The Grotta Gigante is an enormous cave, first opened to the public in 1908, large enough to contain the entire basilica of Saint Peter. Because of its special characteristics and constant temperature of 12°C, it is the site of scientific experiments of world interest. The oldest speleological society in Europe runs the caves and organizes guided tours all year round. A series of routes, some of which have only been opened recently, allow visitors to admire the cave (illuminated by spotlights) from different angles. You can also visit the small museum of archeological and paleontological materials from the area. Check website for timings and details.
