With the Flatirons rising above town and an extraordinary network of paths, bike lanes, mountain trails, and foothill climbs, Boulder has earned its reputation as one of America’s great cycling cities.

Whether you are a road cyclist looking for a serious climb, a mountain biker searching for singletrack, a commuter traveling across town, or a visitor hoping for a relaxed afternoon ride, Boulder offers an impressive range of options.

The numbers tell part of the story. The City of Boulder reports more than 300 miles of bikeways across the Boulder Valley, including 96 miles of bike lanes, 84 miles of multi-use paths, 50 miles of designated bike routes, and more than 80 bicycle and pedestrian underpasses.

Boulder also remains nationally recognized for bikeability. In the 2026 PeopleForBikes City Ratings, Boulder scored 66 and ranked No. 10 among medium-sized U.S. cities.

Why Boulder Is Such a Great Bike City

What makes Boulder special is the variety of riding available within a relatively compact area.

You can follow a creekside path through town, ride a marked loop around the city, practice at a purpose-built bike park, explore open-space trails, or climb directly into the foothills.

Boulder’s extensive network of multi-use paths and underpasses also makes it possible to cover significant distances while avoiding many busy intersections. For riders looking to explore the city, the B360 provides a 24-mile loop around Boulder, while the B180 offers a shorter 12-mile alternative.

Boulder Creek Path

For visitors and casual cyclists, the Boulder Creek Path is a natural starting point. The popular multi-use corridor follows Boulder Creek through the city and connects with parks, neighborhoods, downtown areas, and other parts of Boulder’s path network.

Because the path is shared by cyclists, walkers, runners, children, and other users, riders should control their speed, keep right, and communicate before passing.

B180 and B360 Routes

The B180 is an excellent introduction to Boulder by bicycle. At approximately 12 miles, it provides a manageable tour for recreational riders.

For a bigger outing, the 24-mile B360 circles the city and showcases Boulder’s interconnected cycling network. Both routes are especially useful for visitors who want to explore beyond downtown.

Best Mountain Biking Around Boulder

Marshall Mesa and Doudy Draw

South Boulder offers some of the area’s most scenic riding, with open landscapes and memorable Flatirons views.

The Marshall Mesa and Doudy Draw area is popular with riders looking for dirt and mixed-surface adventures close to town. Riders should check the official trail map and current conditions before heading out, since bicycles are allowed only on designated trails and muddy conditions can lead to closures.

Betasso Preserve

Located west of Boulder, Betasso Preserve is one of the area’s best-known mountain biking destinations.

The Canyon Loop is 3.3 miles and rated moderate to difficult by Boulder County, while the Benjamin Loop adds another 2.4 miles. Bikes are prohibited on Wednesdays and Saturdays, directional riding rules apply to the major loops, and e-bikes are prohibited.

Valmont Bike Park

Valmont Bike Park is one of Boulder’s most distinctive cycling attractions. The 42-acre park provides terrain for a wide range of abilities, from riders learning basic skills to experienced cyclists looking for jumps and technical challenges.

It is an excellent place to build confidence and improve bike-handling skills without leaving the city.

Classic Boulder Road and Gravel Rides

Flagstaff Road

Flagstaff Road is one of Boulder’s signature road climbs. Beginning close to town, the road climbs steeply into the foothills and rewards riders with expansive views.

The climb is demanding, and cyclists share the road with vehicles, so visibility and controlled descending are essential.

Chapman Drive and Sunshine Canyon

Chapman Drive offers a popular unpaved climbing experience close to town, while Sunshine Canyon provides another classic route into the foothills.

Both demonstrate one of Boulder’s greatest cycling advantages: challenging climbing begins almost immediately beyond the city streets.

Left Hand Canyon

For experienced road riders, Left Hand Canyon offers a long and scenic climb into the mountains. Strong cyclists can create challenging combinations involving Ward and other nearby mountain roads.

Weather and temperatures can change significantly with elevation, so riders should carry appropriate layers, water, and repair equipment.

Boulder Bike Rules to Know

Cyclists on Boulder open-space trails must stay on routes specifically designated for bicycles. Riders should yield appropriately, slow down around other trail users, and communicate clearly when passing. About 58 miles of City of Boulder Open Space and Mountain Parks trails are designated for bicycle use.

E-bike rules depend on the class of bike and the location. Class 1 and Class 2 e-bikes are permitted on city streets, bike lanes, multi-use paths, and certain designated city open-space trails. Class 3 e-bikes are prohibited on City of Boulder multi-use paths and open-space trails.

Because rules differ between city and county properties, always check the managing agency before riding an unfamiliar trail.

Why Boulder Biking Is Different

In Boulder, cycling is more than recreation. The same network serves commuters, students, families, elite athletes, mountain bikers, gravel riders, and visitors.

That combination of infrastructure, scenery, access, and cycling culture is difficult to match.

You can spend an hour cruising beside Boulder Creek, circle the city on the B360, ride dirt trails with Flatirons views, or test yourself on a legendary foothills climb.

Check current conditions, choose a route that matches your ability, wear a helmet, bring the right equipment, and enjoy the ride.

In Boulder, some of the best views come from behind a set of handlebars.
