Colorado Trail Explorer (COTREX)
COTREX is a 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 key to using COTREX is understanding the map’s legend. The line’s color corresponds to the primary type of recreation allowed on a recreational trail or road:
Hike & Hoof
(human powered uses)
||Motorized Roads & Trails||Cars, OHV, 4x4|
||On-street Bike Route|
Be aware that specific uses vary on a trail by trail basis. Mouseover trail lines for a quick summary. Click on trails to open a full description.
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 as part of its mission to provide enjoyable and sustainable outdoor recreational opportunities that educate and inspire current and future generations to serve as active stewards of Colorado’s natural resources.
Both the CTS data and COTREX online apps represent the first iteration CPW is sharing publicly. It is envisioned that CPW will continue to incrementally improve on these 1.0 versions as resources permit.
