Lyons is a Statutory Town in Boulder County, Colorado, United States.

In 1979, it was saved from demolition and converted into the town's history museum by the Lyons Historical Society.

Its rock, from the Permian period, about 260 million years ago,[10] is considered the hardest sandstone in the world, and has a unique red or salmon color.

The Denver, Utah and Pacific Railroad laid narrow gauge tracks into Lyons in 1884 to serve the quarries.

All access routes to the town were blocked, and sewer and fresh water service was disrupted.

The National Guard began evacuating the entire town of Lyons on September 12 at daybreak.

They include commercial, residential and public buildings: Lyons is located in northern Boulder County.

The Lyons Redstone Museum started out as the town's school house, built in 1881.

The Lyons Historical Society fought for three years, and it was rewarded with use of a building to establish their history museum in.

The first floor has historic displays (including an old bank teller cage, re-created living room and kitchen area, quarry and small farm equipment, musical instruments, dairy equipment, and more).

The first-floor work area contains the town's history archives (mainly newspaper clippings), video interviews and documentaries of its pioneer families, and a small gift and book shop.

The second floor has some displays (like ice cream parlor booths), but mainly it has dozens of archival black-and-white photographs of early Lyons, from the 1880s to 1940s.

Since the 1881 building did not open as a museum until the 1970s, some of the records are incomplete regarding early town history, but it is extensively covered by the locally produced books and DVD documentaries.

An annual booklet had quotes from the artists, and contained a story that people could follow as they took the Trail.

There are several pieces of permanent public art, including sculptures made of local sandstone, such as giant eggs, flower containers, a fountain, a small performance stage, and more.

In 2008 and 2009, the town renovated its two main streets to include sandstone sidewalks and features, floral decorations, seating areas and sculptures.

In addition to a new stage for the festivals in recent years, they have built the Wildflower covered pavilion which allows for smaller year-round concerts.

The Sounds of Lyons concert series began in 2009, bringing in highly acclaimed classically trained musicians to perform over one weekend in spring.

Area recreation includes mountain biking, hiking, camping, fly fishing, climbing and excellent class II-V whitewater kayaking.

Hall Ranch provides over 12 miles (19 km) of multi-use trails and consists of 3,206 acres (12.97 km2) of back country.

The south end of Picture Rock is 4.5 miles (7.2 km) from the Heil Ranch Trailhead off Lefthand Canyon.
