Welcome the Colorado Trail Explorer – desktop map!
COTREX is an online application connecting Coloradans and visitors to rewarding trail experiences by enabling anyone with a browser to explore over 39,000 miles of recreational trails.
The Colorado Trail Explorer (COTREX) is powered by the Colorado Trail System (CTS) mapping project.
Colorado Parks and Wildlife (CPW) is leading the CTS effort which aims to map every trail in the state. Providing enjoyable and sustainable outdoor recreational opportunities that educate and inspire current and future generations to serve as active stewards of natural resources helps CPW meet its mission.
Both the CTS data and COTREX online apps represent the first iteration which CPW is sharing publicly. It is envisioned that CPW will continue to incrementally improve on these 1.0 versions as resources permit.
