The abandoned Harlem Valley Psychiatric Center in Wingdale, NY, features a extensive network of underground tunnels that once connected many of its 80+ buildings, allowing for the transport of food, supplies, and patients. These tunnels, often described as dark, eerie, and prone to flooding, are a major focus for urban explorers. # fyp
