Alternative Transportation

Well-known for its earth-friendly policies, Boulder ranks second in the nation for non-auto transit. Only Manhattan has a higher percentage of its workforce using alternative transportation options. Boulder is committed to building “complete streets” and providing workers, residents, and visitors with options for getting into and around town.

The Boulder Creek Path and its connecting network of walking/biking trails allow travel in and around almost anywhere in Boulder without relying on a car. Most of the city’s 28 miles of paved trails are safely off-road, while an additional 200 miles are available as bike lanes on major streets.

Boulder’s Community Transit Network buses navigate Boulder and beyond every 10 to 20 minutes, giving residents low-fare access to, from and around the city. Special services are also available for sports fans and bicycle riders, as well as discounted fares for frequent RTD users, senior citizens, riders with disabilities and commuters.

The Regional Transportation District (RTD) provides affordable local, regional and express bus service throughout metro Denver, including Boulder County. Boulder operates several centrally located Park-and-Ride facilities for commuters.

Future transportation options include FasTracks, a metro-wide passenger train system.
