Best Ghost Towns in Idaho to Visit on Your Next Road Trip

Looking to add a dash of adventure—and maybe a few chills—to your next Idaho road trip? Make a detour to explore some of the best ghost towns in Idaho. These abandoned towns, once booming mining hubs, now stand frozen in time with weathered buildings, crumbling saloons, and echoes of the Wild West era.

While Idaho may be famous for potatoes, locals know there’s far more to the Gem State. Scattered across its rugged mountains and hidden valleys are dozens of ghost towns, each with its own fascinating story. From gold rush settlements to silver mining camps, these towns sprang up seemingly overnight and just as quickly vanished when the mines ran dry.

Idaho’s history is deeply tied to mining. The discovery of gold in Pierce in 1860 kicked off a rush of prospectors, leading to the rise—and eventual fall—of towns like Idaho City, Bonanza, and Custer. Later, silver strikes in northern Idaho’s Coeur d’Alene region made the area one of the richest mineral-producing zones in the world.

Today, these ghost towns offer a rare glimpse into Idaho’s rough-and-tumble past. Whether you’re chasing history, photographing eerie abandoned sites, or just love quirky attractions, these destinations are well worth adding to your travel plans.

Here are the best ghost towns in Idaho to visit on your next road trip—perfect for anyone eager to explore the remnants of the Old West.

Best Ghost Towns in Idaho

Custer Ghost Town

Like many ghost towns in Idaho, Custer was founded by gold miners chasing their fortune. Established in 1879, Custer quickly grew into a bustling community, peaking at around 600 residents by 1896. But as with most mining towns, the boom didn’t last long.

When gold became scarce, the town’s population dwindled. By 1910, Custer was completely abandoned, leaving behind the remnants of its short but lively history.

Custer was always a modest settlement—essentially a single street stretching for about half a mile. In its heyday, it featured two mines, a mill, a union hall, hotel, schoolhouse, several saloons, a jail, a post office, and even a small “Chinatown” area.

Custer was saved from total decay when it was placed on the National Register of Historic Places in 1981. Thanks to preservation efforts, several original buildings—like the schoolhouse, Empire Saloon, and private cabins—have been restored.

During the summer, volunteers from the Friends of Custer Museum are on hand to share stories and answer questions, making it one of the most interactive ghost town experiences in Idaho.

Nearby is Bonanza, Custer’s sister city and another ghost town worth a quick stop. Bonanza was once larger than Custer, but devastating fires in 1889 destroyed much of the town. Many residents relocated to Custer afterward. Today, Bonanza has few standing buildings left, so there’s not much to see except for the fascinating Yankee Fork Gold Dredge, which offers guided tours during summer months.

Bayhorse Ghost Town

Tucked deep within a rugged canyon in central Idaho, Bayhorse is one of the most captivating ghost towns in the state—both for its Wild West atmosphere and its stunning scenery.

Bayhorse got its start as a gold mining camp around 1864 after a few promising gold veins were discovered in the area. However, it wasn’t until 1877—when miners struck a rich lead-silver vein at the Ramshorn Mine—that the town truly began to thrive.

By 1878, a rush to Bayhorse was underway. At its peak in the early 1880s, the town was home to around 300 residents. It featured several saloons, a general store, a meat market, and all the lively trappings of a bustling mining community.

Bayhorse became Idaho’s longest-running silver producer, with its peak production in 1888. But that success was short-lived. A devastating fire swept through the town in 1889, destroying many buildings. Later that year, a shortage of water slowed mining operations. Then, a drop in silver and lead prices delivered the final blow, leading to the closure of the mines. By 1925, Bayhorse was completely abandoned.

Today, several fascinating remnants still stand, including the 1882 stamp mill and the ruins of charcoal kilns once used to produce fuel for the smelter. The weathered wooden buildings and mining equipment give Bayhorse an authentic, eerie “Wild West” vibe that makes it one of the most photogenic ghost towns in Idaho.

If you love scenic drives, mining history, and hauntingly beautiful places, Bayhorse absolutely belongs on your Idaho road trip itinerary!

Idaho City Ghost Town

Once the largest city in the Northwest, Idaho City is one of the most fascinating ghost towns in Idaho—and it’s also among the easiest to visit.

Founded in 1862 during the Idaho Gold Rush, this former mining boomtown has a remarkable history. In fact, Idaho City’s gold rush was the second largest in U.S. history, second only to California’s famed gold rush a few years earlier.

During its peak in the mid-1860s, Idaho City was home to over 7,000 residents—making it even larger than Portland at the time. More than 200 businesses lined its streets, including three dozen saloons, plus hotels, shops, and various other frontier establishments.

As the mining industry eventually declined, so did the population. However, unlike many ghost towns, Idaho City was never fully abandoned. While its population dwindled to just over 100 residents at one point, today it’s home to around 485 people—meaning you might feel some eyes on you while exploring the old streets… they’re not ghosts!

Start your visit at the Boise Basin Museum, which is housed in the town’s former post office and packed with historic photos and gold rush artifacts. Afterward, take a stroll along the wooden boardwalks to admire well-preserved 19th-century buildings, including the old county jail, courthouse, and various trading posts.

Idaho City offers a mix of history, ghost town atmosphere—plus modern-day shops and restaurants sprinkled in. It’s a must-see stop for history lovers and road trippers!
