Boulder is a special place for bicyclists. The Boulder Valley has more than 300 miles of bikeway, including 96 miles of bike lanes, 84 miles of multi-use paths, and 50 miles of designated bike routes. With more than 300 days of sunshine, and an active culture that nurtures it, biking is one of the best ways to get around Boulder. Of course, our bike-friendly community didn't happen by chance; it is the result of decades of community efforts and thoughtful planning.

The City of Boulder's dedicated bikeways include on-street bike lanes, contra-flow bike lanes, designated bike routes, paved shoulders, multi-use paths and soft-surface paths.

Where Can I Ride My Bike on the Sidewalk?

Riding bikes on the sidewalk is prohibited downtown on and around the Pearl Street Mall and in most commercial areas. Here's a detailed map pdf of where bikes are and are not allowed to be ridden. 

Bike lanes

Typically located along arterial streets and shown in red on the 2019 Bike/Ped map pdf, these portions of the road are reserved exclusively for bike travel.

 This map pdf details where bikes are and are not allowed to be ridden on the sidewalk. 


Some bike routes are enhanced with a shared lane arrow (sharrow). This pavement marking is placed approximately three feet into the travel lane from the parking lane, adjacent right-turn lane, or curb and shows bicyclists where to ride and motorists where to expect bicyclists.

Multi-use paths

Boulder's multi-use paths are physically separated from streets for non-motorized travel, and are shared by bikes, pedestrians, runners, skaters and non-motorized scooters. Multi-use paths can be a paved or soft surface.
