Looking for a trail? Check out the The Colorado Trail Explorer!

Colorado Parks WildlifeThe Colorado Trail Explorer (COTREX) is an online interactive map 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.

The Colorado Trail Explorer map breaks down the trails by four different categories: Non-motorized trails, motorized roads or trails, bike routes and recreational routes. You can also search for trails up to 25 miles away from your location and break down the search by trails that allow bikes, horses, pack animals, OHVs or trails that have season restrictions.

So far the map holds about 85% of Colorado’s trails – but it will continue to grow.
