Lost World Caverns, a famous underground destination in Southern West Virginia, is open throughout the year except for January and February when tours are only available on weekends. Visitors can join the self-guided tour and freely walk around a half-mile loop 120 feet below the ground for around 45 minutes. Apart from the self-guided tour, visitors who join the Wild Cave Tour, a guided tour, can explore the deepest part of the underground formation. Show more
