Want to head out into nature without a car? The City of Boulder has compiled a list of resources to expand trailhead access through other modes of transit. Check out the trailhead cameras to help plan your adventure.

RTD has confirmed their proposed changes will now take place effective Aug. 31. Take a look at the new schedules on the RTD bus schedule website. The new changes include:

• Boulder Junction at Depot Square Station will reopen with the AB2 (Airport bus) and FF4 (Flatiron Flyer 4) bus routes, connecting Boulder to Denver International Airport and downtown Denver respectively. Join Boulder Chamber Transportation Connections, RTD and other transportation leaders on Sept. 3 for a reopening celebration!
• Weekday AB2 airport trips will now depart from Boulder Junction Depot Square Station instead of Downtown Boulder Station. Saturday service between Downtown Boulder and DIA will operate as AB3 to reduce confusion.
• The FF2 and FF4 Flatiron Flyer will have more trips during peak hours.
  • FF2 Eastbound: 3 morning trips (7:00 to 8:30 a.m.) and 2 afternoon trips (4:00 to 5:30 p.m.)
  • FF2 Westbound: 2 morning trips and 3 afternoon trips
  • FF4: 8 new peak-hour trips in each direction for morning (7:00 to 8:30 a.m.) and afternoon (4:00 to 5:30 p.m.)
• Westbound FF5 trips in the afternoon and evening will now travel via I-70 to I-25 and continuing onto US 36 to avoid congestion on I-270.

All CU students and employees are eligible for a free Boulder BCycle CU student and employee membership, thanks to a partnership between CU Boulder's Environmental Center and BCycle. 

This membership gives you unlimited rides under 60 minutes - perfect for getting around campus or between CU locations. Just download the Boulder BCycle app and use your identikey@colorado.edu email address when registering. Learn more about BCycle.

To make your commute safer and more convenient, campus has added a new section of buffered bike lane along 18th St. connecting the Broadway multiuse path to Euclid Ave. In addition to the bike lane, an access ramp was added off of the multi-use path to the street-level bike lane.

We’re streamlining Buff Bus service for greater efficiency! The Will Vill, Will Vill Limited, and Bear Creek loops have been consolidated into a single clockwise route named “Route W: Williams Village.” This new route design features mostly right-hand turns to help improve travel time and reliability. It serves both the Darley and Bear Creek stops in Williams Village. Our other Buff Bus routes, including the Stampede and East Campus Express, will continue operating as usual during this phase. See the new routes and schedules for fall 2025.

CU Boulder students, faculty, and staff will benefit from expanded HOP service as the Boulder Junction Depot Square Station reopens. The HOP will now service Pearl Parkway, Junction Place/32nd Street, and Walnut Street. The HOP still runs every 15 minutes during peak hours and connects CU Boulder, University Hill, downtown Boulder, and 29th Street Mall. To achieve a fully electrified HOP fleet by 2030, Boulder is adding 7 battery electric buses this fall.
