Colorado’s history climbs from the cliff dwellings of the Ancestral Puebloans to the mining camps of the silver boom, and it carries some of the hardest chapters in the American story alongside its grandest scenery. The state holds ground where Native peoples were attacked, where strikers were killed, and where Japanese Americans were imprisoned during World War II, all of it set against canyons, fossil beds, and the Rockies.
I taught American history for decades before retiring in 2018, and Colorado is a place where the landscape and the history are impossible to separate. The 15 sites below mix National Park Service units with state landmarks, historic railroads, and museums. Several call for quiet reflection. All of them are worth the trip.
If you are planning a wider trip, our guides to the most visited national parks and the least visited national parks can help you balance the crowds.

15. Ludlow Massacre Memorial
In April 1914, during a long and bitter coal strike, the Colorado National Guard and company guards attacked a tent colony of striking miners and their families at Ludlow. The fighting and the fire that swept the camp killed more than 20 people, including two women and 11 children who suffocated in a pit beneath a burning tent. It became one of the darkest moments in American labor history.
117 public lands destinations are under threat. Get the free briefing that 27,000+ people use to stay informed and take action.
The United Mine Workers of America owns the site and maintains a stone memorial to those who died. It is a National Historic Landmark and a quiet, open field today. Stand here and read the names, and the cost of the early labor movement becomes real.
14. Mayflower Mill
Just outside Silverton, high in the San Juan Mountains, the Mayflower Mill processed gold and silver ore from 1929 well into the 1990s. Also known as the Shenandoah-Dives Mill, it is one of the best-preserved ore mills in the country, with much of its machinery still in place.
The mill is a National Historic Landmark, cared for by a local historical society. Self-guided tours walk you through the milling process, from the aerial tramway that brought ore down the mountain to the tables that separated the metal. For mining-history buffs, it is a rare intact look at how the work was done.
13. Durango and Silverton Narrow Gauge Railroad
Since 1882, narrow-gauge trains have climbed the rugged canyon of the Animas River between Durango and Silverton. Built to haul silver and gold from the mountains, the line now carries passengers on one of the most scenic rail journeys in North America, still pulled by coal-fired steam locomotives.
The railroad is a National Historic Landmark and a working tourist line. The round trip is a full day, winding along cliffs above the river into the high country. Riding it is the closest thing to time travel that Colorado offers.
12. Molly Brown House Museum
Margaret Brown, remembered by history as Molly Brown, survived the sinking of the Titanic in 1912 and helped row a lifeboat and urge it back to look for survivors. Long before and after that night, she was a Denver philanthropist and activist for workers, women’s suffrage, and children. Her restored Victorian home sits in the city’s Capitol Hill neighborhood.
Run as a museum by a nonprofit, the house offers tours through period rooms that tell her full story, far richer than the unsinkable legend. It is one of Denver’s most engaging historic homes.
11. Hovenweep National Monument
Straddling the Colorado-Utah border, Hovenweep preserves a cluster of stone towers and dwellings built by Ancestral Puebloan people roughly 700 years ago. The structures perch on the rims and boulders of shallow canyons, their fine masonry still standing after centuries in the high desert.
The National Park Service manages the monument as a remote, quiet place far from crowds. A loop trail leads past the main group of towers near the visitor center. The dark skies here are among the best in the country for stargazing.
10. Kit Carson County Carousel
In the small eastern-plains town of Burlington spins one of the rarest treasures in Colorado. The Kit Carson County Carousel, built by the Philadelphia Toboggan Company in 1905, still carries its original hand-carved animals and its original paint, a survival almost unheard of among antique carousels.
It is a National Historic Landmark, owned by the county and run in summer. For a few dollars you can ride it to the sound of its restored band organ. It is a small, delightful piece of early American amusement history.
9. Bent’s Old Fort National Historic Site
On the plains of southeastern Colorado, along the Santa Fe Trail, Bent’s Fort was the great trading crossroads of the 1830s and 1840s. Traders, trappers, soldiers, and Cheyenne and Arapaho people met here to exchange goods on the edge of Mexican and American territory.
The National Park Service has reconstructed the adobe fort on its original footprint, and costumed interpreters bring the trading post to life. Walking through its rooms gives a vivid sense of frontier commerce before the wars that would soon reshape the West.
8. Florissant Fossil Beds National Monument
About 34 million years ago, volcanic eruptions buried an ancient lake and forest near present-day Florissant, preserving an astonishing fossil record. The monument protects petrified redwood stumps as wide as a room and delicate fossils of insects, leaves, and fish captured in fine shale.
The National Park Service runs a visitor center and trails that lead past the giant stone stumps and through meadows full of wildlife. It is a window into a Colorado that was once warm, wet, and unrecognizable.
7. Sand Creek Massacre National Historic Site
On a November morning in 1864, U.S. volunteer soldiers attacked a peaceful camp of Cheyenne and Arapaho people along Sand Creek, killing around 230, most of them women, children, and the elderly, even as the camp flew an American flag and a white flag. It stands among the worst atrocities in the history of the American West.
The National Park Service preserves the site in partnership with the Cheyenne and Arapaho tribes whose ancestors died here. There is little built on the land, by design. A trail and overlook let visitors reflect on what happened. Come with respect and quiet.
6. Dinosaur National Monument

Along the Colorado-Utah border, Dinosaur National Monument protects a remarkable wall of dinosaur bones still embedded in the rock where they were buried roughly 150 million years ago. The Quarry Exhibit Hall, on the Utah side, lets visitors stand before hundreds of fossils in place.
The Colorado side of the monument is wilder, a land of deep river canyons cut by the Green and Yampa. The National Park Service manages both. Between the fossils and the canyons, it covers an enormous sweep of natural history.
5. Amache National Historic Site
During World War II, the United States forced more than 7,000 Japanese Americans, most of them U.S. citizens, into a camp near Granada in southeastern Colorado. Known as Amache, or the Granada War Relocation Center, it was one of ten incarceration sites where families lived behind barbed wire because of their ancestry.
Congress made Amache a unit of the National Park System in 2022, and the National Park Service now preserves it, working alongside survivors and descendants who long tended the site themselves. Foundations, a reconstructed barrack and guard tower, and a cemetery remain. It is essential and sobering ground.
4. United States Air Force Academy
North of Colorado Springs, against the backdrop of the Rampart Range, lies the United States Air Force Academy, where the nation trains its future officers. The campus opened in the late 1950s, and its sharp modernist architecture made it instantly famous.
The standout is the Cadet Chapel, with its row of soaring aluminum spires, one of the most recognized works of modern American architecture and a National Historic Landmark. A visitor center explains the academy’s mission. Note that access can change with security needs, so check ahead before visiting.
3. Black Canyon of the Gunnison National Park

Few places in the country feel as dizzying as the rim of the Black Canyon. The Gunnison River has carved a gorge so narrow and so deep that sunlight reaches the bottom only briefly, leaving the walls in shadow much of the day. Some of the cliffs drop more than 2,000 feet to the river below.
The National Park Service protects the canyon with rim drives and overlooks on both the south and north rims. Our guides to Black Canyon of the Gunnison facts and things to do in the park will help you plan a visit.
2. Pikes Peak
Rising to over 14,000 feet west of Colorado Springs, Pikes Peak is one of the most famous mountains in America. The view from its summit so moved the writer Katharine Lee Bates in 1893 that she penned the words that became the song America the Beautiful. The peak is a National Historic Landmark.
You can reach the top by car on the toll highway, by the historic cog railway, or on foot up the long Barr Trail. A summit visitor center waits at the top, often above the clouds. It is a quintessential Colorado experience.
1. Mesa Verde National Park
In the canyons of southwestern Colorado, the Ancestral Puebloans built elaborate stone villages into the alcoves of the cliffs roughly 800 years ago. Mesa Verde protects more than 600 cliff dwellings, including Cliff Palace, the largest in North America, with its towers and rooms tucked beneath an overhanging ledge.
Mesa Verde was the first national park created to preserve the work of human hands, and it is a UNESCO World Heritage Site. The National Park Service offers ranger-guided tours into the major dwellings, which require tickets. For a broader plan, see our list of the most visited national parks.
More Things To Do In Colorado
Colorado’s historic sites spread across the whole state, from the cliff dwellings and railroads of the southwest to the plains memorials of the southeast and the museums of the Front Range. A road trip rewards picking a region and going deep rather than racing across the map.
