The paranormal community often associates eerie phenomena with the United States National Park Services. While many outdoor horror tales focus on Bigfoot, UFO sightings, or mysterious disappearances, traditional ghost stories rarely capture the spotlight. Yet, it would be a mistake to assume these natural wonders are free from spectral activity—assuming, of course, one believes in such things.
Below is a compilation of ten paranormal accounts involving classic ghostly encounters within the U.S. National Park system. While some tales involve ghost-related phenomena like poltergeists or time distortions, these stories highlight inexplicable events that can only be attributed to spirits lingering beyond the grave.
10. Diana of the Dunes
Located at the southern tip of Lake Michigan, the Indiana Dunes became a U.S. National Park in 1966. However, visitors have been drawn to the area's natural splendor since the 1910s. Among them was Alice Mabel Gray, a woman so disillusioned with her life in Chicago that she fled to the Indiana wilderness to live off the land. Legend has it that she loved her new home so deeply that she chose to remain there even after death.
Known as “Diana of the Dunes,” the spirit of Alice Gray is famous for swimming nude in Lake Michigan. Her ghost is also seen in several derelict houses where she once lived. One such house became a crime scene when a body was found nearby in 1922. Some connect this murder to Paul Wilson, Gray’s unofficial husband, whose off-the-grid lifestyle might have been a way to evade law enforcement.
9. The Grouse Lake Ghost at Yosemite
Yosemite National Park, established in 1890 as the third national park in the U.S., is renowned for its Bigfoot encounters and UFO reports. However, it also harbors a classic ghost story. Visitors claim to see and hear the ghost of a weeping young boy at Grouse Lake, with sightings dating back to the park’s founding.
As early as 1910, Park Ranger Galen Clark reported hearing eerie cries near Grouse Lake. He consulted members of the Ahwahneechee tribe, who shared the sorrowful story of a Native American child who drowned there. Yosemite also features another haunted site: the Yosemite Valley Pioneer’s Cemetery, where Galen Clark’s own ghost has been sighted.
8. The Haunted Volcano House
Our next haunted destination lies far to the west, in the Hawaiian Islands. Hawai’i Volcanoes National Park was established in 1916, but this story revolves around a structure built fifty years prior. The Volcano House, constructed in the early 19th century, stood within what is now the national park. After a fire destroyed the original building in 1940, a new hotel was erected on the same site.
Like many haunted locations, the new construction appears to have awakened the spirit of an elderly woman dressed in 1800s clothing. She is often seen wandering the halls and appearing in various rooms. Paranormal investigators have also reported sightings of a ghostly dog, with some suggesting it could be a manifestation of Pele, the Hawaiian goddess of fire.
7. The Horse Ghost of Big Bend
Big Bend National Park, located in the remote reaches of Texas along the Rio Grande, is one of the most isolated places in the continental United States. Known for its paranormal activity, including UFO sightings and chupacabra encounters, Big Bend’s most eerie legend involves the ghost of a mysterious white horse.
Legend has it that the horse was branded with the word “Murder” by a cowboy, possibly as a prank, and may have died during the branding. Hikers in Big Bend occasionally report seeing a spectral horse materialize out of nowhere, bearing the chilling word “Murder” on its side—a sight guaranteed to terrify anyone unlucky enough to witness it.
6. Charlie Watt at Isle Royale
Isle Royale, a Michigan island National Park established in 1940, lies in the northwestern part of Lake Superior. For thousands of years, people have inhabited the island. During winter, the waters between the island and Ontario, Canada, often freeze, creating a natural pathway for crossing.
The ghost story of Charlie Watt, however, is relatively modern. In 1845, the copper prospector and his wife, Angelique, sought fortune on the island. Dependent on supply ships for food, they were stranded during a harsh winter when no shipments arrived. Starvation eventually claimed their lives, and visitors to Isle Royale have since reported sightings of a lone prospector’s ghost wandering the wilderness.
5. Stephen Bishop at Mammoth Cave
Mammoth Cave, located northeast of Bowling Green, Kentucky, became a National Park in 1941. With over 400 miles (644 kilometers) of mapped tunnels, it is the world’s largest known cave system, with many areas still unexplored. Before its park designation, the cave was a tourist site owned by Dr. John Croghan, who utilized enslaved labor to conduct tours.
One notable tour guide was Stephen Bishop, an enslaved man who became the primary explorer of Mammoth Cave, uncovering much of its vast structure. The details of his death remain unknown, but modern adventurers have reported encountering his ghost in the cave’s dark depths. Some even claim to witness the apparitions of an entire Black family in the chamber that once served as a Methodist Church.
4. A Haunting at the Dry Tortugas
While many entries on this list focus on expansive natural landscapes, some buildings earn National Park status due to their historical significance. This is true for the forts in Key West and the nearby coral reef. Fort Jefferson, built by the U.S. government in 1825, was designed to protect against Caribbean piracy.
However, the fort’s ghostly visitors aren’t limited to pirates. Some report hearing the cries of prisoners who succumbed to yellow fever, while others claim to see the spirit of Samuel Mudd, a conspirator in John Wilkes Booth’s assassination plot, who died at Fort Jefferson.
3. The Battle of Gettysburg
The spectral reenactment of the Battle of Gettysburg is not only the most famous haunting in a National Park but possibly the most renowned in the entire United States. This pivotal Civil War clash occurred in the summer of 1863, claiming over 7,000 lives from both sides. The Union’s victory at Gettysburg marked a turning point in the war, and the battlefield was designated a National Historic Place in 1895, later becoming a National Park.
The battlefield is teeming with paranormal activity. Visitors often hear the echoes of gunfire and galloping horses. Phantom soldiers appear in photographs, and electronic devices malfunction near a rocky area called the Devil’s Den. According to local guides and park staff, the most haunted spot is a large, unnamed maple tree where six Union soldiers leaned and died within moments of each other.
2. The Wailing Woman of the Grand Canyon
The Grand Canyon, the second most-visited National Park in the U.S., narrowly trailing the Great Smoky Mountains, was championed by President Theodore Roosevelt in 1909 but didn’t become a national park until 1918. Among its many legends, the tale of a weeping woman is one of the most well-known.
Legend has it that in the 1800s, a father and son fell to their deaths during a sudden storm near what is now the Transept Trail. The grieving wife, unable to bear the loss, took her own life. She is said to appear as a ghostly figure in a white dress, blue scarf, and floral necklace, matching descriptions of an apparition seen on the trail. Her mournful cries are often heard by hikers venturing alone.
1. Edgar Watson at the Everglades
While the Dry Tortugas may not be Florida’s most renowned National Park, its ghost stories are overshadowed by the eerie tales of the Everglades. Edgar Watson, a plantation owner and serial killer, was shot and killed by residents of Chokoloskee in 1910. Watson was infamous for murdering his servants, many of whom were Black, and killing anyone who dared trespass on his land.
Rabbit Key, the Everglades island where Watson met his end, is said to be his eternal resting place, according to some accounts. A nearby museum also experiences unexplained poltergeist activity, such as motion sensors triggering unexpectedly and shadowy figures moving through the preserved general store after dark. The Everglades became a National Park in 1947 and was later designated a UNESCO World Heritage Site in 1979.
