DENVER — The Colorado Department of Natural Resources and Colorado Parks and Wildlife have released the Colorado Trail Explorer (COTREX), Colorado’s Official Trails App.

COTREX is a free web and mobile trails application utilizing over 39,000 miles of public trails in Colorado. Residents and visitors can use COTREX to discover and navigate trails on federal, state, local and private lands with public access. Additionally, COTREX is built for all trail users, including hiking, mountain biking, equestrian riding, and motorized recreation. 

“The COTREX app is a marriage of Coloradans’ love of the outdoors and using the latest technology to discover more of our beautiful state,” said Alex Dean, Trails and Recreation Project Manager, Colorado Department of Natural Resources. “We are excited for Coloradans to download the COTREX app. It’s a great tool for exploring our wide diversity of trails and encouraging more Coloradans to spend time outdoors.”

Originally created as part of former Colorado governor John Hickenlooper’s Colorado the Beautiful initiative, the free application offers many new features, including:

The COTREX project began as part of former Governor Hickenlooper’s Colorado the Beautiful Initiative in 2016. To bring this project to life, Colorado Parks and Wildlife spent years doing data outreach and development. This culminated with a web-only version that was published in 2017. The State contracted Natural Atlas in May of 2018 to further develop the state’s trails data and to build Android, iOS, and web browser versions of an interactive planning and navigation application.
