Every state has its fair share of eerie legends, paranormal sightings, and spooky haunts that locals know to avoid after dark. But for many ghost hunting enthusiasts, the Gem State isn't top of mind when it comes to the supernatural. Make no mistake, though  - Lewiston, Idaho has an assortment of haunted places and ghostly entities! From haunted hotels to abandoned asylums, and a few spooky cemeteries for good measure, Idaho has enough haunted spots hidden in its recesses to chill even the most stoic of skeptics.

But while every small town has a creepy old building or two, some cities have an extra dose of the supernatural. Downtown Lewiston, Idaho is definitely one of them. These days, Lewiston isn't exactly a small town, but back in the Gold Rush of the 1800s, Idaho's quiet capital had a major population boom as prospectors flocked to the area. What's more, according to the legends that still haunt many of the city's original buildings today, a number of those residents never actually left. Here's the spook-lore:

Located right on the Washington-Idaho border and at the confluence of the Snake and Clearwater Rivers, Lewiston is a bustling seaport hub with a population of around 30,000 people.

Lewiston's long, fascinating history includes much more than being a notable stop on the Lewis and Clark expedition. It also includes a stint as Idaho's original state capital and as the site of a number of political and gold uprisings during the 1800s. As a result, Lewiston is no stranger to the types of untimely happenings that result in spirits hanging around.

But for many, Lewiston's impressive supernatural activity begins with Morgan's Alley, where the presence of the infamous "Blue Lady" has been felt, witnessed, and documented by countless local residents.

While nobody is entirely sure of her identity, the Blue Lady is thought to be a local religious woman, possibly by the name of Mary Spalding, who was displeased with the goings-on at the former saloon and brothel.

Since she passed away before the gentleman's club was shut down, it is said that she now stays behind to ensure it stays that way. The Blue Lady is most often seen gracefully gliding up and down the stairs, dressed head to toe in a blue gown with her blonde hair neatly curled in the style of the time.

The Episcopal Methodist Church downtown is also a major hotspot for the paranormal.

Formerly home to the Civic Theater and the Anne Bollinger Performing Arts Center, this impressive historic building has always been an iconic sight in downtown Lewiston. But behind the scenes and before being condemned, there were hundreds of recorded sightings of mysterious aura, ghostly visitors backstage, unexplained lights, and even physical disturbances during stage productions.

Many attribute these happenings to a series of murder-disappearances that took place here, a possible body buried on-site, and the trapped souls of those who got caught up in the whirlwind of the unfortunate crimes.

With the future of the structure still to be determined, the fate of the supernatural residents is in limbo as well.

Historic and elegant, the Lewis Clark Hotel is a magnificent and vibrant wedding and event venue by day. At night, however, mysterious figures have been seen and heard roaming the halls.

The fantastic structure was built in the 1920s and has been through its fair share of turmoil over the decades. Rumors of the west ballroom being particularly active continue to circulate. Maintenance crews have noted movements just out of sight, and tell of eerie feelings that have no logical source.

But much of Lewiston's chilling past and haunted present stems from some of its most heartbreaking moments in history.

In the late 1930s, Lewiston was a major hotspot for polio, and a dedicated tuberculosis ward at the Somerville Home was opened to care for even more ill patients over the next few decades. While the hospital is now residential, the property itself continues to pulse with the presence of those who lost their lives there.

Reports of orbs and lights in the adjacent fields, as well as inexplicable energy and temperature changes in the vicinity continue to haunt the rural landscape where the original ward once stood. Only time will tell if the current residents have any new tales to add to the lore.

Of course, these locations are just a few of the many spooky spots that Lewiston is hiding. The Normal Hill Cemetery, old Carnegie Library, and many others have their own haunted legends to share.

Disembodied voices and unusual shadows are just the start of the activity that has been reported at these places.

Not to mention Lewiston's incredible (but eerie) network of underground tunnels crisscrossing beneath the city. These dark, little-known caverns are chilling in and of themselves, but the hair-raising stories that fill the walls - and indeed the ghostly stories that haunt the shops they run beneath - are unlike anywhere else in the state.

Since many of Lewiston's most haunted places are private property and can't be explored without permission, the best way to get a full dose of Idaho's most haunted town is to take a truly unnerving ghost tour.

Hosted by a local expert, Garry Bush, attendees will get to go underground, beneath the city itself, into the secret tunnels that wind beneath Main Street. You'll also delve deep into Lewiston's very real history and its tangible, haunting remnants. Every tour is different, and each excursion offers new opportunities to encounter someone (or something) otherworldly firsthand.

Whether you're a believer in the paranormal or not, Lewiston has some pretty incredible history to see and experience! But a stroll downtown or an official ghost tour under the cover of darkness might just make a believer out of you.

A number of paranormal teams have visited Lewiston's haunted hotspots to validate or debunk the many legendary claims. All signs and EMP signals point to some serious activity here, but you'll have to visit for yourself to see. Fortunately, ghosts don't just come out during spooky season - so go ahead and add a visit here to your next road trip! Or, check out Southern Idaho's most haunted town.
