Most Wyomingites have soaked in the Thermopolis hot springs and have likely camped, fished or biked at Glendo State Park. 

But how many of us have visited Names Hill Historic Site near LaBarge or stopped to look at the Ames Monument at the highest point on the original transcontinental railroad route? 

Chances are, not many of us. In fact, most of us likely visit the same places year after year, returning to our favorite campsites at our favorite state parks, national forests or reservoirs. 

But just as the national park system offers far more than Yellowstone and Yosemite, Wyoming’s state parks supply some pretty remarkable hidden gems, including 12 parks and more than 20 historic sites. Each is steeped in history and adventure, culture and beauty. And as the national parks face a summer with diminished capacity in the face of federal workforce cuts, consider spending these hot months visiting Wyoming’s overlooked sites. 

To help you on your journey, WyoFile talked with Wyoming State Parks and Historic Sites Director Dave Glenn about his top five overlooked state gems.

Seminoe State Park: Solitude with a side of fishing

“It takes quite a bit of work to get there,” says Glenn about Seminoe State Park. “Which means you can always get a site.”

He’s not exaggerating. Nestled against the Seminoe Mountains, the park sits about 35 miles north of Sinclair off Interstate 80 in southern Wyoming. 

The park boasts a reservoir full of trout and walleye with nearby sand dunes perfect for exploring. It also provides easy access to the Miracle Mile section of the North Platte River for anyone interested in floating or wade fishing. 

But for Glenn, solitude is the real draw.

“There just aren’t a lot of people there,” he says. “You can wander around the nearby wilderness study area or watch bighorn sheep.”

Bring binoculars for a chance to see hawks and eagles along with migratory birds, ducks, pelicans and geese. Go for the day or stay the night. You likely won’t need a reservation. 

Medicine Lodge Archeological Site: Thousands of years of history

Tucked into the Bighorn Mountains in north-central Wyoming rests an archeological site with 10,000 years of stories. And learning about those stories became easier with the site’s new interpretive center, Glenn says. 

“It’s really one of a kind,” he says. “You walk from season to season and through time, including interviews with tribal members.”

The Medicine Lodge Archeological Site includes a 750-foot-long sandstone cliff with hundreds of petroglyphs and pictographs. 

The area also offers a campground in iconic red rock country, a cottonwood river bottom and a creek running through. Fish from your campsite or bring your horses and leave them in the corrals when you’re not riding.

“It’s a great mix of outdoor recreation with past human history.”

Piedmont Charcoal Kilns: Perfectly preserved heritage

Glenn will take just about any excuse to veer off Interstate 80 while traveling across the bottom of the state. And in the southwest corner, that reason is the Piedmont Charcoal Kilns. 

The 30-foot-tall cones look like beehives rising from the prairie. They were built in 1869, and used wood gathered in the Uinta Mountains to produce charcoal shipped to Utah. While charcoal kilns exist in other areas, the Piedmont site is one of the country’s most intact and preserved. 

“For years, I’d driven by and never stopped to see them,” Glenn says. Once he did, he realized they were more than worth the stop, available to the public to view, explore and learn more about for free.

Wyoming Territorial Prison: See where Butch Cassidy did time

On Laramie’s western edge sits one of the state’s oldest buildings: The Wyoming Territorial Prison. You won’t miss it if you drive by. “It looks like an old prison,” Glenn says. 

While the architecture is impressive, as are the surrounding old West buildings — including a church, a mercantile and cabins — the real intrigue rests inside. 

Cells fill the inside of the prison, including ones you can walk into and imagine what life was like in a territorial prison. Large plaques hang on the walls featuring headshots of inmates with their backstories, including tales of murder and mayhem, shootouts and cattle rustling. 

The prison also contains a small museum dedicated to Butch Cassidy’s story including artifacts from his life. 

“It’s a powerful piece of Wyoming history,” Glenn says. 

Oregon Trail Ruts: Retrace a journey

Imagine what pioneers must have felt as they traveled through Wyoming’s harsh, high desert landscape on their way west. They hit blizzards and thunderstorms, crossed raging rivers and tangled with rattlesnakes and bears. 

And in eastern Wyoming, right outside Guernsey State Park, you can see where those wagons coursed across the landscape. Ruts sometimes up to five feet deep cut through soft sandstone, visible a short walk from the site’s parking lot. 

“You look at that sandstone, and go ‘holy cow, how many horses and wagons had to go over this to create grooves that deep?’” says Glenn. 

The site has a picnic shelter and restroom. Anyone interested in camping in the area can head over to Guernsey State Park.
