The cave entrance is located inside a structural trullo, the iconic dry-stone hut with a conical roof common in the Valle d'Itria.
It was discovered in 1931 by the local speleological group Gruppo Grotte Putignano.
The cave contains a diverse collection of 'fistulous' stalactites, which are thin, straw-like formations.
The site sits along the SS 172 road, a primary artery connecting the towns of Putignano and Turi.
Karst erosion here has created a vertical development path, moving from the surface down into the chamber network.
Grotta del Trullo is the first karst cave discovered in Italy to be opened to the public for tourism, with its inaugural visit dating back to 1935. Located in the Apulian landscape, the cave system is carved into Cretaceous limestone and features a complex array of natural speleothems. Visitors descend approximately 10 meters below ground level to access the main subterranean chambers. The environment is characterized by stable temperatures and high humidity, which have contributed to the preservation of delicate stalactite and stalagmite formations. The site is situated directly beneath a traditional Apulian trullo, which serves as the unique entrance structure for the cavern. Geological studies indicate that the cave was formed through the dissolution of carbonate rocks by acidic groundwater. It serves as an accessible introduction to the extensive karst topography prevalent in the Murgia plateau. The cave is managed by local speleological groups who conduct guided tours to maintain safety and conservation standards.
The entrance area inside the trullo provides a unique contrast between the traditional architecture and the jagged subterranean opening.
Wear sneakers with good grip as the internal paths can be damp and slippery.
Bring a light jacket, as the temperature inside the cave remains consistently cool even during hot summer months.
Book your guided visit in advance during peak holiday periods to ensure availability.
Avoid arriving without checking the latest seasonal status, as the cave occasionally closes for maintenance or during off-peak winter periods.
Operations are highly seasonal; the cave is typically open for guided tours during spring and summer months and may be closed throughout the winter.
Do not touch the rock formations, as oils from human skin can permanently halt their growth and discolor the calcite.
