Rio Martino is a semi-touristic cave recommended for visits in summer.
The lower branch can be visited without any particular difficulty thanks to a work of safety of the "Lower Branch" with walkways that facilitate the visit, even to less experienced visitors. However, we recommend suitable clothing (humidity 100% - temperature 5.5°C), waterproof footwear and flashlights. Spectacular the Great Hall of the waterfall called "Pissai" 40 m high. Access to the upper branch is reserved for specialists.
