CATCO is free and runs Monday through Saturday.

It's Clean, It's Free, It's Convenient. The Clean Air Shuttles are brought to you by the Town of Castle Rock through the Clean Air Transit Company (CATCO). The shuttles are powered by compressed natural gas, a clean-burning fuel that reduces air quality impacts. 

Shuttle buses run Mondays through Saturdays except Thanksgiving Day, Christmas Day and the Fourth of July. Three different schedules are provided for riders' convenience. CATCO runs on a bi-directional route system. 

A Midtown route serves downtown, Metzler Ranch and The Outlets at Castle Rock, with service running from 7:15 a.m. to 5:37 p.m.

The Crosstown Eastbound route serves Founders Village, downtown and The Outlets at Castle Rock beginning at 7:15 a.m. and terminating at 5:58 p.m.

The Crosstown Westbound route serves The Meadows, Red Hawk, downtown and The Outlets at Castle Rock (which will provide a person access to FREX), beginning at 7:16 a.m. and continuing through 5:56 p.m. Click on the schedule below for a list of stops on each route.

The CATCO shuttles carry up to two bicycles with wheels 16 inches or larger (sorry, the bike racks are not equipped to hold recumbent and tandem bicycles). The bike rack is on the front. To place a bike on the rack, users should pull the spring-loaded rack down and lock the bike into place. Once the destination is reached, users may then unload their bicycles from the rack. Feel free to ask drivers for a bike rack operation handout.

The CATCO Board of Directors oversees the management of the Clean Air Transit Company. Members of the Board are local business people. The Town of Castle Rock's Public Works Commission oversees the operation of the Town's local transit service. The Town of Castle Rock is committed to creating solutions to traffic congestion and parking issues as well as maintaining the air quality in our community.
