The Grotta Gigante cave is one of the largest accessible caves in Europe, offering an unforgettable experience with its stunning size and colors. There is something for everyone when it comes to exploring the cave: you can walk along the established route, sign up for adventurous caving, or enjoy a wine bar on-site. During holidays, they even host children’s shows inside the cave. The guided tour lasts about 1 hour, and in the summer, make sure to dress warmly, as the temperature inside remains at 11°C year-round.
