■ VIEW ADVISORIES, CLOSURES, AND CONDITIONS FROM OFFICIAL SOURCES

■ ABOUT COTREX
Colorado Trail Explorer aims to map every official trail in the state of Colorado. 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.
COTREX is unique in that the app only shows information from official sources. No unreliable crowdsourced information or recommendations from someone on the other side of the country. Everything you see in COTREX has been reviewed and approved by the managers and experts local to that area.
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.
■ DISCLAIMERS
[Battery Life] We do everything we can to make the app low power when recording, but GPS is notorious for reducing battery life.

Does not show game hunting units in Colorado. Worthless for hunting.
