Time outdoors can lower stress and quiet an overactive mind. But Mother Nature occasionally has other plans. Dark shadows, snapping twigs, lonely bridges, or a sudden unease can make even the most rational hiker glance over their shoulder.

Whether you believe in ghosts or simply appreciate local legends, these supposedly haunted natural landmarks in Missouri and Illinois may be chilling enough to make you pick up the pace before dark.

Zombie Road
Perhaps Missouri’s best-known haunted path, Zombie Road is now part of Rock Hollow Trail along the Meramec River in Wildwood, Missouri. The trail’s densely forested bluffs and abandoned railroad have inspired decades of tales about shadowy figures, phantom railway workers, mysterious disappearances, and even an escaped asylum patient.

Paranormal investigators have reported apparitions and unexplained sounds here, and the trail gained wider notoriety after appearing in the 2007 documentary Children of the Grave. While the area has a rich history tied to Native American travel routes, railroads, and a few documented accidents, there’s little hard evidence to support its supernatural claims.

Speaking of zombies, Zombie Trail is a narrow, dirt-and-rock path that branches off from Rock Hollow Trail. Hikers and mountain bikers love it for its steep climbs, tight switchbacks, scenic views — and a scarcity of the undead.

Meramec Caverns
As you descend into the chambers of Missouri’s most famous cave system, located in Stanton (just follow the hundreds of highway billboards), it’s easy to see how Meramec Caverns inspires ghost stories. Visitors and guides have reported unexplained voices, mist-like apparitions, cold spots, and an unsettling sense of being watched, especially in an area known as Ghost Alley.

Many tales center on outlaw Jesse James, who supposedly used the caves as a hideout. What is fact, however, is that Native Americans, French explorers, and miners have used the cave for centuries. In a place with so much history, the past can feel a little more…present.

Weeping Falls
Also known as Dripping Falls, this small waterfall in St. Louis County’s Creve Coeur Lake Park is closely linked to the legend that gave Creve Coeur (French for “heartbreak”) its name.

According to folklore, a Native American woman, devastated by the loss of her lover, threw herself from the nearby cliffs. Visitors have since reported hearing a woman crying, catching sight of a female apparition, and simply feeling an unexpected melancholy.

Cry Baby Hollow
Like similar legends across the country, this secluded ravine in the Missouri Ozarks, located off of Highway DD just outside of Crocker, is said to echo with the cries of a lost infant or a grieving mother. Most versions tell of a pregnant woman who died in the ravine or of a mother searching for her child during a storm.

Visitors have reported glowing lights, unexplained vehicle trouble, freezing-cold spots, and sinister red eyes in the dark. Some stories even claim the hollow is a gateway to hell. Historians dismiss the tales as urban legends, though stories about the area’s creepiness continue to circulate online.

Cave-in-Rock State Park
Situated along the Ohio River, this Southern Illinois state park combines beautiful scenery with a notorious past. In the late 1700s, the park’s cave served as a hideout for river pirates and became linked to robbery, murder, and buried treasure.

Today, visitors report whispers, footsteps, shadowy figures, and an oppressive atmosphere. Though the cave’s unusual acoustics may explain some of these experiences, its violent history continues to fuel local legends and attract visitors.

Blackwell Bridge
Just south of De Soto, Blackwell Bridge is a favorite among Missouri ghost hunters. Stories include disappearing hitchhikers, phantom vehicles, glowing lights, and shadowy figures.

One legend claims that flashing your headlights three times after dark summons a ghostly vehicle to chase you away. Another tells of a judge who carried out executions nearby, though researchers have found no supporting evidence. That said, the area’s Civil War history, abandoned structures, and old cemeteries have kept the supernatural stories alive.

The Senath Light
The Senath Light is part of the family of mysterious “spook lights” reported throughout the Ozarks and the South. This occurrence is found near the railroad tracks in the Missouri Bootheel town of Senath. Witnesses have reported seeing a glowing orb that appears along rural roads at night, changes color, approaches vehicles, and disappears when followed.

Local explanations range from a ghost carrying a lantern in search of a lost loved one to the spirit of a railroad worker who met a tragic end. In 2006, investigators from an Arkansas TV station attempted to document the phenomenon. Whatever the true cause, the light continues to puzzle visitors.

Devil’s Backbone
This jagged rock formation at Bell Smith Springs in Southern Illinois’ Shawnee National Forest feels mysterious even before the ghost stories begin. Dense forests, towering bluffs, and deep ravines have inspired reports of unexplained footsteps, strange lights, and the feeling of being watched. While there’s no documented evidence it’s haunted, the landscape is eerie enough to let your imagination take over.
