This popular tourist spot in South Dakota is on the “Most Haunted” list.

America’s national parks are a real treat, but depending on where you’re enjoying the outdoors at one of the 429 scenic spots across the country, there might be a few tricks thrown in there, too, even if it’s not Halloween.

Traveling has gone over all the reported paranormal encounters at some of the most popular destinations in the National Park system, chronicling everything from visits by dead presidents and stories of mysterious falling objects to the unexplained disappearance of boaters and hikers.

One of South Dakota’s two national parks made the scary list.

According to The Travel, Badlands National Park is the third most haunted park in America.

They claim the area, which Native Americans called “bad country,” is full of ghost sightings and strange noises.

“Towering structures like Dog Watch Butte have a particularly bad reputation, with hikers reporting ghostly sightings and blood-curdling screams along the trails. Native Americans believed that their ancestors still lived in the area, protecting the land from all who dared enter, including their own descendants.

Along with Dog Watch Butte, the site also lists Stronghold Table as the site of numerous paranormal encounters. The area is located near the Cuny and Galigo Tables. It was the site of the last known Ghost Dance. There are no roads to the site and it is only accessible on foot.
