About

The Colorado Trail Explorer (COTREX) endeavors to map every trail in the state of Colorado in support of the Colorado the Beautiful Initiative. COTREX connects people, trails, and technology by coordinating the efforts of federal, state, county, and local agencies to create a comprehensive and authoritative repository of recreational trails for public use.

This project is led by Colorado Parks and Wildlife (CPW) and Department of Natural Resources, but is only made possible through partnerships with organizations at every level statewide. COTREX represents a seamless network of trails managed by over 225 land managers.

Your Participation Has an Impact

By recording Trips and Notes or submitting Trail Reports and other feedback, you help inform and inspire the entire community. Other users can make better informed decisions or discover locations they may not otherwise. Trail managers gain insights into current conditions and can more rapidly respond to safety considerations or shape future planning.
