The ideal time to hike this segment is typically from late June through September. During this period, the snow has usually melted, and the weather is generally more stable. Be aware that afternoon thunderstorms are common in the summer, especially above treeline, so an early start is always recommended.
The terrain is challenging, featuring a substantial initial climb for the first eight to nine miles, which is generally well-graded but continuous. After this, the trail becomes steeper and breaks out above treeline, offering expansive views. You'll find ample tree cover during the initial climb, fields of wildflowers, and sections that follow an old railway. Be prepared for exposed areas above treeline and some sections affected by pine beetle kill.
Yes, dogs are generally allowed on this segment of the Colorado Trail. As it passes through the San Isabel National Forest, it's crucial to keep your dog under control, preferably on a leash, to protect wildlife and ensure a pleasant experience for all trail users. Always pack out pet waste.
No, you do not need a specific permit to hike Colorado Trail: Segment 15, nor is there an entrance fee for the San Isabel National Forest where it is located. However, always practice Leave No Trace principles and be aware of any specific regulations for dispersed camping if you plan an overnight trip.
The segment connects US Highway 50 to Marshall Pass. You can typically find parking at the trailheads near US Highway 50 or at Marshall Pass. Overnight parking regulations can vary, so it's advisable to check with the local Forest Service office for the most current information regarding long-term parking at these access points.
This segment offers incredible panoramic views, especially from above treeline, where you can see prominent 13,000-foot peaks like Mount Ouray and Chipeta, and even distant views of the Sangre de Cristo Range and the Great Sand Dunes. You'll also pass by Fooses Dam and follow the Fosses Creek Trail. The trail also converges with the Continental Divide Trail for several miles.
Water sources, such as streams, are generally available throughout the first nine miles of the segment, particularly during the initial climbing phase. However, it's always wise to carry sufficient water for your hike and be prepared to filter or treat any water collected from natural sources.
Yes, after about 6 miles into the segment, the route converges with the Continental Divide Trail and the Monarch Crest Trail for several miles. It also briefly touches sections of the Colorado Trail Seg. 14 Chalk Creek Trailhead to US-50, Collegiate East, and Collegiate West.
This segment is considered a "difficult" and "expert route" due to its significant elevation gain and the exposed sections above treeline. While the climb is generally well-graded, it is strenuous. It is not recommended for beginners and is best suited for experienced hikers who are prepared for challenging conditions and rapid weather changes.
Given the challenging nature and exposure above treeline, essential gear includes plenty of water, high-energy snacks, layers of clothing (even in summer), rain gear, sun protection (hat, sunscreen, sunglasses), a map and compass or GPS device, a first-aid kit, and sturdy hiking boots. Trekking poles can also be very helpful for the climbs and descents.
When hiking above treeline, especially on this segment, be highly aware of rapidly changing weather conditions. Afternoon thunderstorms with lightning are common, and temperatures can drop quickly. Plan to be off exposed ridges by early afternoon. Always check the forecast before you go and be prepared to turn back if conditions worsen.
