New Multi-Agency Trails App
The City of Boulder and 11 other agencies created a mobile application available for iOS and Android devices. The Boulder Area Trails app provides access to all trail information in and around Boulder County. The app is designed to enable users to find trails by use or type, plan routes by connecting local community trails, and link to the appropriate agency websites for more information. Before you head out, be sure to hit the app’s refresh button at the bottom left on a WiFi network to ensure you see all the trails!
City of Boulder and city Open Space and Mountain Parks (OSMP) regulations for dogs, bikes and horses may differ from other agencies and municipalities that maintain open space trails. Currently, all e-bikes are prohibited on OSMP trails but allowed on multi-use, paved paths within the City of Boulder. Please pre-plan your trip by reviewing city regulations to help our community members enjoy and protect their open spaces.
