Trail Alerts & Closures

The Colorado Trail is a spectacular adventure through some of the state’s best backcountry.

There are many ways to enjoy The Colorado Trail, from a day-hike, bike, or ride, to a multi-day trip or end-to-end excursion beginning in either Denver or Durango. There are dozens of access points to the CT’s 567 miles of trail. These are accessible by car, 4-wheel-drive, bike, horse, on foot, or even by train. Numerous resources, including maps, guidebooks, and websites can help you with your planning. The CTF Facebook groups are also a great resource for trail conditions and information sharing, find links on our Trail Alerts page. But there is no place better to begin your journey than right here. Continue browsing this page to find information on everything from modes of travel, to what to carry, to weather and trail etiquette.


When to Go

The “season” for The Colorado Trail is primarily 3 months: July, August, and September. Before this 3-month season, users encounter troublesome snowpack remaining from winter and spring storms. After these months, fall storms begin bringing new snows that can be deep and long lasting. (Here’s a video that shows how a snowstorm can ‘up’ the challenge of distance hiking.)


Trip Planning

Trip planning can be a lot of fun, as nearly every past CT traveler has described their lead-up to the journey. This is your opportunity to learn about the Trail, and doing so in advance will enhance your trip. Most Trail users, especially those planning multi-day trips, will find that they want to delve more deeply by obtaining our official CT guidebook. During the lead-up is also when you’ll likely begin coordinating with one or more individuals as helpers or resources. Often, the support people will need the CT Guidebook with its information about road access and more.
