Boulder County Trails App

New Multi-Agency Trails App

Boulder County and 11 other agencies are currently working to develop a new county-wide, interactive, mobile trail map application.

The application will include trails from

  • Boulder County
  • City of Boulder
  • City of Longmont
  • City of Broomfield
  • City of Lafayette
  • City of Louisville
  • Town of Superior
  • Town of Erie
  • Town of Lyons
  • Town of Nederland
  • Rocky Mountain National Park
  • USFS

The application aims to

  • Connect local communities
  • Provide access to all trail information in and around Boulder County
  • Provide “one‐stop shopping” for users
  • Enable users to find trails by use or type
  • Allow users to plan routes
  • Link users to agency websites for more info
  • Allow for offline mobile use

The new app will be released in the summer of 2019!

Tips & Tricks

  • Zoom around the map before heading to your destination. This will cache and save the map so you can use it even when you are not connected to the internet.
  • Locate Me works best on devices with GPS.
  • This application does not include other local agency trails such as City of Boulder or United States Forest Service trails.
