Top Indiana Natural Attractions in 2026

"More Than a Tour—A Full-Scale Investigation" Why settle for a 90-minute walk-through when you can own the night? Our Indiana State Sanatorium pass gives you unprecedented access to the entire complex, including the notorious Adams Hall and the underground tunnels. Your ticket includes a bonus Day Tour pass, allowing you to photograph the haunting architecture by day before the 9-hour investigation begins at night. We provide the professional equipment and the expertise; you provide the courage to face what lingers in the halls.
