono, who used it as a refuge in the early 1900s.

The villages around the mountain maintain herding traditions and farm practices tied closely to the seasons and mountain life. Visitors can observe how locals use the pastures and follow paths that have connected these communities for generations.

The main path to the summit starts from the eastern side and takes about three hours to reach the top, following both marked trails and natural routes. Spring through autumn offers the best hiking conditions, when weather is more stable and paths are less overgrown.
