Known as the Mother Road, Route 66 stretches across eight states, connecting Chicago to Santa Monica. Its California section is particularly rich in roadside history, vintage attractions, forgotten settlements, and stories of the Old West.
According to SIXT’s research, the highway generates thousands of searches related to ghostly encounters along its Golden State stretch.

Stories of ghostly hitchhikers and deserted ghost towns add to the road’s eerie reputation. This makes it an intriguing destination for travelers who enjoy a little paranormal mystery alongside their road-trip nostalgia.
