​​​​​​​​​​​​​​​Colorado’s Snowmobile Registration fees provide funding for more than 2,700 miles of groomed and marked winter trails that are open to all winter enthusiasts.

Colorado State Parks has managed the Snowmobile Program since its inception in 1977. Through a longstanding partnership between Colorado State Parks and the Colorado Snowmobile Association (CSA)​, this program has grown substantially over the years. It​ also funds the Snowmobile Safety Certification Program, the Snowmobile Program operators, helps support the avalanche warning system and provides for patrol services to ensure safe snowmobiling and registration compliance.
