Know what to watch out for by checking the google map below before your travels on the CT.

Colorado Trail Foundation offers many resources for traveling the Trail, below is a custom Google map that marks the location of Trail work locations and crew campsites. We will also flag any major trail obstructions, reroutes, and planned closures. The Foundation does not map or track current Trail conditions, scroll to the bottom of this page for suggested resources on current conditions. For Trail information, The Official CT Guidebook is the single best resource for planning your excursion.

We wouldn’t be able to provide this information or perform Trail maintenance without your support, donate today.

Current Trail Conditions


Weather & Snowpack

Higher elevations bring more extreme weather. Find links to weather stations for CT segments on our Weather page. And see our page on snowpack for current snow level data and historic trends for melt-dates.



CT Facebook Groups

The foundation maintains an active facebook page. We also recommend the many private groups created specifically for CT  thru-hikers, section hikers, mountain bikers, etc.

Reroutes on the CT

The Colorado Trail is in continual transition and has been since its completion in 1987. In its earliest incarnations, the Trail was a combination of existing backcountry trails, Forest Service roads, mining roads and trails, abandoned railroad right of way, and miles of new trail hacked out by volunteers stitching it all together.

Over the years, much of that original tread has been modified, added to and moved from steep, unsustainable sections. Gradually, new single-track has replaced roadway. Still, some 100 miles remain open to some motorized use and it is the goal of The Colorado Trail Foundation to eventually move as many of those miles as possible to non-motorized track. As a result, CT users should expect to encounter reroutes as they traverse the length of the Trail.

Reroutes Happen Every Season

Short reroutes are built nearly every season and lengthier modifications every few years. All are aimed at improving the Trail experience for all types of users.

A consequence is that older guidebooks no longer describe the current CT route. That’s why we recommend buying or borrowing the latest edition of the official Guidebook, Databook or Map Book,  especially before taking an extended trip on the Trail. That said, even the most recent editions of those guides can be slightly inaccurate due to subsequent route changes. That should be no cause for alarm, however. Most changes are minor and easy to follow.

In addition, planned and unplanned events can necessitate routing changes. For example, work on the Strontia Springs Dam in 2011 shut down the first few miles of Segment 1 for several months. Alternative starting points to reach the Trail were offered. Wildfires also have temporarily closed sections of the Trail for days, and even weeks, requiring users to find alternate routes.

Collegiate West Reroute

Starting with the 2013 trail season, we added 80 miles of trail to the CT known as the Collegiate West. It is co-located with the Continental Divide National Scenic Trail and is ‘must see’ spectacular. Read more about the Collegiate West.

In 2014, major reroutes opened on the Collegiate West, including the most prominent, a 23-mile single-track upgrade that eliminates similar mileage on roads and motorcycle trail. The part from Cottonwood Pass to Tincup Pass Road closely tracks the Divide and includes trail construction that causes nearly every hiker to marvel.

In coming years, the CTF, USFS and others will be constructing trail on additional stretches of the Collegiate West to reroute sections that still follow roads and motorcycle trail.

Access Route Status

The US Forest Service is useful in providing information on the condition of backcountry access routes (Forest Service roads, etc.) to CT trailheads.
