The Legislature’s recent bill regarding rafting and the rights of outfitters to utilize waterways through private lands has brought significant attention to the sport. You can find information on registered river outfitters using the State of Colorado’s rafting business license database. See also the Department of Regulatory Agencies’ Office of Outfitters Registration page. You can also read about regulations for river outfitters in DORA’s 2009 Sunset Review of River Outfitters. Colorado State Parks also has information for river outfitters on their site.
