With bikeable trailheads, shuttles, transit-friendly routes and improved regional connections, there are more ways to access Boulder’s open space. 

Consider leaving your car at home for your next outdoor adventure with Boulder’s Open Space and Mountain Parks. With bikeable trailheads, shuttles, transit-friendly routes, improved regional connections, and even shared scooters and bikes, there are more ways than ever to access Boulder’s open space. 

The city is working to expand trailhead access and build new trail connections that help people reach open space more easily, reduce emissions, ease congestion and improve the outdoor experience for everyone. While more improvements are on the way, many options are already available to reach open space without a car. 

Ride or Roll to the Trailhead within the City 

  • Bikes and e-bikes: OSMP trailheads in Boulder are bikeable for many community members and offer several racks for secure parking. Throughout 2025, the city is investing in more bike racks at area trailheads and access points throughout many neighborhoods to improve biking access. View a map of biking trails in Boulder. Learn more about where e-bikes are allowed on city open space.  
  • Park-to-Park shuttle: The Park-to-Park shuttle provides free satellite parking and free shuttle service to and from Chautauqua Park on summer weekends and holidays, from Memorial Day weekend through Labor Day.
  • Shared bikes and scooters: While operating Lime scooters on city open space is not permissible, you can take a Lime scooter to most trailheads within city limits (like Sanitas and Chautauqua). There are two Lime Groves near Chautauqua (8th and Baseline, and Baseline between Lincoln and 10th) that are within a mandatory parking zone. There are discounts for income-qualified community members and adaptive e-scooters for community members experiencing disabilities. You can also take an e-bike to a few trailheads including the Peoples’ Crossing and Chautauqua. The city’s bike sharing partner, BCycle, has a variety of stations throughout the city.

During 2025, the city is also conducting trailhead improvements to improve shuttle access at area trailheads.
  • Hessie trailhead shuttle: The free shuttle provides service between Nederland High School and the Hessie Trailhead. In 2025, the free shuttle service runs Friday to Sunday from May 24 through October 6. Combine the Hessie Shuttle with RTD’s NB Route and leave your car at home.
