Taking the Bus to OSMP

Go Green to Open Space and Mountain Parks: Sustainable Transportation to OSMP Trails

Like your skies blue? So do we! Here at the City of Boulder, we're committed to reducing smog (and road rage and traffic congestion!) by reducing the number of cars on our roads. You can help by curbing your car when possible and biking or busing to trailheads. 

Discover further options for getting around town at GO Boulder or map your bike route to your favorite trailhead at GO Bike Boulder.

All OSMP trailheads and many access points have bike racks pdf so you can bike to your hike! 

Open Space and Mountain Parks Trailheads and RTD Service

Busing is a smart, environmentally-conscious way to reach many OSMP trails. RTD (our Regional Transportation District) operates public transit services in the Boulder/Denver area. The table below lists RTD routes that serve OSMP hiking trails.

Ride for Free!
If you hold an Eco Pass, Neighborhood Eco (NECO) Pass, Buff Pass from the University of Colorado/Boulder or many other bus passes, you can ride the bus for free.  Learn more about Boulder’s bus routes at GO Boulder.

Bike and Bus
RTD buses have bike racks if you want to bus and bike to a favorite trail. Some bike racks fill quickly, so please have alternate plans (such as waiting for the next bus or locking up your bike) if the bike racks on buses are full. All OSMP trailheads have bike racks.

Many trails are easily accessed by bus (see below.) Check RTD Route Schedules for up-to-date information.
