Across the United States, old railway lines have found new life as scenic bike paths, known as rail trails. Many routes combine the charm of history with the joy of cycling, often passing through quiet countryside, small towns, and natural landscapes. Because they follow the gentle grades of former train tracks, rail trails are accessible to riders of all ages and skill levels. Understanding top paths offers a chance to connect with local history while enjoying safe, car-free cycling adventures.
The Great Allegheny Passage – Maryland to Pennsylvania
The Great Allegheny Passage (GAP) is one of the most celebrated rail trails in the U.S., stretching 150 miles from Cumberland, Maryland, to Pittsburgh, Pennsylvania. Once part of a major rail corridor, the route now offers a smooth ride through Appalachian scenery, crossing historic viaducts and passing through tunnels.
Highlights include the Eastern Continental Divide and the impressive Big Savage Tunnel, both rich in engineering history. Along the way, towns like Frostburg and Connellsville provide convenient stops for food, lodging, and a look at preserved train stations. Many cyclists pair this ride with the C&O Canal Towpath for a longer journey all the way to Washington, D.C.
Katy Trail State Park – Missouri
Running across much of Missouri, the Katy Trail is the longest developed rail trail in the country, covering nearly 240 miles. Built on the former corridor of the Missouri-Kansas-Texas Railroad (nicknamed the “Katy”), the trail follows the Missouri River for significant portions of its length, offering sweeping views and access to charming river towns.
The route passes through wine country, farmland, and areas rich in Lewis and Clark expedition history. Interpretive signs along the trail share stories of railroad heritage and local culture. The mostly crushed limestone surface makes for a comfortable, leisurely ride ideal for multi-day touring.
High Line Canal Trail – Colorado
Located in the Denver metro area, the High Line Canal Trail is a unique mix of urban and natural scenery. While not as remote as some rail trails, it follows a historic irrigation canal built in the late 19th century to support local agriculture. Today, the 71-mile route offers a combination of paved and unpaved segments suitable for casual rides or full-day cycling adventures.
Cyclists can enjoy cottonwood-lined paths, views of the Rocky Mountains, and stretches that pass through historic neighborhoods. The gentle grade and variety of landscapes make it a popular choice for both commuters and recreational riders.
Trail of the Coeur d’Alenes – Idaho
In northern Idaho, the Trail of the Coeur d’Alenes stretches for 73 miles along a former Union Pacific Railroad route. This paved path passes through forests, wetlands, and along the banks of Lake Coeur d’Alene and the Coeur d’Alene River.
The trail’s history is tied to mining and railroad development, and its transformation is part of an environmental restoration project that preserved both the land and the railway heritage. With multiple access points, it’s easy to ride shorter sections or tackle the entire route. Wildlife sightings—such as eagles, moose, and herons—are common, adding to the trail’s appeal.
Greenbrier River Trail – West Virginia
The Greenbrier River Trail offers a quieter, more secluded cycling experience. Spanning 78 miles through the Allegheny Mountains, it follows the path of the Chesapeake and Ohio Railway’s Greenbrier Branch. The trail features numerous bridges, tunnels, and scenic views along the river it’s named for.
Because the trail is largely away from major roads, it’s an excellent choice for those looking to immerse themselves in nature. Historic depots and small communities along the way give glimpses into the area’s past, while the steady, gentle grade ensures a comfortable ride.
Where History Meets the Open Path
Cycling along historic rail trails offers more than just a workout—it’s a way to experience the landscapes, towns, and stories that shaped the nation’s transportation history. From the sprawling Katy Trail in Missouri to the mountain views of the Great Allegheny Passage, each route blends heritage with the joy of open-air travel.
Whether you’re seeking a multi-day adventure or a leisurely afternoon ride, rail trails provide a safe, scenic, and enriching way to explore the U.S. one pedal stroke at a time.
