Bustang to Rocky Mountain National Park

Seasonal Shuttle Service From Boulder

The glory of Rocky Mountain National Park's mountain trails, abundant wildlife and natural wonders that make it a bucket-list destination are now even more accessible from Boulder.

On weekends and holidays, May 24 through September 28, 2025, you can ride the Bustang from Boulder Junction at Depot Square Station straight into Rocky Mountain National Park (RMNP). You must purchase a RMNP pass to ride the shuttle into the national park — but bus riders do not need a timed-entry reservation! 

The Boulder pickup stop is at Boulder Junction at Depot Square Station, Gate S3 (on Pearl Parkway). There will be no service at this stop on May 26 or September 28, 2025, due to citywide events on those dates.
