■ ABOUT COTREX
The Colorado Trail Explorer 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 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 230 land managers.
