Inside the limestone of the Alburni

At the foot of the Alburni Mountains, the Grotte di Castelcivita open into a network of limestone passages and chambers. The guided route passes beneath stalactites and between columns, with narrow sections giving way to larger caverns.

The entrance lies beside the Calore valley, at the south-western foot of the mountains. The mapped cave system extends for about 4.8 kilometres, although a standard visit covers only part of it. Water has dissolved passages through the limestone; mineral deposits have subsequently built up the formations seen along the route.

Lighting picks out the folds, ridges and overhangs along the route. In the larger chambers, pause to look upwards: some of the most intricate formations hang well above the walkway.

What to look for underground

Stalactites hang from the ceiling, while stalagmites grow upwards from the floor. Where the two join, they form columns. Elsewhere, thin mineral curtains follow the edges of sloping rock.

The official route description includes the Sala del Castello, the Sala del Trono and the Sala dei Salami: names prompted by the shapes of their formations. The pathways also reveal changes between narrow passages and much larger spaces.

There is human history here too. Archaeological deposits identified at the entrance in 1972 contained stone tools and fossil remains. The caves’ official account dates human use of the site to around 40,000 years ago.

Choose the right cave visit

The standard guided tourist route takes about an hour. For most visitors, this is the straightforward introduction to the caves and leaves time for the surrounding landscape.

The operator also offers a visit by helmet light and a longer amateur caving route. The latter takes about four hours, continues beyond the tourist section and requires advance booking. It is a different commitment from the ordinary visit: confirm the terrain, age requirements and availability directly with the operator.

Wear shoes with grip and bring a light layer. Anyone concerned about steps, uneven surfaces or restricted passages should discuss the chosen route before travelling. Download the English audio guide in advance if needed; the operator advises that Wi-Fi is unavailable inside.

Check current departures and booking arrangements before travelling, particularly for winter openings and specialist visits.

Back outside: the Alburni landscape

The pale cliffs and wooded slopes outside help put the underground visit in context. This is the mountainous northern part of the Cilento, Vallo di Diano and Alburni National Park, with settlements clustered around the lower slopes.

Postiglione is another village to consider while exploring the Alburni. Its compact centre gathers around the castle, with gardens and newer houses extending outwards. A stop here combines well with the caves if you have time to explore the area above ground.
