Travelers seeking a unique blend of history, adventure, and a touch of relaxation will find this WW2 & Underground Discovery Tour in Lazio, Italy an intriguing option. Priced at just $35 per person, this experience promises to take you beneath the surface of Rijeka’s untold past—though it’s worth noting, the tour actually takes place in Croatia, near Rijeka, not Italy—into the shadowy corridors of an abandoned fortress. With private tours available upon request and a focus on uncovering the unknown, this adventure is designed to appeal to those who love history mixed with a bit of mystery and thrill.
What sets this tour apart are a few standout elements. First, the access to the underground San Giovanni fortress, usually closed to the public, offers a rare peek into wartime military construction.
